I received these very strange Triassic nodules from Madagascar,an opinion about the ID? Half nodule,i think it's not a fish skin on it,Pehaps a claw?

Is there anything odd about this Saurichthys?
quam_fossilium posted a topic in Is It Real? How to Recognize Fossil Fabrications
Is this correctly identified as a Saurichthys? Does it at all seem augmented/modified? Anyone have an idea of the typical value of a fossil like this (without using the sold price as a reference)? -
I collected a number of these as a kid some 50 years ago. Only one is like this. I just thought I should try and identify it. I had always assumed it was a small tree trunk. Seems to match pictures of a calamite trunks (a new thing to me) with the distinctive ties at regular intervals. It comes from the old mining town of Brownhills UK. Coal, sand and clay were mined there. This came from the edges of an open pit clay mine. I went back to the site a few years ago but it's reclaimed now. You could still dig small holes and find fragments. So my kids found some. You just needed a bucket of water to wash the rocks off to see if they had anything because of the clay. This piece has a diameter of 4".

I find skulls one of the most interesting pieces of fossil you can ever own. So here I'd love to see all of your fossil skulls, or parts of one. Here is my Pleistocene era skull of a Ursus arctos. An ice age brown bear. Very very uncommon find.

On Friday I made a visit to an Atlanta area gem/mineral/fossil show. Generally I have poor luck at these shows, in large part because there are only a couple of dealers with fossils. This trip was different. One of the dealers was selling some items from an old collection. Most of what I bought was exciting to me because they are species I have wanted for a long time, for one reason or another. First up is a nice (to me at least) New Jersey Tiassic coelocanth, Diplurus newarki (I think the genus might have changed but Diplurus is OK for now). The dealer thought it was just a skull so it was very cheap, as the rock is very black and it was hard to see the skeleton in the room lighting. I used the flashlight on my phone to give oblique light and was very happy at what I saw! He also had some ammonites I was excited to see. Two are Triassic, a Ceratites nodosus and an Acanthoceratites spinosum from Germany. I collected a Ceratites when I was a kid (about 10) living in Germany, but it broke and all I have left is a piece. I've wanted a better specimen for roughly the last 50 years! I started to clean out the inner whorls on the Acanthoceratites but that will take quite a while. There was a third ammonite that was labeled as another Triassic species, but when I got home I recognized that it is actually a Placenticeras, a Late Cretaceous genus. I am not sure of the species and the preservation is different from the North American sites I know about, so I suspect it might be from a European source. I'll post more photos in the Fossil ID thread to see if anyone recognizes it. I also scored a trilobite I've wanted forever, an Elliposocephalus hoffi. Not because it is especially pretty, but because it is representative of the Chechosolakian Cambrian that is so important in trilobite lore. I also grabbed a nice Calymene celebra. Last up for now is an OK shrimp from Lebanon. The body is all authentic, but I'm not 100% sure about the appendages. It's pretty nice though so I like it. There are a few other little things but the above is enough for now. When I got home a box of New Mexico ammonites from the Christmas auction was waiting for me, which made a good day even better!

Triassic Tooth from Redonda Formation, labelled as possibly Postosuchus
DarasFossils posted a topic in Fossil ID
Hello, I bought this tooth from a popular fossil selling website where it was labelled as 'Postosuchus?' but the description says it is from the Redonda Formation which has not had a Postosuchus formally described from it. I'm aware there a few other species from this formation that are also pseudosuchians and could have a similar type of tooth, which I do not mind if it is one of them. Although, I absolutely love Postosuchus as a creature and I hoping that is what it is, though I know it's definitely unlikely. From my research, I assume it's Redondasaurus but this particular site has several other teeth from this formation specifically labelled as Redondasaurus so I assume there is a reason why they labelled this one and a few others differently. I've seen small teeth like this labelled as Coelophysis but I know that's extremely unlikely because it's not recurved but if it was that would be super cool! I don't have the greatest lighting equipment in my house to take pictures of it, but I can provide some shotty ones if that would be helpful! The tooth is 0.74 inches long, so quite small. The picture below is from the website I bought it from and it shows the detail much better than a photo I could take. Please don't be afraid to disappoint me! I just want to know what this tooth is!

Yesterday I set out to a site that exposed the Gettysburg formation up in Maryland in hopes of finding some Triassic footprints. What I came back with was mostly some trace fossils and burrows, but some of these looked suspiciously like tracks, so I wanted to post them on ID and see if someone with a little more experience could help me out. I’ll also probably send some emails out in hopes of getting someone who’s more experienced with the Triassic formations around PA and Maryland. Anyways here are the potential trackways I really hope to get some light shed on these and learn more about this era around Maryland because I’ve been doing a lot of research on these. Some really cool burrows: I collected the Triassic burrows in case my potential footprints turned out to be duds so that I wouldn’t come back completely empty handed. These are really cool I’ve come to believe that the small holes are where bugs or Beatles must have lived inside them. Someone with a little more expertise could chime in though. Now here’s the potential trackways. As always, these are some of my favorite fossils to collect so I REALLY want them to be trackways. But if they turn out not to be, then I will keep searching. I’ve got more leads further away in Pennsylvania but it’d just be nice to find them in Maryland where they’re so few and far between to find up there. These look fairly suspicious so I’ll see what y’all think of these. This one looks like a small theropod print, the way the traces are done. potential trackway circled. This one is also suspicious. There’s no discernible trackway to spot here, as this could just be geologic and be an inclusion in the rock, however, it could very well also be a trackway. Whether these are dinosaur trackways, or just fossil blobs that are getting me excited, I can’t help but be in awe at this site. Anytime I go to any potential trackway site, I just imagine all the small dinosaurs, early mammals, and large amphibians dominating this once river plain, leaving behind their footprints in the mud to be found. Were they running towards some unsuspecting prey item? Were they running away from something? Or just having a leisurely stroll during this time period? I don’t know what fascinates me so much about trackways but I always feel they have a story to tell about them.

I went on a recent fossil hunt in North Carolina looking for the cow branch formation. I found some fossils. It was a very quick stop, about an hour before I had to leave. I found what I believe is to be a footprint it reminds me of a tremnospondyl but it’s from the cow branch I believe. I also found some shells there, plant material, and pieces of what looked to be good footprint material but I wasn’t there long enough to fully examine. So here’s the finds from yesterday: Total haul: footprint in question: outline of footprint: What species was this footprint from? It’s late Triassic and I’m pretty happy to be finding footprints again these might be my new favorite fossils.

Please show me your casts, replicas and fakes of Keichosaurus
FranzBernhard posted a topic in Is It Real? How to Recognize Fossil Fabrications
Quite regularly, questions turn up about the authenticity of Keichosaurus fossil specimens. Until now, most, if not all, were natural, but mostly just very poorly prepped. Would you like to show off "real" fakes, casts or replicas of Keichosaurus? I would like to get a feeling for them, at least from pics. If there already exists such a topic somewhere else in the forum, please put a link in this topic. Thank you very much! Franz Bernhard -
From the album: Triassic
Revueltosaurus was a Pseudosuchian, on the branch of the Archosaurs more closely related to the Crocodilians than the Dinosaurs. Despite the serrated teeth, it is thought to have been herbivorous.-

From the album: Triassic
From the "dawn" of the Dinosaurs, this small tooth represents an early theropod. Unlike the other serrated archosauriform teeth present in the formation, this tooth is ziphodont - thin and labio-lingually compresed - the archetypical tooth form that most theropods adhered to since their beginnings.-

Lungfish are an ancient group of fish, with swim bladders that evolution co-opted as a kind of "lung," allowing them to breathe air. This may have proven invaluable in a seasonally dry climate in Pangea.-

I've found this vertebra in a Middle Triassic marine formation in the middle east. it's 29mm long. a friend of mine suggested that it's a reptilian vertebra but I want to know more. I'll appreciate any help you can offer.

What caused the decline of the Eugeneodontids - (Buzz saw sharks)
Joseph Fossil posted a topic in Questions & Answers
I've been fascinated with the Eugeneodontids (the buzz-saw chondrichthyans) and how they managed to practically become the apex predators of most oceanic environments from the Carboniferous to the Permian with famous members like Edestus and Helicoprion. Two genus of this extraordinary group even survived the Permian-Triassic Extinction 252 Million Years ago - Fadenia and Caseodus! http://www.fossilworks.org/cgi-bin/bridge.pl?a=taxonInfo&taxon_no=34456 http://www.fossilworks.org/cgi-bin/bridge.pl?a=taxonInfo&taxon_no=34451 But by the Olenekian stage of the Triassic, the group disappeared. I can understand why the more specialized members of the group like Helicoprion went extinct (ecological specialists and top predators don't do well in events like the Permian-Traissic Extinction event), but what caused the extinction of Fadenia and Caseodus? What occurred in the Triassic that ended the reign of the Eugeneodontids? -
Is the fossil site at Union Wash worth going to? I've read that the site's been depleted of fossils. Is that true?

Hello, I've had a bit of difficulty getting a possibility of what this bone could have come from. It seems far too large to be from Pachystropheus rhaeticus so could Plesiosaur or Ichthyosaur be a possibility? The bone is broken off around the back. There's quite a lot of other things aside from the bone, which I think some of include a small tooth from Birgeria acuminatus as well as one from Lissodus minimus and a scale which looks like those of Gyrolepis albertii. Thank you

Is this just a poorly prepared Keichousaurus or fake?
Muffinsaurus posted a topic in Is It Real? How to Recognize Fossil Fabrications
I bought this Keichousaurs recently from the auction site. The pictures were a bit blurry, but I couldn't bring myself to ask for better pictures because of anxieties, so I ordered it so I could take pictures myself. It arrived yesterday and to me it looks real and just very mutilated from the preparation. However, I don't trust my own assessment on such matters due to being very new to collecting. If it is fake I have until the 4th of October to return it. This is why I'm asking. So is this real? (I hope the pictures are good enough, I had to borrow my wife's camera and I spent about an hour trying to figure out how to use it. If I need better ones I can see what I can do with mine, I just don't have a macro lens)

Hey everyone, I'm new to the world of fossil hunting, and I think I may have found something. Could someone help me ID this? I don't know if it even is a fossil. It looks like it could be a plant stem or something. It is long and tubular and branches off in places. I found it in a clay pit in the Deep River Basin of Chatham County, NC. The rocks here are said to be from the late Triassic. Any ideas?

Hello together, its been some time since I posted a model, and there are quite a few unfinished ones in the making. realizing how small Atopodentatus' iconic head was in relation to its body, I decided to rather try and print a lifesize skull than a complete downscaled skeleton. Morphing recent species' skulls has the advantage that you get anatomically looking detail, although on the other hand it is wrong detail. So I would much appreciate feedback when you spot something particularly wrong. @pachy-pleuro-whatnot-odon? And Atopodentatus took some morphing. Here is how far I got: Best Regards, J

BVP Fieldschool to Poland (09/07/2022 - 17/07/2022)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone! I have just returned from a fieldschool to Poland which was organized by the BVP (Belgium Society for Paleontology) in association with the Universities of Opole and Gdansk. The fieldschool started on the 9th july and ended on july 17. The first 2-3 days of the trip took place in the historic city of Gdansk which lies by the Baltic Sea where the main focus was on Baltic Amber. This included lectures, workshops, a small museum tour and some trips to the beach in search for amber. For the 2nd part of the trip we travelled to the south towards Opole and more specifically the Jurapark and digsite in Krasiejow where we had multiple lectures, workshops, and fieldwork in both Krasiejow and other quarries in the area. So in this topic I wanted to make a day by day report on this amazing trip and experience. Since we travelled by car I only returned yesterday evening so most of the finds still have to be photographed/prepped so expect them somewhere at the end of this topic (which might also take a few days to complete.)

I've found a fossil in a middle Triassic formation that a friend of mine suggested that It's a shark tooth but I couldn't find anything similar. Maybe some of you can help me with the ID? It's 7mm long. It's pretty flat and if it is indeed a shark tooth I think that the root is missing. Thank you!
