Hello, a friend of mine found some kind of large fossilized creature in a cave on Sand Mountain in northeast Alabama. It was buried in red clay. The rocks containing fossilized bone are broken into many pieces; he has collected hundreds of small to medium sized pieces and there are many larger ones still at the site. Most of the creature is still there. The rocks are a sandy yellow color and unusually light weight. I washed one of them (#28) and there was a lot of tiny bubbles forming in different places, showing that the rock is porous. Three of the pieces (see pic below) he assembled into a complete joint. The creature may have been 20+ feet long, and I would guess it's a sea creature, given that the imprint of a seashell is found in one of the fossil rocks. The complete archive of images is here: http://grow.game/files/fossil-pictures-lowres-2021-05-26.zip These are pics of only 32 pieces of the hundreds he's collected. Notes on individual images: #20 appears to be some kind of iron ore. It's unusually heavy. There is another piece just like it also. Could be a clue to the geology of the site. #27 note the shell embedded on one side. #28 looks brilliant orange because it's still wet after washing some dirt off. This is the one that was bubbling in different places.

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 articulate surface on one side is noticeably convex.

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!

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.thumb.jpg.f64412d7ebb21a8527dbd5e178b8366d.jpg)

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