  6. North Carolina Planolites

    The rain here in North Carolina gave me a bad case of cabin fever yesterday so I decided to jump in the car and drive out to a location that based on my limited knowledge should be Triassic in age. My original intent was just to collect some loose matrix to process for micro fossils but once I started looking around I couldn't resist the urge to hit something with my rock hammer. Needless to say it didn't take me long to realize that my simple rock hammer was just not going to work on most of the rocks but I was able to walk away with a couple of interesting pieces. I believe two of the pieces contain Planolites and the other two I am no sure of. I will attempt to post some photos as soon as I can get them cleaned up. I was also curious if any of the Forum members might have photos of Planolite specimens they have collected and could possibly post.
  7. Season End

    Season closing Yesterday my buddy and I did our probably last trip for this year. Snow was lying in the clearings around our location but the location we went to was free of snow. All in all it was a good year. We made about 15 trips found lots of good ammonoids and 3 new locations too. The last trip was successful too. We found Ladinian ammonoids in excellent preservation but it was hard work to get them out. Kind regards Andreas

  14. I was at a local Barnes & Noble yesterday and bought a copy of the newly-published Scientific American Special Edition on dinosaurs (Volume 23, No. 2, Summer 2014). I think it's just a compilation of several of their recent dinosaur-related articles pasted into one volume but it's a nice collection for the kid of any age who can't get enough "dinosaur books" or someone who wants to get generally up-to-date while flying cross-country. It's priced at $9.95 and tagged as available on newsstands until August 4
  15. Hello On my second fossil trip this year I decided to do a little exploration in an area which was hitherto not visited by me. It didn’t take long and I stumbled over a limestone block that shows the typical lower Carnian (Julian) oxidic hardground crust. I was surprised because the geological map of this area only shows Norian strata. The weathered brown and black, oxidic cauliflowers like structures (by the point of the chisel) within the limestone are microbial reef build-ups of the sessile foraminifera Tolypammina gregaria, WENDT and Frutexites sp. They are a sign for less to zero sedimentation during a very long time. After splitting the block did not show many fossils. Only some orthocone nautiloids were visible. Then I found an ammonoid (Sphingites meriani MOJS.) and therefore I decided to take that block with me and prep out all orthocone nautiloids. Normally my focus is more on ammonoids because they are easier to insert into the Triassic timescale. During prepwork several small lower Carnian ammonoids pulled out. Prep take roughly 30 hours. Ammonoids: Arcestes periolcus MOJS., Monophyllites simonyi HAUER, Dittmarites sp., Sirenites sp., Trachyceras sp., Pompeckjites layeri Nautiloids : Syringoceras sp., Orthoceras triadicum MOJS., Orthoceras dubium(HAUER) Aulacoceras cf. inducens(BRAUN) All prepwork was done with different pneumatic chisels. The orthocone nautiloids mark the direction where the current comes from. All orthocone nautili do not lay in the same limestone horizon. Therefore several different current angles are visible.
  16. Hello all! Recently, I had the chance to meet up with a few forum members, and hunt the historic Granton Quarry, in North Bergen NJ. Last Monday, March 31st, I was up at the crack of dawn, 4:00 am, to hit the road and meet my partner for today, forum member Jeffrey P, in Newburgh, NY. I left my house in central Connecticut at 4:15 am, eager to be on the road, and heading towards the Triassic exposures of the Lockatong formation. An hour and a half later, after encountering heavy downpours and sporadic showers, I arrived at the appointed meeting place, a McDonalds parking lot, just off of Interstate 84. Meeting time was 6:00 am, and I arrived around 5:45am. Overly anxious? Not me. I was a little concerned about the weather, as ice pellets were beginning to hit my windshield as I waited for Jeff to arrive. Oh boy. Jeff showed up just after 6:00am, and after our initial greetings, and moving his gear to my truck, we got on our way. Jeffrey and I had collected together before, at my fossil fish site in Connecticut, so the trip down to North Bergen was a fun time talking over our expected strategies for this site, and how different this site was from my usual stomping grounds. We hit a bit of traffic heading into North Bergen, and arrived at our destination, around 7:20 am. Now, … Jeffrey had made two previous scouting expeditions to the site, and had a hunch on where we might find some productive layers of fossils. He had scored some clam shrimp and even had a very nice and possibly complete Diplurus newarki, a Triassic coelacanth! We were both hopeful, but realistic as the Newark Supergroup is notoriously hit or miss. For those unfamiliar with the area, the old Granton Quarry is gone, and on top of what was the main quarry floor, a Lowes Home Improvement Center now resides. There are still exposures of the Lockatong accessible to the north of the actual building., however. This exposure was our target. We stopped in to the Lowes, and met with the manager, Ray, who was perfectly willing to allow us to collect from the exposures on their property, so long as we stayed out of the way of any pending deliveries. We assured him we would be as unobtrusive as possible, and having received permission to hunt the exposure,, headed back to the car to get our gear. At this point, the other half of our collecting team arrived. John (Flyguy784) and his buddy Ken. I have been friendly with John since I joined the Forum back in 2010, and we have conversed fairly regularly, having bonded over our mutual frustration over hunting the Newark Supergroup. John is more of a plant guy, but we had talked in the past of a Granton trip, and when I mentioned to him that I was planning on going, he wanted to come up, if only just to get a chance to collect together. Meeting him, and putting a face to the name was a most welcome part of this trip, and we happily exchanged some fossils between us. It was now around 7:55, and we decided to gear up, and check some of the lower exposures, to see what could be found. The sky was gloomy looking, a light drizzle was falling, and the wind was blowing cold – a gray and fairly miserable start. Water was streaming off of the rocks above, in little runnels which felt great, sliding down your back. In the past, the Granton Quarry has yielded assorted fish, reptile/dino footprints, a little plant material, and some reptile material, including phytosaur teeth and coprolites, a gliding lizard (Icarosaurus) aquatic lizards, (Tanytrachelos) . We all had high hopes, but they were realistically tempered by our various experiences with hunting similar Newark Supergroup sites in the past. We collected the in the black and gray shales infrequently finding bits and pieces of both clam shrimp, and coprolites. Things continued in this vein for a few hours. We finally started to find assorted disarticulated bones of the coelacanth Diplurus newarki! Eureka! By this time, the rain had stopped, the sun came out, and the temperature was rising, steadily. At this point, we narrowed down the hunting to the lower few inches of a seam of black shale, the lower 2 inches of which were extremely friable, and nearly impossible to get out of the wall in any decently sized slabs. After finding a number of cool coelacanth bits, coprolites, and Estheria ovata clam shrimp slabs, between us, we decided around noon-thirty-ish to take a break for lunch, and retired to our cars in the Lowes lot. We snacked, talked fossils, and other various sundry things. An enjoyable time to be sure. We soaked up the sun, and enjoyed it’s warmth on our faces. At least my feet were no longer numb from the earlier cold! My companions were all amiable, and we enjoyed the time together. This is the type of outing that can be enjoyed, whether finding anything, or not. But, we were finding things, so we got back too it. We then decided to take the folding ladder I had brought, and try to access the higher layers of black shale which Jeffrey had managed to climb up to on a previous excursion, and remove a bit of shale that had yielded his Diplurus coelacanth. We set the ladder up, and took turns removing shale, and bracing the ladder for each other. When we got tired of removing rock, we stopped, took a break to split what we had removed, and then switched places. This garnered us some larger slabs, that, while they didn’t provide us with any complete fish, did reward us with some mortality plates of the Estheria ovata, and some more bits and pieces of Diplurus newarki. We continued in this way, while John and Ken scouted some of the lower seams of black shale. Time, as is always the case, flew away from us, and before we knew it, 4:00PM was approaching, and we needed to leave by then to make it home at a reasonable time. We packed up our things, said our goodbyes, and got on our way. Traffic leaving Jersey was smoother than coming in, so we were back to the McDonalds in Newburgh just around 5:00 PM. Jeff and I said goodbye, and went our separate ways. I headed home, to be stymied getting to the Beacon Bridge, for about a half an hour …just to get 3.5 miles or so. I finally arrived home to Connecticut at around 7:30 pm, excited by my finds and a successful hunt in the Lockatong Formation – The Newark Supergroup had blessed me with a few Upper Triassic finds for my collection. Thanks for looking – enjoy the pics. Regards, John (Flyguy 784- background) and JeffreyP (foreground) One area we tried to attack Continued...

  20. Dear Fossil Forum members! This report deals with ammonoids from the former zone of Protrachyceras archelaus, which is our present Longobardian within the Ladinian stage of the marine Triassic timescale. Fig.1 A beautiful view of the surging “rock waves” of the incoming tectonic thrust sheets. The valley between the two Mountains in the middle of the picture marks the tectonic border between the mainly Triassic Hallstatt Unit and the Tirolikum Unit of the Totengebirgs nappe (in the background). History Since the beginning of the geological research within the Northern Calcareous Alps of Austria in the middle of the 19th century, about 500 species of Triassic ammonoids have been described in great Monographs by Mojsisovics, Hauer, Diener and other early authors. The ammonoids described therein came from upper Anisian to uppermost Norian aged parts of the Hallstatt limestone in Austria. Only in the lower to middle Ladinian period, a gap exists in the rich ammonoid record of these early researchers. This gap was explained by them as an interruption of sedimentation in the Ladinian time or tectonically reduced Ladinian strata during the genesis of the Alps. During these early days no one thought of a collecting gap because Ladinian ammonoid faunae were well described and known from several localities in the Southern Alps and the Bakony Mountains in Hungary. In 1882 Mojsisovics pictured ammonoids of Anisian and Ladinian age in his monographic work “Die Cephalopoden der mediterranen Triasprovinz”. The locations mentioned therein reach from the upper Anisian Schreyeralm limestone here in Austria to several Ladinian locations of the former Austrian provinces Südtirol, Lombardy and the kingdom of Hungary, which were also part of the former Austrian-Hungarian Monarchy at this time. Included in this work were also Scythian and Anisian ammonoids from Croatia and Bosnia-Herzegovina. Fig.2 Frontpage of Mojsisovics second great monograph from the year 1882. “The detailed accurate descriptions and illustrations provided by Mojsisovics are unquestionably the greatest contribution by a single author towards appreciating the astonishing beauty and variety of Triassic ammonoids” (cit. E. T. TOZER). Therefore every recent Triassic ammonoid researcher includes these old works in the standard literature of Triassic ammonoids. These old works were so to speak, a cornerstone for building the marine middle and upper Triassic timescale of our days. Unfortunately the early stratigraphic scales of Mojsisovics had some mistakes. Originally the stratigraphic position of the “Norian” stage was set by him below the Carnian. He used the term Norian for the time frame we today call Ladinian. Mojs. thought that most parts of today’s real Norian Hallstatt limestone of Austria were of the same age as real Ladinian strata in the Southern Alps. Some misinterpret location data, i.e. the wrong assumed position of the fineclastic Zlambach marls as base of the Hallstatt limestone led him to this wrong assumption. It was the Austrian geologist Alexander Bittner, a contemporary of Mojsisovics, who introduced the term Ladinian into literature by recognizing the false assumptions of Mojsisovics. The name Ladinian was chosen by Bittner after the Ladinian folk of the Southern Alps/Dolomites. At this time this area was also part of the Austrian-Hungarian monarchy with its capital Vienna and it’s so called “Vienna school” of the palaeontology institutions there. Probably this “miss take” of Mojsisovics led to some changed ammonoid zones within the Norian timescale, which last into the 20th century. It was the merit of the Canadian Triassic worker E.T. Tozer to correct this long lasting error by establish his own North American Triassic timescale, based only on North American, mainly Canadian Triassic ammonoid locations. The pelagic (deeper marine) Triassic sedimentation in Austria starts with the uppermost Anisian Flexo-Ptychites beds/lenses of the Schreyeralm limestone. This is also the base of the Hallstatt formation. The next frequent ammonoid lenses/layers occur within uppermost Ladinian/lower Carnian strata in this formation. The lower to middle Ladinian time frame in between was not well documented with ammonoids by the early researchers of the 19th century. At some historical locations the lower Ladinian part is/was given but was not really recognised by them. Later, modern researchers used microfossils to determine the placement of large parts of the grey to violet limestone in the Hallstatt formation into the Ladinian. Within the 20th century also scarce ammonoids were mentioned from these middle Ladinian strata. Fig.3 Anisian Schreieralm limestone with cross sections of Flexoptychites sp. Fig.4 Monophyllites sphaerophyllus (HAUER) from the Schreieralm limestone In general, ammonoid locations are not frequently known within the Ladinian part of the Hallstatt limestone. The most common fossils are Crinoid stem parts, Bivalves and Conodonts. The limestone facies consists of red to grey, sometimes yellowish to grey coloured limestone which is locally interbedded with marls. Also strongly condensed successions are common there and fossils also do not occur in continuous layers. Comparable Ladinian ammonoid faunas are also well known from similar Hallstatt type limestone in Greece and Italy. They show similar ammonoid faunae of Ladinian to Carnian age. In the Tethys realm the whole Ladinium is split into two subdivisions today. Upper Ladinian = Longobardian, Lower Ladinian = Fassanian, The historical zone ammonite of the Longobardian is Protrachyceras archelaus (LAUBE). Fig.5 Protrachyceras archelaus (LAUBE), in MOJSISOVICS “Die Cephalopoden der mediterranen Triasprovinz“ Wien 1882 Tafel XXXL, Fig. 1, But Protrachyceras archelaus LAUBE do occur within a longer time span and is therefore not perfect for stratigraphic aims. The old archelaus zone of the Ladinian was therefore changed into several Longobardian and Fassanian ammonoid zones of today. Within the Tethys realm the Longobardian is split into the ammonoid zones of: Daxatina canadensis Frankites regoledanus Protrachyceras longobardicum The Fassanian is split to the ammonoid zones of: Eoprotrachyceras gredleri Protrachyceras margaritosum Eoprotrachyceras curionii The ammonoids shown in this report come from a condensed fossil bed roughly inserted to the turquoise marked ammonoid zones of the timescale below. Historical Ladinian locations The condensed lower Carnian fossil lenses on the famous historical Feuerkogel show almost all a portion of the upper Ladinian at their base. This is also visible at other Lower Carnian locations within the Hallstatt limestone. During the last years Proarcestes sp. from a new location are sometimes shown for sale in the internet. They are sometimes identified as Arcestes sp. from Norian strata. But it is Proarcestes, therefore its Norian age is definitely wrong. I visited this new locality a few years ago. All locations there are of Ladinian age which is evidenced by Proarcestes cf. subtridentinus, Anolcites sp. and Epigymnites sp. This fauna is maybe slightly younger than the fauna shown later here in this report. Fig.6 Some Epigymnites arthaberi (MOJS.) and Epigymnites moelleri (MOJS.) from the above mentioned location The new location Several years ago a friend and I were lucky to find a hitherto unknown middle Ladinian ammonoid location during a prospecting trip. At this location the normal limestone succession is penetrated by several fractures and tectonic influence across the normal layer direction is also visible there. The fossil layer itself, in which ammonoids were frequent, consists of a very strong condensed upper part of lower Longobardian age, indicated by Protrachyceras longobardicum (MOJS.), and a lower part of a slightly older age indicated by scarce last descendants of Ptychites cf. pauli MOJS. which show deeply incised second and third lateral saddles similar Aristoptychites or Arctoptychites. Therefore the location is ranged by me to the transition of the ammonoid zones of Protrachyceras longobardicum and the underlying Eoprotrachyceras gredleri zone. Outside of the Tethys realm this is roughly comparable to the zones of Meginoceras meginae MC LEARN and Tuchodiceras poseidon (TOZER) of the North American timescale. Both zones are known from the Triassic of British Columbia in Canada too. Tozer, 1994, wrote that flat forms of Protrachyceras sikianum MC LEARN are comparable with Protrachyceras longobardicum (MOJS.) and the thicker morphs of Pt. sikianum MC LEARN with Pt. archelaus (LAUBE). Fig.7 View of the lower, sometimes more greyish limestone part of the fossil layer. The chisel points to a Sturia cf. semiarata MOJS. The furrows on the limestone block have their origin in the strong condensation of this limestone. One can recognize by this feature the underlying part of a condensed limestone (fossil) layer. Fig.8 In contrast to the above shown picture, a view of the underside of the overlaying layer where craters/hollows are visible. These two features can be used for recognizing up and downside in strongly condensed limestone. This feature is independent from the Triassic age of the rock and occurs in condensed limestone of Jurassic age too. The right hanging limestone block contains the fossil layer. Fig.9 Protrachyceras longobardicum (MOJS). in situ. View from the underside. The upper half of the ammonoid was totally dissolved due to the extreme condensation of the uppermost limestone layer at this location. In this location P. archelaus occurs very scarcely. It is no good indicator for stratigraphic aims here at all. A normal collector can use the following features to insert ammonoids into the Ladinian timescale. The frequent occurrence of Proarcestes sp. with a wavy end body chamber is a sign for Ladinian age. All forms of Sturia sp. are restricted to the late Anisian and Ladinian. The occurrence of real Ladinian Protrachyceras MOJS. The following picture will show you the main differences between Protrachyceras, Trachyceras and Neoprotrachyceras. Fig.10 In contrast to Trachyceras the venter furrow of real Protrachyceras MOJS. is bordered by nodes which show a single point per node. Protrachyceras are restricted to the Ladinian. Real Trachyceras show “broader” nodes with two or three points a node bordering the venter furrow. Trachyceras is frequent in the Lower Carnian (Julian) The genus Neoprotrachyceras KRYSTYN looks similar toTrachyceras but shows also just one point per node, sometimes changing up to two points per node within maturity. Neoprotrachyceras is restricted to the uppermost Lower Carnian and lowermost Upper Carnian (e.g. the genus Spirogmoceras SILBERLING in the Dilleri Zone of the North American Tuvalian) For a newbie collector it is difficult to find some fossils in the Hallstatt limestone at all. To place them into the right ammonoid zone is sometimes the easier part of the exercise. Fig.11 A weathered cross section of Proarcestes sp., visible at the limestone wall. Notice the bleached limestone surface in contrast to the colour of the fresh rock. Fig.12 Talus block with visible cross sections of ammonoids and orthocone nautiloids Natural picture size is 20cm. The edges of the fossils are deeply weathered in. This can be a sign that the fossils will probably split out well. Small idiomorphic Biotite crystals up to one mm in size, fine Feldspar crystals and thin greenish tuffitic crusts around some ammonoids and limestone clasts indicate a distant simultaneous volcanic event, adjacent to the palaeo Hallstatt realm. This is the very first observation of volcanic fallout/washout within the Hallstatt limestone column. Within other tectonic nappes in the Northern and Southern Calcareous Alps (Dolomites) volcanic (Tuffitic) ash layers are a frequent feature in Ladinian time. In the adjacent Tirolic nappe some volcanic/tuffitic events are evidenced near the base of the archelaus zone. The middle Ladinian fauna listed below was found at this location. Ammonoidea cf.

Brachiopoda: Discinisca sp. Austriellula dilatata (SUESS) Important ammonoid species of the archelaus zone A beautiful, conspicuous faunal element of the archelaus zone is Protrachyceras longobardicum MOJS. the zone ammonoid of the Langobardicum Zone This species shows its maximum roughly in the lower middle of the former archelaus zone and can be used well for stratigraphic aims. As mentioned earlier in this report compressed variants of Protrachyceras sikanianum MC LEARN are comparable to Pt. longobardicum MOJS. The thicker variants of Pt. sikanianum rather resemble Pt. archelaus LAUBE. Fig. 13 Protachyceras longobardicum MOJS. with Proarcestes ombonii TOMMASI and Proarcestes cf. subtridentinus MOJS.

Looks like a fossil Limpet gastropod (Patellidae) but in reality it is an inarticulate Brachiopoda Fig. 19Sturia cf. semiarata together with Proarcestes cf. ombonii The most frequent faunal element of the Ladinian within the Tethys realm is Proarcestes BRONN. This genus occurs with several species up to Carnian strata. In our location Proarcestes subtridentinus MOJS. and Proarcestes ombonii TOMMASI was often found. The second one can reach the dimension of a small ball. Fig. 20 Proarcestes subtridentinus Fig. 21 Monophyllites wengensis (KLIPSTEIN) In the Hallstatt limestone this genus starts with the Anisian Monophyllites sphaerophyllus via the Ladinian M. wengensis up to the Carnian M. simonyi. Within the descendants of the Triassic Phylloceratida the ancestor of the Jurassic Ammonitida is supposed. Fig. 22 Ptychites cf. pauli MOJS. This species of Ptychites show deeply incised second and third Lateral saddles. I think that this is a feature of allmost all "late" species of Ptychites.

  21. For those of you who have dreamed about Middle and Upper Cambrian trilobites in western Utah, this is the publication that will open the door to exploring. The Utah Geological and Mineralogical Survey has printed many well done booklets and books on Millard County, Utah. The intent was to draw in Petroleum Geologists to explore the general areas, but also provide a wealth of information to those interested in Paleontology and Cambrian Stratigraphy. To the west side you can even be directed to Triassic Ammonites, with Pennsylvanian and later outcrops also in the vicinity. The camping possibilities are everywhere. Some box canyons are wonderful... but trying to find a flat spot can be challenging. When I say flat... everything is either up hill... or down hill. You have the Topaz Mountains to the north, Dugway Geodes (good luck finding one...) and Pioche, Nevada mining areas further to the west. Excellent cheeseburgers in Pioche, by the way. The area is... wide open and lacks facilities. So gas up, water up, block ICE and get groceries in Delta. It might be 45 miles to this area... you can check it on the road map... but you cannot miss it. But... finding the right road(s) can be tricky as they split and take a different course quickly. My recommendation... look for the 100 foot power lines strung over the flat country and once you intersect them near shale outcrops... you have arrived. To the north is the U Dig site which is marked along the way as well, and cuts off to the right from some popular Middle Cambrian exposures.

  22. Recently I had a pretty decent day hunting the scarce petrified wood in the Triassic (Newark supergroup) of southeastern Pennsylvania. The largest piece in the photo weighs 13.5 lbs (6.1 kilos). It was the first specimen found in the first 5 minutes of the hunt, so I was hoping a good day would follow. And more nice wood did follow that first one. As usual, most pieces have a brownish hue, and the silica sparkles a bit. No agatized wood. Scale bar at photo bottom is 4 inches (10.16 cm).
  23. Ladinian Ammonoid Prep

    Servus folks It is raining the whole day and now it starts snowing. This year’s collecting season is over and prep work has started two weeks ago. Always preparing in the lab makes no fun to me. So I took a break and wrote this short story about the preparation of a Ladinian ammonoid slab. The first picture shows the situation when I found the location. If you look carefully you can see some round cross-sections of orthocone nautiloids and some longish cross-sections of ammonoids. At this moment it was only a guess what ammonoid species was hidden behind this longish edges. My first intention was Epigymnites and therefore Ladinian in time. The second picture show the worked out blocks comparing the fossils. At this moment I knew that it was Ladinian and that my guess was right for the genus. I knew also that there were 3 individuals of Epigymnites in the parts. The third picture shows the result of roughly 10 hours prep work. Unfortunately the preservation of the ammonoids was not good as expected. But in the Triassic strata of Austria Ladinian locations and ammonoids are scarce to find. The last picture shows the result of my preparation work. The plate shows Epigymnites cf. moelleri MOJS.(uppermost one) The typical double row of fine knots is visible only on this amonoid. Alas not the best preservation but absolutely worth to put it into my Triassic ammonoid collection. kind regards Andreas
  24. Triassic Ichnofossils

    Hi All, Well it's about time I post something from Holland and no... it's not sharkteeth Here are some of the possible footprints one can find in the classic Winterswijk locality covering the Anisien Triassic period. Although it's called muschelkalk it really is not.. not in the sense of the muschelkalk we have in Germany.. They are Procolophonichnium haarmuehlensis, a small trackway with tens of footprints from a tiny creature... reptile? Second is a larger Rynchosauriodes Paebodyi. Trackways from this reptile are very rare and due to the creatures size... impossible to bring home I have more at home.. will post if you like em
  25. Hi everyone ! Just discovered this forum and thought I should give it a go regarding identifying some trace fossils. I am currently working with the sedimentology of the Upper Triassic on Svalbard and in the Norwegian Barents Sea. Several trace fossils has been observed in the field and it would of course help a lot to identify them when it comes to the sedimentological interpretation. So, feel free to comment. - Picture 1 shows a vertical 'tube' burrow in a heterolithic setting (mud + sand). The preliminary interpretation is that it was deposited in the offshore-transition zone. Could also have been in a shallower pro-delta environment. Could it be Skolithos, or is it to 'wiggly' and thick? - Picture 2 shows a similar trace fossil (same facies as described above). - Picture 3 also shows one or two vertical burrows (same facies as described above). - Picture 4 shows some apparently vertical traces (same facies as described above). - Picture 5 shows a vertical trace found in a flaser heterolithic setting (90% sand + 10% mud). As you can see, it cuts through the layers and bends them a bit downwards. Preliminary interpretation is a tidal sand flat. - Picture 6 and 7 shows some thick horizontal burrows. Found in a 1 m thick sandstone with hummocky cross stratification and wave ripple cross lamination. Preliminary interpretation is a lower shoreface setting. Could it be Rhizocorallium? Cheers!
