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.)

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

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?

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!

Hi there. I have this Triassic tooth from the Bull Canyon formation sold to me a good few years back as belonging to Coelophysis. I'd tentatively labeled it cf.Coelophysis (due to the locality) but now that I'm going through and re-evaluating everything I'm not sure it is an accurate description considering the curvature (though I'm not knowledgeable on ontogenic variation in this genus). I'm aware of a great thread posted by Troodon about this particular area but I'd like some input on the possibility it could belong to other Archosaurian taxa. My knowledge of this area is minimal so I'd appreciate any help. I counted about 26 denticles/5mm on both carinae.

Are these fossils? And if so, what of? Found under Seacliff Bridge in New South Wales
spagbutcher posted a topic in Fossil ID
Hi everyone! I'm new to fossil hunting and I found a few interesting rocks underneath Sea Cliff Bridge near Wollongong in Australia. There was a lot of coal in the area for context. I will attach some photos of the rocks I found, I'm particularly interested in the small white (quartz??) lines intersecting the black part of the stone. Any help would be hugely appreciated! Thanks

Trackway paper presented
RetiredLawyer posted a topic in Partners in Paleontology - Member Contributions to Science
Hope this isn’t inappropriate for this forum. For everyone who was following my excavations, Dr Klein presented his findings. Dr Lucas is coming back later this year to pick up a few more tons of my tracks.

Here is a tail of a marine reptile from the Triassic period. It was found at Fuyuan, Yunnan Province of China, at the same strata with Keichosaurus. Does it look like the tail of Yungguisaurus liae or Placodus inexpectatus? It is 56cm in length.

Selling Real for Fake Fossils?
Lucid_Bot posted a topic in Is It Real? How to Recognize Fossil Fabrications
Everyone I've encountered on this site has been very helpful, so thank you. However, I'm in need of more help. For the last year I've been collecting real fossils in the field and selling some to pay for more exotic rocks. In a recent post I found that my Solnhofen shrimp is, if not totally, mostly fake. Now I'm quite suspicious of my entire purchased collection and was hoping you could help me identify fakes. The first two pictures are apparently Priscacara, Green River Formation, Eocene; the next two supposedly Asteroidea, Morocco, Ordovician; the last three supposedly Triassic, Arizona petrified wood--this came from the same group that sold me the fake shrimp. All help is appreciated.

Spiny bivalve from Upper Triassic limestone at Aust Cliff, Gloucestershire, UK
Georyx posted a topic in Fossil ID
Hi everyone, First time posting here so please forgive any dodgy formatting. I found this bivalve shell in the Upper Triassic limestone beds at Aust Cliff, Gloucestershire, UK. I posted this on Reddit and only one person managed to have a guess at a Ctenostreon bivalve genus, but they are not sure. The spines on the edge of the shell seem a bit too evenly-spaced out in my opinion. (By the way, the grooves surrounding the shell are from where I've engraved the fossil a little. I don't have the equipment to fully extract it, so I have no idea what the outside of the shell looks like). Thanks all - any help would be appreciated. - Georyx

The Mesozoic is an area that is sorely lacking in my collection. I don't know why, but I just never got around to collecting in it. I never fell in love with dinosaurs or mososaurs like a lot of other people. That was until fairly recently, when I finally took it upon myself to diversify my collection and get to know better my area's (and in some ways own backyard!) geology and paleontology. I set out to discover more about Maryland's Mesozoic Park. I guess it would be best to start off from the beginning. I started the journey not knowing what I'd find, but knowing what it was I hoped to find. I wanted a piece of the hallmark of the Mesozoic, the age of reptiles - my very own Old Line State dinosaur! There was only one problem - I didn't know where to find one. I knew generally what formations to look in, but not where, nor even what to look for. So I took up the ole' Google machine and my own literature at home and started uncovering more about where to start looking. That's what lead me to the first site. A TREK INTO THE TRIASSIC It would be disingenuous to say that I did this all by myself, and I would like to thank @WhodamanHD for helping me out tremendously. Without him I likely never would have gotten this together. For those who don't know, I'll take the liberty to describe the geology of the Free State. In Maryland, the only Triassic aged rocks exposed are those of the Newark Group, here divided by the Maryland Geological Survey into two formations - the New Oxford and the Gettysburg Shale. Both units are exposed in the Culpeper Basin (centered around the town of Poolesville, Montgomery County, Maryland) and the Gettysburg Basin (centered around, in Maryland, the town of Emmitsburg, Frederick County, Maryland). After several months of searching I was never able to find a good exposure near the famous former quarries around the Seneca region in Montgomery County, which is what lead me to the area near Frederick. Here the Triassic rocks are more readily exposed, with reports of numerous fossil discoveries of dinosaur footprints, plants, fish, and others in the area near Mt. St. Mary's University and Rocky Ridge. The Gettysburg Shale in this region is the most fossiliferous, and that is the one I ended up collecting in. Thanks again to @WhodamanHD for giving me info about the site! I spent a good hour or so at the Gettysburg Shale site, my mind full of images of that amazing Grallator sp. print I'd know I'd find. Unfortunately, as the shadows started growing and the day grew colder, I was forced to give up my quest without any dinosaur specimens from this unit. Still, it was nice to finally be able to collect in it and get to experience these amazing rocks up close and personal. The vast majority of the finds from this site were simple trace fossils of I assume to be annelid worms, these being most common in the glossy looking shale.

Anyone have any Southeastern PA triassic track site localities
A.C. posted a topic in Questions & Answers
Hey all, I am really interested in finding some of the southeastern PA track fossils. I realize it is a huge stretch to ask for a locality but figure it is worth a shot to see if anyone wants to share information over PMs regarding locations or other useful information on this area. Thanks in advance! -
