I found these two vertebrae together in the Dinosaur Park Formation of Alberta. I’m wondering what they might be? I’m suspecting rather Champsosaur, turtle, or juvenile theropod. Any insight into the identity of these two elements would be great, thanks! @Troodon

I found these two vertebrae nearby each other in the Dinosaur Park Formation. I originally thought it might be Champsosaur, but after closer examination I ruled that out. I then thought salamander, but the neural canal on mine is too small. Finally, I thought it might be a lizard (like Paleosaniwa), but the vert itself is more slender then a lizard vert. So, I’m out of ideas. I’m wondering if it may be from a juvenile theropod, but I really can’t tell. Any help would be appreciated. Thanks! *should note on the vert with the majority of the process preserved that the ar

Is this a partial skull? (from Pennsylvanian Shale; northeast Oklahoma)
Gramps posted a topic in Fossil ID
I found this broken nodule in an outcrop of Pennsylvanian shale in Northeast Oklahoma. I’m wondering if the fossil could be the upper part of a skull? Other common fossils from this site include fragmentary fish remains (e.g., teeth, spines, dermal denticles, and coprolites from sharks and other fishes), as well as invertebrate remains from ammonites, gastropods, bivalves, brachiopods, corals, and conularia. If this is a skull, would you guess it to be from a fish, amphibian, or reptile? I don’t see any traces of teeth in the nodule, but I can provide closer views of areas that might be o- 48 replies

One night recently I was hiking with one of those high powered spot light apparatus on my head and while looking down I noticed this specimen. Not sure if its a fossil or from what type of creature it came from but it definitely struck me as quite interesting and out of place. Does anyone have any idea what this could be?

Hello, This is the proximal head of a fossilized femur that I bought a few months back at a rock shop. The only collection info I know is that it’s from Florida, and by the looks of it it’s probably from the Peace River. After doing some amateur study I’m pretty sure this is the end of a horse femur, though of course I have been very wrong before and so would like some more thoughts/opinions. Unfortunately the place where the third trochanter would be is broken off which makes identification more difficult. Many thanks!

Hey there! New user, and probably not likely to stick around for long if I'm honest. I've just never had much of an affinity for forums, I'm afraid. That said, I have been absorbed by this particular specimen for several decades. The only suggestion I've heard so far is some kind of whale, but I was curious if I could narrow it down a bit more. Also, I'm not an expert, but it seems pretty different from most whale vertebrae I've looked up. That said, there are a lot of bones in a lot of kinds of whales out there, so I could easily, easily be wrong in my skepticism. This

Team collecting Eastover: Heavy on pics. Whale, shark, fish, etc
sharkdoctor posted a topic in Fossil Hunting Trips
For several years, @Gizmo and I have been working to grow a collection of vertebrate fossils from the Eastover formation for the Calvert Marine Museum and for our own study. We've developed a wide range of stream sites along the central Atlantic Coastal Plain and have collected a variety of vertebrates ranging from pinnipeds to fishes. This summer, @WhodamanHD and @HoppeHunting joined us to tackle some of the more difficult sites. Below are some bits and bobs from our trips this summer. This was a team effort so we thought it might be fun for this post to be a collective effort as well.- 63 replies

Its a solid specimen with interesting internal structure. Does not look like bone. Maybe section of horn sheath or body armor?

I found this fragment of a fish fin during my last trip to the North Sulphur River. The ribbed structure looked so much like a piece of tile that I almost walked past it at first! I've been looking at some of the photos in the Dallas Paleo Society's book on the NSR since I've been back, and the closest match I can find are the pectoral fins of Protosphyraena tenius. The only other thing I can think of is maybe part of the tail fin of a Xiphactinus audax? If anyone has any suggestions, they'd be much appreciated!
