  1. Recently visited the Green Mill Run area in NC and found some fossils that thought would peak some interest but need the help of identification. I know the site can have a bit Cretaceous but also Eocene and Pliocene, so it can make it harder to identify things. The first one I assume might be crocodylian or maybe turtle, not sure. Those thick grooves make me think maybe crocodylian. The second seems like, from looking at the root base, a possible theropod tooth? I thought maybe claw of a turtle, but seeing that thick base makes me think otherwise. Lastly found what I think is some claw. Of what? I don't know. Dromeaosaur? The tip is clearly broken off, but the grooves on the underside are clearly noticeable. Any insight would be of great help. Thanks!

    Goblin Shark Tooth

    From the album: Delaware Fossils

    Scapanorhyncus texanus (Roemer, 1852) From the Late Cretaceous spoils of the Chesapeake and Delaware Canal, Reedy Point, Delaware Microfossil - 7.6 mm Not the best example of a shark tooth, but a rare find for Reedy Point. Most shark teeth were found further west.

    Mandible with teeth

    Hello, I have a specimen of a mandible with teeth for your scrutinization. It was found some years ago in the Campanian St. Bartholomä-Formation of the Gosau-Group of Kainach, Eastern Alps, in Styria, Austria. I am little bit concerned about the bone texture and also the arrangement of the teeth. It seems it could be in urgent need for visiting a really skilled orthodondist. What do you think, does it really need some medical treatment? Many thanks for all your comments! Franz Bernhard

    Cretaceous Bryozoan

    From the album: Delaware Fossils

    Idmidronea traceyi, Taylor and McKinney, 2006 Mount Laurel Formation Reedy Point, Delaware
  5. I recently acquired some matrix via trade from @will stevenson. This matrix is from Hallencourt France. Just the second time we gotten to go through the entire process of breaking down matrix to a searchable form. I am still in the process of breaking it down and only have searched probably less than 20%. I wanted to begin the post now as I had a few minutes to write. The material is Early Campanian in age and from the North of France. Unlike my first experience breaking matrix down which was from a location with no publication, there is a publication. Sharks from the Late Cretaceous of France and England by Guinot, Underwood, Capetta, and Ward. There is an additional publication on the Batoids. The publication covers the Anglo-Paris Basin. Hallencourt has a pretty diverse fauna according to the paper and gives us an opportunity to explore Cretaceous micros from Europe for the first time. Most of what we got were pretty small pieces with 4 I’d call medium sized. It is very hard chalk and is pretty challenging to actually break down. It has given me the opportunity to experiment with different methods for breaking down matrix. I’ve used hot water treatments, vinegar and for the largest piece, freeze and thaw for the first time. It has been an exercise in patience lol It is also proving to be an invaluable experience going forward. We haven’t searched enough to really have a full sense of this particular matrix but the early results are mostly Chiloscyllium and Anomotodon. So far, 22 Chiloscyllium teeth and 11 Anomotodon though almost all are partial. Very few complete teeth except the Bamboo teeth. Most surprising find so far is easily a Synechodus. Only one tooth was found during the study according to the paper. We have also found Squalicorax (1), Carcharias (2), Scyliorhinus (1), Squatiscyllium (3) and our first ever Eoptolamna tooth ! There is A LOT of dermal denticles in this matrix and at least 5 distinct types. We also found one small Shark vert. Its a grind. Quite a bit of work. Way less dense in shark teeth than our Mesaverde stuff was and not real diverse so far but there is a lot of searching left to do. The lack of density does make any find pretty cool though. I will update this with better pictures after everything is completed and I have the final results. I’d like to thank Will for the trade that brought the matrix. Very cool TFF Member!!!! 1st pic the bag of matrix before breaking down 2nd pic Anomotodon hermani 3rd pic a slide with a few of the finds

    interesting cretaceous oddity

    It seems that every time I post in the fossil ID lately, it's something my friends found when they were with me - brand new eyes are really good at avoiding the "routine" we get into when hunting, and they produce all sorts of crazy cool finds as a result. Here are some field photos of something I suspect is fish scales - I can ask her for better photos if needed. Ozan formation, mid-campanian of the cretaceous, Texas Here's a side angle I took so that the ridge is more evident: thoughts?

    Cretaceous shark tooth Belgium

    Hello all During my fossil hunt yesterday, I found these two shark teeth right next to each other. I assume both are the same species, I just don't know which one. They were found in the region around Mons/Bergen in Belgium, where both Campanian and Maastrichtian seem to occur. I don't know exactly which layer these came out of, since I found them in a collapsed wall. Sharks seem to be quite rare here, so really happy with them. As found: The second tooth: Thanks all for your help.

    Some mosasaur teeth; serrated or not?

    During a recent trip back to W.M Browning Cretaceous Fossil Park in Northern Mississippi (Demopolis Formation, Late Campanian) I collected another mosasaur tooth. While incomplete the condition is still very nice. I am aware of the difficulties in identifying isolated mosasaur teeth but have been attempting it nevertheless. If nothing else I've learned more along the way. Two questions for this tooth. The first is the general question if anyone has an idea about the identification. The second pertains to what qualifies as serrations on mosasaur teeth. There are "crenulations" present on this tooth as I would call them but do these qualify as serrations? Among the mosasaurs reported from the Demopolis (Clidastes propython, Halisaurus sp., Mosasaurus conodon, Mosasaurus cf. missouriensis, Platecarpus cf. somenensis, Plioplatecarpus sp., and Tylosaurus sp.) serrations are a characteristic that reportedly separates the majority of them. However, the lack of all facets on the tooth is somewhat unusual in conjunction with the serrations. Am I exaggerating these crenulations as serrations? I posted this tooth once before but thought I'd post it again since it it is from the same site as the new one. I have some reason to believe it may be Mosasaurus missouriensis based on the general shape, number of facets, and cross section, but I've also had difficulty finding reference material for M. missouriensis. Any thoughts? Does anyone have reference photos or material for M. missouriensis?
  10. Hello everyone! This is a partial mosasaur jaw with other associated bones i found in the Early-Mid Campanian Woodbury Formation of New Jersey over the summer. One of my best finds to date.
  11. I have been too busy to get out fossil hunting when I want but there are a few recent times I've been able to get out. I wanted to try and post a small trip report about them. On October 31 I had the opportunity to visit the W.M. Browning Cretaceous Fossil Park in Prentiss County, Mississippi. Most people from the area are probably familiar with this old site but I'm a new resident to this part of the South so I wanted to give it a try. It's Late Campanian Demopolis Formation. It was a little cold and rainy but warm enough for someone used to North Dakota. Apparently these large concretions erode out of a higher formation. First tooth I found wasn't even in the creek but on the bank where I set my sieves. A good sign. A little tributary carving through the bedrock made for relaxing sounds. A little mosasaur tooth. Washing and drying the teeth back home. "Junk" teeth I set aside to use for biology outreach programs. S Some more pics of the mosasaur tooth. A nice Hybodus cephalic clasper. A chunk of cartilage and some verts. A blunted Ischyrizha rostral spine. Keeper fossils. A couple Baculites asper pieces and some Cadulus sp. didn't get in close pictures. I'm always a sucker for lightning and cool color variations in teeth. Serratolamna serrata teeth were the second most common. Squalicorax kaupi Squalicorax pristodontus Hybodus sp. and Pseudohypolophus. Most were missing tips but the Enchodus were a good average size. Xiphactinus teeth were just tips. Some bigger Scapanorhynchys were also present. Baculites asper and Cadulus sp. Anomia argentia The small Gryphaeostrea vomer. Exogyra ponderosa and Pycnodonte convexa (not pictured) were also a common find. Aside from the common material there were some nice rarer specimens and stuff new to my collection. Overall it was a very good trip.

    Istieus grandis Agassiz 1842

    Taxonomy from fossilworks.org. Woodward 1901, p. 66: “Head and trunk much laterally compressed, but elongated. Mouth terminal, the mandible with truncated symphysis and high coronoid region; a single series of small, conical marginal teeth; stouter and blunter teeth within the mouth, but apparently not on the parasphenoid. About 10 branchiostegal rays. Vertebral about 90 to 100 in total number, the centra short and deep, marked with delicate longitudinal ridges. Pelvic fins scarcely smaller than the pectorals, which are inserted high on the flank; dorsal fin extending for more than half of the back; anal fin short, opposed to or behind file posterior end of the dorsal; caudal fin deeply forked. Scales elliptical, not pectinated.” Forey (1973b, p. 151-152) noted that: "The minor differences between Istieus and Pterothrissus are far outweighed by the many important features of similarity...", but did not synonymized Istieus and the recent genus Pterothrissus because Istieus is based on fossils.

    Various sponges

    Hi, i recently received those very nice sponges from @badeend. I asse they're all Hexactinellids. I know identfying sponges even when you have them un grand is a hard thing to do. Any help to try a more precise ID is greatly welcome. Here is the number1, a glass sponges ? Kimmeridgian, Kalberbeg, Netherlands

    Sardinius cordieri (Agassiz 1840)

    Taxonomy from gbif.org. The fish was originally described by Agassiz under the name Osmerus cordieri. Description of the genus by Woodward 1901, p.247 “Head small and trunk moderately elongated, the maximum depth at the insertion of the dorsal fin. Mandibular suspensorium much inclined backwards, and cleft of mouth large; jaws slender, and maxilla not expanded behind; teeth minute, numerous and sharply pointed. Gill-rakers large and slender. Vertebrae about 45 in number, half caudal and half abdominal; the centra at least as long as deep, longitudinally striated; ribs delicate. No fin-rays elongated, but two or three in front of the median fins undivided and spinous. Pectoral fins with about 18 rays, relatively large and inserted just above the ventral border; pelvic fins smaller, with about 10 rays, opposed to the dorsal fin, which is nearly median and comprises about 18 rays; anal fin behind the dorsal, longer than deep, with 20 rays; caudal fin slightly forked. Scales large and uniform, pectinated and serrated, not deepened or thickened along the course of the lateral line.” Identified by oilshale using Woodward, 1901. References: Agassiz, L.

    Small Mosasaur Tooth

    I've been quite busy lately but I managed to get out on October 30 and drove up to check out the W.M. Browning Cretaceous Fossil Park in northern Mississippi. Despite the high water levels I did pretty well and also found this small mosasaur tooth. I'm aware of the difficulty of identifying isolated mosasaur teeth but figured I'd post it anyway in case anyone experienced with mosasaurs or this area can narrow it down even to subfamily. Plioplatecarpinae? This comes from the Demopolis Formation which is late Campanian. CM scale
  16. From the album: Fossil Amber and Copal: Worldwide Localities

    Select pieces of cretaceous (mid-Campanian) amber from North Carolina, weighing roughly 0.7-1.5g each; most pieces found from this locality only weigh under a couple grams, which is typical of most U.S. deposits. Along many portions of the Neuse river, south of Goldsboro, the embankments expose the various members of the Black Creek Group: the Bladen member overlies the older Tar Heel Fm., and underlies the younger Donoho Creek Fm. To date, amber has only been officially described to occur in the Bladen member, and is believed to be of araucarian and/or cupressaceous origin.

    Dinosaur Claw from North Carolina ?

    I have found this claw from a site in Eastern North Carolina which has maastrictian and campanian material. Does anyone know if this is dinosaur ? Some dinosaur material has been found here in the past. Or is this crocodile or turtle maybe? It has the blood grooves on each side, unfortunately the tip is broken off. It is slightly hollow with an oval cavity. I tried to capture as much detail as I could with pictures. Thanks for your help.
  20. I purchased these as Ingenia yanshini which I think became Ajancingenia, which then became and is currently Heyuannia. The formation provided is the Djadochta Formation, but that doesn't seem right since Ingenia/Heyuannia is not found there as far as I've checked. Unfortunately, there isn't provenance other than Mongolia attached to them to say whether they come from the Barun Goyot Formation where Heyuannia yanshini is found. While I'm not necessarily doubting the original ID, I just don't really know. I'm not expecting a positive or diagnostic ID to the genus level, but I wanted to at least know whether or not I can label this to Oviraptoridae indet., possibly Heyuanniinae indet. The original ID is a bit of an odd one, but it might have just been one of the few oviraptorids described at the time. Last I checked, there are now tons of recently described oviraptorid genera in Mongolia and China. The pair of phalanges with supposedly the semilunate carpal attached which I think is the smaller section? I know one of them did have glue in-between them when I lightly smeared it with acetone using a cotton swab. They are associated coming from the same sandstone block, apparently along with other shattered phalanges. Although I don't know if these actually came from the same animal since one looks ever so slightly larger. There is some sort of clump of sand or crystalized piece attached, as well as light beige or cream colored matrix. Not sure if that narrows down a formation, probably not, but I do see a lot of matrix from Mongolia tend to be red-ish color similar to the Kem Kem Beds. Any input is appreciated. There's probably a lesson to be learned here . . .

    rudists to see

    Hello, my wife and I went to Charente to meet uncles and aunts that we had not seen for several years. A few kilometers from their home, walls and old houses in a hamlet are built with recycled materials: rudist fossils !!! here are some photos (on the first, it was not the cars that threw the fossils ) We walked through the surrounding countryside but the vegetation covers the ground, and only a corn field and a walnut plantation left some bare land where we found mostly broken pieces, but in the end a nice coral and 2 decent rudists for our pleasure. Enjoy. (I think @FranzBernhard in particular will appreciate ...)
  23. Hello, several weeks ago, I presented a rudist recovery "operation" from the Afling-formation of the Gosau-group of Kainach (Upper Cretaceous): Well, the same day I have discovered the rudist zone featured above, I have also discovered a rudist zone about 100-200 m stratigraphically deeper. It is confined to an about 1 m thick, very dark limestone bed rich in various rudist and echinoid remains. The limestone belongs to the Geistthal-formation, considering the limestone is still located within the sequence with some red clastic rocks, suggesting strong terrestrial influence in some layers. The limestone can be traced for at least 500 m along strike; at the footwall, it develops gradually from a conglomerate, in the hangingwall it is sharply overlain by fine-grained sandstone to siltstone. Here is a schematic map of the area, including also the Trochactaeon-bearing zone. In this post, I am dealing here with the "Liegende Rudisten-Zone". 59 = Geistthal-formation; 54 = Afling-formation, squares are 2x2 km. The fossils stick firmly to the limestone. But there are some impure zones (sandy-silty) within the limestone, where, with the help of some weathering, some fossils largely free of matrix can be found. Two zones of this kind are known at the moment, a natural outcrop in the forest and an outcrop at a forest road, which will be presented here. Approaching the outcrop (well, that pic was taken after the dig...): The outcrop was completely overgrown at the beginning, and this was the third day of working at this outcrop. You can see the worked area and the area prepared for today. The red x are markers placed above wooden marker sticks and about 1 m apart from each other. The soft zone between the hard limestone beds is visible. Sorry for the rather poor pics, my scrappy camera had a hard time dealing with that kind of lighting (clear sky and full shadow). Detail of the area to be worked today, still with vegetation: Vegetation cleared, first rudist found, a fragmentary Vaccinites, below the left red x. The pen is 13.7 cm long. Work in progress, "two" Vaccinites discovered. Only after some time I recognized, that this is a bouquet: Work practically finished, another Vaccinites discovered (4963). Turned out to be one of the nicest so far: Beside these Vaccinites, a few Plagioptychus aguilloni were also found in that area. But what to do with the rudist bouquet? Leaving in the outcrop or recover? I decided to recover, because it was already a little bit loose and already broken in several parts. And a one of a kind find until now. Here is the recovery, P.a. denotes a Plagioptychus aguilloni, numbers indicate individual Vaccinites specimens: The recovery ended in 8 fragments. I numbered them to help reassembling them together. This bouquet appears to be in live position, but this can also be by pure chance. Maybe closer examination with give some hints. That´s the outcrops after the work of this day, with the position of the specimens featured above indicated and before their recovery: If you are interested in the other days at this outcrop, have a look at this: 05/22/2021 (link to my homepage, in German, pdf, ca. 2.9 MB) 05/30/2021 (link to my homepage, in German, pdf, ca. 5.8 MB) From this few meters of outcrop, I have recovered ca. 10-15 Vaccinites, 5-10 Plagioptychus aguilloni and several radiolitid rudist until now. A great surprise was one large Trochactaeon snail intermixed with all the rudists (see link to 05/30/2021 above). I don´t take all fossils with me, about half of them I am leaving at the outcrop, so only approximate numbers. In the pavement of the forest road below the outcrop, I have also dug out about 15 Vaccinites specimens. Then there is the outcrop within the forest, which yielded also at least a dozen Vaccinites, still with a lot of potential. And all the other outcrops of the rudists limestone that I have not checked out in detail yet for loose rudists. Also still a lot of potential there and still a lot to do.... Hope, you enjoyed !

    This is my first attempt at getting a Dromeosaurus albertensis tooth from Judith River fm. I've largely been avoiding buying dromeosaurids like the plague that aren't Acheroraptor or Saurornitholestes. Provenance: Hill County, Montana The tooth is repaired, and I had to realigned it while restabilizing it with butvar. The tooth doesn't seem to perfectly fit together, or too much butvar ended up in-between. There does not appear to be any serrations on the mesial edge, and it doesn't appear to have any trace of serrations, at least not that I can see with a macroscope. I don't think it's Saurornitholestes sp. due to the serrations not having the distinct hooked shape. I'm not 100% sure whether or not it's Tyrannosauridae indet., but I don't think it is, but the robust dromeosaurids are supposedly very similar at first glances. Any help or clues is appreciated. If any pictures are insufficient, I can try and take better photographs.
  25. Hello! Having discovered some new rudist occurrences in the lower part of the upper Santonian - lower Campanian clastic-marine Afling-formation at Römaskogel hill near Kainach, western Styria, Austria, about 6 weeks ago. Here I would like to present a very specific visit to one of these sites at 05/15/2021. It was aimed to recover some more parts of already known rudists from the outcrop at site #30. Here we go! Approaching Römaskogel, the hill in the middle. Its 1006 m high, the snowy mountain in the background is the Gleinalpe mountain, nearly 2000 m high: Already near Römaskogel hill, again the hill in the middle. These meadows are much steeper than they appear in the pic: Location of the rudist outcrop along a forest road: Rudist outcrop, scale is 1x1 m. The rudist-bearing zone is about 80 cm thick and tips gently towards south to southeast. Individual conglomeratic rudist-bearing beds are separated by layers of siltstone. The whole extensions of the rudist-bearing zone seems to be at least about 300 m, with about 5 outcrops and indications known until now. This is the best outcrop discovered so far. Right part of the rudist outcrop. At the lower end of the scale, the next pic. The digging spot of this day is to the left of the pen: Rudists ("Vaccinites Rö1") in conglomerate in the outcrop, diameter is about 5 cm: The digging site as left at 05/06/2021 and found again a week later at 05/15/2021. I had already recovered two parts of #4901 and one part of #4910. The soft siltstone in the footwall of the rudist bed clearly facilitated the recovery of the remaining parts from the relatively hard conglomerate. The pen is 13.7 cm long: Intermediate stage of recovery. The rudists are orientated parallel to the bedding plane. They are flattened, the two big ones lying with the flat side on the bedding plane. The smaller one is orientated "on edge" to the bedding plane: Here is a primitive, highly schematic and out-of-scale sketch of the situation. #4901 and #4910 are also oriented antiparallel: Dig site after removing all the rudists. #4901 yielded two more fragment (total of 4), with the very last tip still remaining in the outcrop. #4910 yielded also two more fragments (total of 3, completely recovered). #4914 recovered in two fragments: Right part of the rudist outcrop after recovery of these three rudists. Notice the difference to the start of the recovery : Here is the complete specimen #4910. It consists of 4 fragments, that were already naturally broken. Uppermost part was found 05/01/2021, next part was found 05/08/2021, lower most parts are from 05/15/2021. The rudist is strongly flattened (about 1:2), as most of the specimens from this bed, and about 21 cm long. I don´t know the species yet, working name is "Vaccinites Rö2". (Remember, nothing was known in that area until about 6 weeks ago.) The shell has a flame-like structure, which can be nicely seen in the naturally weathered transverse section. These structure corresponds to the fine longitudinal striation of the shell. Otherwise, the rudist is smooth without any ribs. In the cross section, the P-pillars are barely visible to the right, the L-pillar is not visible: Not much time was put into this recovery, most of the day was spent prospecting an area nearby. "Discovered" a freshly widened forest road (actually as wide as a good highway!) which perfectly exposes the mostly alluvial and reddish Geistthal-formation and the following clastic-marine Afling-formation for some 100 m thickness. Not much was found, but its a very, very impressive section. Here is my prospecting area (Römaskogel is in the lower left corner) and route (in blue) of that day. Red R indicate the last (highest) reddish beds: Still a lot to walk and observe during my next trip, especially to the east of the already explored area.... You never know what you will find. For example, #45 and #46 are small Trochactaeon indications. But these will be followed up next spring, when the green has gone again. Or not at all . I only made one pic during prospecting, that of a thin (1-2 cm) seam of subbituminous coal withing silt-claystone, located between conglomerate beds (#47). Such occurrences are well-known in that area: So, that was quite a typical day in the field for me: Some collecting at known sites, but more prospecting for new sites! Thanks for looking and your interest! Franz Bernhard
