  4. Season Start

    Last weekend I started my collecting season 2013 after this long winter. I was fortunate and found some Lower Carnian ammonoids. Hunting again is a very good feeling.
  5. Five Islands Provincial Park [2012]

    Taken from my recent blog post: http://redleafz.blogspot.ca/2013/04/five-islands-provincial-park-2012.html Here's another of my belated posts on one of my trips last year. Me and my buddy Craig went for one of many trips to the beautiful town of Parrsboro, Nova Scotia. From town, we headed East towards the small village of Five Islands, which has a Provincial park of the same name: Five Islands Provincial Park. Islands from right to left: Moose i., Diamond i., Long i., Pinnacle i., Egg i., Pinnacle rock Five Islands Provincial Park is a location that has witnessed several events, including a major extinction. Most of the rocks South of the park, towards Red Head and continuing on to Lower Economy, are of a red sandstone from the Triassic Period. These red sandstones from around Red Head are indicative of an arid, desertic climate. On top of the Triassic rock is a layer that corresponds to the Triassic-Jurassic boundary, sandwiched between Triassic sandstone and Jurassic basalts right on top of it. This Triassic-Jurassic layer is identified by its white sandstone and mudstone. The importance of this layer is that it represents one of the major extinction events that had occurred at the boundary. It is still being studied today. The basalts that top these sandstone layers South of the park and protrude West and created the islands, are of the same found at Blomidon and Cape d'Or. These Jurassic age ancient lava flows and dykes could have been part of an active volcanic network seen all over the Minas Basin. The Old Wife is a result of this contorted, violent past. The islands which dot the landscape are also mostly composed of this Jurassic basalt, and some sections of Jurassic sandstones. "Old Wife", with Moose Island in the background The red cliffs just North of the basalt and separated by faults is of Jurassic age. Dinosaur tracks and other fossils have been found occasionally from either the cliff face, or from loose rocks on the beach. A local by the name of Eldon George had found, among many other wonderful fossils, the smallest dinosaur tracks ever found back in the 1980s at Wasson's Bluff, sandstones of the same age and formation not too far from here. See Jon Tattrie's article. Organic layers within water channel Jurassic McCoy Brook Frm. (left), Jurassic North Mountain Frm. (right) But I digress, as I keep rambling on the technical and less on the practical. We arrived at the park when the tide was going down. We walked down the beach and was met with a thick band of fog that was going out the bay. Lava flows Heading South after searching the beach for agate and fossil fragments, the fog lifted and the Sun came out. We went around the Old Wife and headed towards Red Head. Fault running through columnar basalt Beach made up of basalt and minerals "Red Head", seperating the Triassic-Jurassic Blomidon Frm. (West) and Triassic Wolfville Frm. (East) Triassic Wolfville Frm. red sandstone cliffs Modern day trackways (crab) This area is only accessible at extreme low tide, so the window of opportunity is very small. Getting trapped or stranded is a very highly probable so good planning and looking up the tide charts before heading down this way is an ABSOLUTE MUST! This is one of the places in Nova Scotia that I highly recommend visiting, among other sites of course. =)
  6. Dinosaur Park, Laurel Md

    I recently went up to a place named Dinosaur Park, in Laurel Maryland. Mostly triassic aged stuff. The place was originally set up to be an iron mine, and the minors started digging up bones. This location is famous for the discovery of the Astrodon a large Sauropod. The images I have inserted are pictures of carbonized pieces of fern. In more common terms, it's coal. Roughly 120 million years old coal. Some of the coal still has iron traces on it.
  7. Economy Point (Copequid Bay)

    From my blog: http://redleafz.blogspot.ca/2013/04/economy-point-copequid-bay.html Back in August of 2012, I took part of a walk organized by the Fundy Geological Museum (FGM). It was in the middle of the week (Thursday August 9th, I think), so there wasn't any tourist or non-employee beside myself. The gang consisted of geology students and staff, led by Ken Adams, the curator of the FGM. Looking out towards Cobequid Bay Economy is located in Nova Scotia, East of Parrsboro in Cumberland County. From Parrsboro, you take the 2 road and head East, past Five Islands Provincial Park. Economy Point has many trails that are beach accessible, but the getting there can be messy with the muddy silt snaking within the bay. View of Five Islands (background) The rocks of this area are part of the Wolfville Formation, Triassic aged red siltstone and desert sandstones, a lot of it apparently sculpted by wind. The bottom part of the cliffs along the bay are of this red sandstone, and upon it rests several feet of glacial till from the last ice age that helped sculpt the area. Moving around entailed hiking up and down huge slabs of sandstone that displayed odd physical features. There are all sorts of trackways and burrows, but there are also structures that none of us could readily identify. Burrows? Plant traces? Toolmarks? Triassic sandstone (bottom), glacial till (top) Diplichnites (such as of a myriapod)? Natural caves Water channel Bird nests in the cliffs The further East we walked, the stranger the physical features would get. Even Ken was baffled by some of the structures we'd come across. Here's a few photos taken by my Blackberry and you be the judge. Can you identify any of the following? Bottom of a tree (?) Tree roots (?) Many of the structures are found on this red sandstone Worm burrows? These holes are so odd. At first I thought they were cavities left behind by plants, but some of these exhibit strange patterns around, looking bizarrely like projectile of some sort. Some of these 'projectile' show patterns and/or direction. Am I imagining things? After a long and hot afternoon, we turned back and made it back to our cars, pondering on what we saw. We were intrigued by what we had found. Was this unique? If not, where else could we find these? Any feedback would be much appreciated! =)
  8. Upper Tuvalian Ammonoid Fauna

  9. Triassic - Lockatong Formation - Montgomery County - Pennsylvania This is another piece I collected March 2 at the Triassic Lockatong site I was exploring. The rock is a totally different color and the black marks on the pinkish rock are interesting but seem to be too indistinct to be fossils. My impression is that these are simply mineralizations and traces but since I've never seen these before I'm posting them here. These are natural light photos that show the pink substrate: These were taken with incandescent light: In technology innovation (which is my profession) we talk about "weak signals" indicating trends and innovations that are just beginning to appear. My few Triassic visits have been focused on some very fossil-poor Triassic formations that run like thin ribbons through Montgomery and Chester County, PA. I keep wanting to return to our fossil-rich Devonian and Carboniferous sites that are 1 to 2 hours away but the proximity of these sites (10-15 minutes from our home) makes it easy to spend an hour or two exploring. The trace fossils and few fish scales that turned up so far suggest that something more meaningful will eventually appear. This weekend Nan and I also found a very large flat rock with what appear to be lizard tracks but they were eroded into round circles - arranged in track patterns, and one has a sharp toenail type point - not worth collecting but another weak signal that keeps drawing us back to these sparse Triassic formations...
  10. Triassic Lockatong - Plant or Root Fragments? Saturday I spent 2 hours looking over a Lockatong formation (Triassic) in Montgomery County, PA. I'm sort of testing my ability to spot some fossil patterns in this formation where fossils are very scarce. I found this interesting piece with lots of organic fossils and impressions - assume they are plant fossils. It's so difficult to find Lockatong fossils in PA, anything we find is interesting. I've included a piece of the large rock (about 10 inches) and several closeups. These look to me like some sort of vine-like plant stems with rootlets and also cross-sections of stems. Also on Saturday, Nan and I visited a second nearby Lockatong site and saw what appear to be reptile tracks on a piece of rock about 4 or 5 feet long - although the impressions were round and not track shaped except for one of the round impressions had a thin pointed tip. We did not photograph or collect this, mostly admired it and count it as a "weak signal" that there are better fossils to be found.

    Upper Triassic Ammonoid chunk with Trachysagenites sp.(on top with nodes) and other ammonoid genera.
  12. Lockatong Trace Fossil

    Happly Holidays to everyone and all the best for 2013... Here's a trace fossil from our last Fall fossil trip - Lockatong - Triassic - not sure what this pattern represents. The rock is about 1 foot wide. Here are some additional photos including a shot of the full rock, and some angles that show the thickness of the trace material and may give some clues to the consistency, etc. The opinions on what this might be are very interesting - as for me, I have absolutely no clue...
  13. Tuvalian Ammonoids

    From the album alpine triassic Ammonoids

    Slab(ca.30x15cm)with different upper Triassic/Tuvalian ammonoids. In the middle of the slab a Trachysagenites sp. is visible. A Jovites bosnensis(inner core)is directly above. Below the Trachysagenites and on the top of the slab Discotropites sp. are visible. Several other Tropites sp. are visible also on the chunk.
  14. Season Closing

    Last week my friend and I went to our probably last trip this year before winter comes. We went to an old location of mine. I stopped digging there years ago because rock was the more solid the deeper we dug. Now after several winters I hoped for new material. We found less but good material. I did preparation immediatly after washing . The ammonoids are of upper Triassic, lower Carnian age. Exactly they range into the Zone of Trachyceras aonoides(=Zone of Trachyceras desatoyense in US strata) Sorry for the bad pics but light was/is not good in these grey, misty days. Andreas

  17. Wasson Bluff (Parrsboro)

    Taken from a June 2011 trip - http://redleafz.blogspot.ca I've since gone to that site so many times I can't remember. This location is as rich in fossil material as it is in minerals. Enjoy! Wasson Bluff - Parrsboro, Nova Scotia Every year the Fundy Geological Museum (FGM) hosts curatorial walks of the many sites located in the Parrsboro area in Nova Scotia. Saturday June 11th the FGM organized a curatorial walk of the Wasson Bluff located a few minutes east of Parrsboro, on Two Islands Road. I had gone only once before last Summer. I was happy to go back as I wanted to find out all the information I could get from Wasson Bluff. Wasson Bluff is a very special place, as the earliest dinosaurs have been discovered in this area. This area has seen the smallest dinosaur foot prints ever found, some of Canada's oldest dinosaurs ever found, and important signs and clues of the ever changing landscape and makeup of the Earth. The curatorial walks are free, and that weekend being tourism week, the admittance to the Fundy Geological Museum exhibit was also free. Me and my friend Craig, along with some other fellas had some time to spare before the walk, so we checked it out. It is well worth it as they have a lot of interactive games and displays, and wonderful specimens on display. By the time we were done the museum, there was still about an hour left before the tour, so we asked for directions on local eats. The friendly staff helped us by pointing out local restaurants not too far in town. We opted for one that was at the end of a street next to the museum on Pier road. The tiny restaurant, the Harbour View, was a home cooking style seafood restaurant and it didn't disappoint. The food was great and the service was good. View of the bay from the restaurant. Wasson Bluff is located further west of the FGM on Two Islands road. It takes a little bit less than 15 minutes. Here's a few pics from the walk: Getting ready for the hike. My friend Craig on the left. The welcome sign at the Wasson Bluff entrance. Hopping down the steep trail. Easier down than up as I would learn coming back up. Finally on the beach! View of Clarke Head. The tip of the cliff is darker basalt/volcanic rock. The gray/greenish-like part of the cliffs is gypsum/salt-like sediments, remains of bodies of water that vanished a long time ago. From there to where I was standing were the different faults and strata that make up the general landscape of this part of Wasson Bluff. Ken Adams, our interpreter, and also the FGM's curator. (Two Islands in the background) Close to the beach entrance you'd get these strata of sandstone and mudstone. These look similar to the carboniferous strata you'd encounter at beaches like Joggins. The sandstone show animal tracks and natural weathering. Ichnofossils (animal tracks) made by ancient animals. Cliff made up of volcanic rock. Sedimentary mud filled with clastic basalt rocks and bone fragments. Clastic basalt fragments in sedimentary silt, signs of the work of continents moving apart. Bone fragment in sedimentary matrix. The picture above seem to show sedimentary mud that would have squeezed in fractures of this volcanic rock, creating the look that we're seeing here. If I remember right, magma would have solidified (could have been underwater), and at a later period silt like mud would have made its way, filling any cavity it could propagate into. The green algae show the level of the tides. Bone fragment in Triassic age rock. In the background you have your greyish volcanic rock. In the foreground you have a mix of wind blown reddish sandstone to other types found in aquatic environment. This is the start of what they call Wasson Bluff, famous site of the many dinosaur bones, some deemed at least the oldest in Canada. The sandstone that bear the multitude of bone fragments are usually the ones that show clastic basalt, as they usually indicate some type of aquatic environment, like watering holes. From what I can remember this would have been a valley where animals would make their way. Several events happened to have retained the animals where they are, to later be unearthed by scientists. Such remains are displayed at the FGM for people to view. The Triassic rock shows cavities where animal specimens had been found and unearthed. The cliff face changes all the time, so there is always a chance to find something. What I found fascinating is that we have this type of site in our own backyard, at our doorstep. There is always that awe factor where you're thinking, some of the oldest animals have walked where you have walked. The features you can find in the earth, the traces of animals long gone, the pieces of a puzzle that help define the history of not just the locality, but the global picture of how things were at one point in time. I have enjoyed Parrsboro and I'm convinced that anybody that goes there would enjoy it. Cheers!
  18. This is my first official Triassic fossil - a tooth (or fish fin) and some associated (poor quality) tissue/bone pieces found in a late afternoon exploration of some rocky outcroppings in Montgomery County, PA. Both halves of the impression are included. The impression/cast are very faint and some of the definition is in jeopardy of being lost since the material powdered and flaked off a bit as it dried, and is less defined now than when I first brought it home and took the first images. Here are some views of the full shale piece and surrounding smooth area with a small skin or tissue fragment at the top: You can see the smooth area around the fossil "tooth or fin" in the positive and negative halves of the shale - which is medium grey in color and about 20 centimeters long. I chiseled open the shale while I was exploring a steep vertical outcropping. What led me to crack this particular piece of shale was a nearby small assortment of what appeared to be dessicated bones and fragments and the shale color was different from the surrounding red shale. I'm including images here of the "bone fragments" and associated material which appear to be fossilized organic material: This closeup has some impressions/pockets that may help with identification: . Update (Oct 23): There is a growing consensus that this may be a fish fin (or scale) - considering that this appears to be attached to a smooth section, and there is a bit of "skin" at the top left, this interpretation makes sense. I agree that I should remove more substrate to see what else can be revealed. Thanks to Fossildude19 for providing links to the Triassic Teeth chart and to a few experts I contacted off-line to get their opinion. The best thing about this find - regardless of the faint impressions, difficult ID and the crumbling possible bone and skin - is that this was found in an area where finds are few and far between, in Triassic sediments that are really scarce in Pennsylvania, because glaciers basically scraped and eroded most of the Triassic and Jurassic geological formations down to older (Ordovician, Devonian, Carboniferous) layers. I wasn't expecting to find anything and this was revealed just as the sun was going down, using the last half hour of daylight and came from inspecting an anomalous shale color in the formation. This suggests that it is worth our time to check out more Triassic formations in our home county/southeastern Pennsylvania. We are totally "clueless" about Triassic fossils (more comfortable with Carboniferous ferns) but since the Passaic and Lockatong formations are scattered in several places within 20 minutes of our home, we are making a few short trips to see what we might run across. Nancy and I remain interested primarily in Devonian and Carboniferous fossils and sites, however our first venture into Triassic territory holds some promise.
  19. 'Dawning of the Dinosaurs', by Harry Thurston, came out in the mid-90s and highlights the discoveries made in the Parrsboro region, where Canada's oldest dinosaurs were found at Wassons Bluff. Amidst the many volcanic basalt, there are these red sandstone cliffs that contain buried treasures from the Triassic. Parrsboro was also the location where the world's smallest dinosaur footprints were found by Eldon George in the mid-80s. What is also fascinating about the dinosaur skeletons are the state they are in: many have been fracture by faulting, giving them the name 'quake dinos'. Other animals of interest were some of the biggest crocodiles that ever lived! The research is still ongoing at Wassons Bluff and still yield many interesting specimens. http://www.nimbus.ca/
  20. A Weekend Visit to A Road Cut Near Our Home Nan was busy this weekend so I drove to a road cut on Route 422 south of Pottstown, PA - about 5 miles from our house. I had been told by a friend at the Delaware Valley Paleo Society that there wouldn't be any fossils here - from the geological record, I think this is part of the Gettysburg-Newark Lowland Formation which is described online as late Triassic. The shale is red with some green and gray mixed in here and there. Telling me that there wouldn't be any fossils here was a challenge I couldn't resist. So I decided to see if I could find anything in this very barren but geologically interesting formation. What I found were fossils and impressions of a tree and twigs that resemble Siggilaria (which were extinct by the Triassic I believe), and a few other trace fossils and what I assume are some mineralizations that look like leaves but probably aren't. I wonder what kind of tree this bark pattern represents...any ideas? The roadside exposure is a very steep slope covered with golf ball sized rubble and lots of larger rock formations protruding, here and there. The roadcuts are located along Route 422 several miles south of Pottstown, Pennsylvania. I studied everything that was visible, cracking lots of rocks to see what might be hidden. Nothing, no marine fossils, not even a freshwater clam. I began to feel that this might have been a dry area, or mostly dry area. Then I came across a narrow cascade of rubble that had eroded off the steep wall and noticed some red shale pieces that looked like smooth bark of some kind. On closer inspection, I discovered several pieces (many were fragmented) that turned out to be a grooved bark pattern. In the first fossil (1.1, 1.2 and 1.3 with backview and closeup - see below) you can see: a) the bark pattern which resembles Siggilaria including one branch node (the round circle) and you can also see at the top where the bark ridges begin to branch into a diamond shaped pattern. Although this is supposed to be a Triassic formation, the tree bark has a Carboniferous look, but I'm not familiar with Triassic trees. Here are the images of the bark sample: BARK 1.1 BARK 1.2 BARK 1.1 Back View BARK 1.1 CLOSE Bark 2.1 and 3.1, and Fossil 4a(front) and 4b (back) - These are additional samples of what appear to be bark and branches/twigs: BARK 2.1 BARK 3.1 FOSSIL 4a Front FOSSIL 4b Back Twig 5 - Here is what appears to be a twig and twig impression: TWIG 5 Not sure what this is: FOSSIL 6 I assume these are mineralizations (dendrites) that look like leaf impressions but are chemical, not fossils - note the shale color is different from the red shale above (labeled Mineralization 1 and 2): MIN1 MIN2 Anyway, I guess my point is that I visited a road cut that is close to home, easy to access, and where I was told there should be no fossils. I found quite a lot to look at and ponder, and best of all, despite being parked on the roadside for 3 hours, I wondered if I would receive a visit from curious police but not at all so I felt very comfortable, except for the times when I climbed some very steep sections and found it a bit tricky to make my way back down the steep crumbly slope (I got down by choosing a section that had small samplings and used those as grips on the way down). I'm still not sure what else might be here or at other roadcuts but I have a hunch that this must be what fossil hunting in "dry" tree and plant areas might be like, since all the sources claim that not many dry forests were preserved as fossils because there wasn't much mud in the dry areas and they almost needed to be buried in a rockslide or freak flood to be preserved. Paleobotanists also suggest that the fossil record is heavily weighted toward wetland plants and trees so anything that comes from what was originally "dry" forest or meadow is worth inspecting.
  21. I bought this specimen many years ago on an exhibition. It was labeled "Saurichthys" (100 % wrong). All I know is that it's from the Karoo Supergroup of Madagascar. Since the Karoo Supergroup spans a lot of time (upper carboniferous until lower jurassic), it makes it especially difficult to asign the fossil to the "correct" order or family of tetrapods. I don't think it's possible to identify the genus, but I would be glad to know the order. araucaria1959
  22. Had my husband drop myself and Bella the Labradoodle off near an area I had heard there were fossils. I walked down to the cliff and a piece had eroded out. It was full of partially weathered plant fossils, which I am fairly sure are Dicroidium, a Mesozoic seed fern. There was also a seed/cupule that I have posted in the ID thread for an accurate appraisal, check it out, it's gorgeous and shimmers in the light! Ok I will stop gushing now, here are the pics XD
  23. Triassic Seed/cupule?

    Found this gorgeous little fella today in some Triassic sediment that had eroded out of a cliff near here. It was in a layer that also had a lot of Dicroidium leaves. I thought it might be a cupule, just looking for an accurate ID. Cheers,
  24. Picked this strange looking item out of a gray mudstone/shale layer within the Narrabeen Group (second picture). Should be Triassic in age. It broke into 3 pieces as I removed it but inside was a beautiful arrangement of black, white and red minerals. It also has small round 'nodules' on the left part (seen as the small dark circles), and appears to have 'veins' on the right. Any thoughts on what it is would be greatly appreciated. Cheers, Susan
  25. Here are a couple of finds from the Southern Highlands. The rock is very fragile and the fossiliferous layers are incredibly thin. Most of the material I've found has been fragments, but these are the nicest bits. I believe the second one to be Dicroidium cupules. If anyone is interested in this site or the fossils feel free to PM me.
