  1. 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?
  2. Florida Fossil Femur Head - Equus?

    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!
  3. Carolina Coast Vertebra

    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!

  7. Body Armor?

    Its a solid specimen with interesting internal structure. Does not look like bone. Maybe section of horn sheath or body armor?
  8. 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

  10. Cretaceous Fish Fin

    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!
  11. Some Sort of Jaw?

    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!

  14. Shrimp's collection

    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.

  17. Unknown Humerus

    I found this distal end of a mammalian humerus several weeks ago on the Brazos River southwest of Houston. After hours of searching, it doesn't seem to exactly match any of the common suspects: deer, camel, horse, or bison. Deer or camel is more likely than horse or bison, as the bone is relatively slender and the end of it isn't as bulky as either of those animals. It is possible that I have incorrectly ruled out deer and camels as the trochlea and capitulum on the end are very worn down. If anyone has any suggestions, I'm more than willing to hear them. Thanks!
  18. Perissodactyl Astragalus

    Both of these astragali were found on the Brazos River southwest of Houston. The larger of the two clearly belongs to Equus, but the smaller one continues to stump me. I know by the shape that it definitely some sort of perissodactyl, and although it resembles the shape of the Equus astragalus it is much, much smaller. The taller of the two ridges (I'm not sure what their name actually is) on the proximal end of the bone has been worn down by water or time so that it seems almost level with the other. If it were still present, these two astragalus would probably be identical. It occurred to me last week while looking at it again that it might be from a three-toed horse since they were a lot smaller than the more modern species of horses that prevailed in the late Pleistocene. Is there any way to tell? Or is it just from a younger Equus individual? Thanks for the help!
  19. Oligo-miocene micro tooth

    I was lucky enough to receive some Micromatrix from @Gizmo and @sharkdoctor, and today I was looking through some of the teeth when I saw one I hadn’t noticed before. I’m sure I’ve seen something like it onlin but I can’t for the life of me remember where or what it is. Any one got any ideas? Matrix is from VA, Old Church FM (oligocene) and Calvert FM (Miocene) contact layer. Measure is in centimeters
  20. ID Florida Vertebrate Fossil

    Hello, East Venice, FL vertebrate mystery fossil. Unique indentation in V shape. Found in Pleistocene material. Cracked by tractor. Recent material identified in same location as: Sloth, Equus, Meg teeth. I realize it is not the best specimen but the V shape on one side is unique. Thanks in advance for your suggestions/identification. I didn't see an example in the gallery or textbook. Height is 5cm
  21. The winner of the June 2020 VFOTM goes to... Placoderm fish (Cowralepis mclachlani) - ~385 Ma (Middle Devonian); Merriganowry Shale Member of the Dulladerry Volcanics - Central West NSW, Australia Congratulations to @Paleoworld-101 !!!
  22. Mystery Jawbone

    Found on the Brazos River just southwest of Houston. When I first saw it I almost left it behind as it looked modern at a glance. The jawbone is definitely mineralized, however, but unfortunately its missing the teeth it used to contain as it's only one side of the whole bone. My best guess is that its a fragment of an alligator jaw based on the round tooth cavities and the way they're spaced apart, but if anyone more knowledgable then me could give a suggestion, that would be great.
  23. Shark Tooth Found

    I found this tooth at my normal overburden site, at work, it is the best shark tooth i have even found. Looking at Shark tooth I.D guides my guess is that this is a Auriculatus tooth. What do you all think?
  24. Placoderm material from New York?

    Found this nice slate blue piece in my recent trip to Western New York. What do you guys think? The piece isn’t very big, maybe half an inch - but it looks relatively thick, maybe a centimeter and a half?
