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 articulate surface on one side is noticeably convex.

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 of interest. I’ve done as much prep work as I dare with a brush and needle (my skills and tools are rudimentary). I look forward to any thoughts you may have. Best wishes .- 49 replies

My husband still has 7 years left in the Air Force (3 more years here in Wyoming and then 4 years at our next base). Then he’ll retire, we can move anywhere, and I can finally be done moving! I’ve gone through 7 major moves in my life so far, 2 of them to other countries. I’m beat and just want to settle down for a while. So my question is: if you could live anywhere in the US based off of fossil hunting interests and access, where would you live and why? England really spoiled me with how easy fossil hunting was, and I would love to find a place with such access and diversity. I’m mainly interested in vertebrate fossils, so bonus points if your location has easy access to those (no points are actually being awarded ).

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 was found on a beach in southeastern North Carolina, it is approximately 7 cm long, nearly 11 cm across, and almost 9 cm in height, for reference, in case the ruler is tough to read. View from behind: View from above: View from the front (and upside down): View from the side: I appreciate any help or information anyone can offer, and if nothing else, I hope you guys get some enjoyment from the puzzle! Let me know if I did anything wrong or if you need more info and I'll see what I can scrounge up to help you out. Cheers!

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

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. A whale cervical vertebra and billfish bill- 63 replies

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!

Hey Fossil Gang, I had a surprising find along Canon River in Northfield Minnesota (coordinates 44.461901, -93.158759). I was skatingboarding and noticed that the banks of the river were pretty rocky so I thought it would be worth investigating, sure enough I found what appeared to be some sort of bone attached to a piece of rock protruding about half way out of the sandy soil. To me it looks like some sort of mammal jaw although I'm not sure (new to fossil hunting). I'm not sure but it seems to be more modern. If any of y'all have any input it would be greatly appreciated!

Hello everyone I have a pretty small collection, so I thought why not share it since it would only take a few posts? First up, these are my only self collected fossils. From walking along the Humber river in Etobicoke, which puts them in the Georgian Bay formation I believe. I would love some more information! Sweet little orthocone is why I took this one home. The back of the rock which shows an imprint of somebody's shell. There may be some other stuff going on in the matrix here but I've got absolutely no idea. Another orthocone with siphuncle pic if it helps with identification.
