  1. Another trip to the Catskill formation and more fish. This time it was new sites on Rt 6 in Pennsylvania and some of the sites visited before. During the Middle Devonian, the Acadian orogeny had uplifted the edge of the tectonic plate and created a very high mountain range to the east over New England and down the east coast (ref1). These mountains eroded rapidly and much of that sediment was carried west toward the inland sea that covered PA and NY. The Catskill delta shoreline raced westward across the northern part of Pennsylvania in the Middle to Late Devonian. Marine sediments were replaced by near shore fresh water and then flood plain deposits. The Catskill represents this deposition and in this environment the first tetrapods evolved in a very diverse and complex ecosystem. So it's interesting to examine the spatial and temporal relationship of the deposits. Most of the work so far has been done at Red Hill and along Rt 15. So I had read about a Tristichopterid jaw that was found in the road cut along Rt 6 at Wyalusing Rocks and wanted to take a look. That site was a little disappointing but another road cut east of there in Laceyville, PA produced this interesting and almost complete but poorly preserved jaw. And after some reconstruction. The plates above the jaw appear to be some kind of head plates but because of the poor preservation I have yet to see any ornament. There are teeth in there and I will attempt to expose them when I get to my new house in Connecticut. and the counter-part More to come
  2. Mammal Jaw? (Location unknown)

    Hi all, First time using the forum. I got this from a local rock and mineral show years back, but they gave me no information other than that it was a “prehistoric deer.” Using this, I did some research, and highly suspect that it could be the jaw of a Leptomeryx species (which would put it somewhere in N. America?). It definitely resembles the pictures I’ve seen. Any and all help would be greatly appreciated.
  3. I have a specimen of a shark jaw that I am unable to identify. From a quick search, it seems that it might be a snaggletooth shark jaw, but I am not completely sure.
  4. I can’t figure out if these are 2 associated jaw pieces. In most pictures they sure look it, but some pictures make me second guess it, and if they aren’t, they’re definitely still the attaching pieces, even if from different animals. I was looking at it backwards for awhile, which set me back, but I figured out the thicker part is actually the front of the jaw, right before the curve, or right after it starts, if it’s been glued on at the incorrect angle, which I think could also be possible. the 1st picture looks very strange because of how that smaller section suddenly drops down and gets taller, and especially strange after researching and finding out that it’s supposed to get wider there, but actually SHORTER. the 2nd picture looks good, except it MIGHT supposed to start slightly curving inward at the point of reattachment pics 1,3,4,6,&7 all make it look like they rent supposed to be associated together, but the other pics make it look very accurate. I don’t know what to think, so I thought I’d see what people with much better knowledge than I, think about it.
  5. Basilosaur lower frontal jaw section

    From the album Marine reptiles and mammals

    Basilosaur(us?) frontal lower jaw seyction, from Boujdour, in Morocco. Hopefully the species can be distinguished with some more info
  6. Basilosaur frontal lower jaw section

    From the album Marine reptiles and mammals

    Almost the entire frontal canine portion of the lower jaw of a Basilosaur. As you can see, the area where the absent front canines were, at the tip of the piece is visible, as well as where the missing last canines were situated. Although it was labeled as a Basilosaurus, I’m a little hesitant to consider that the case until I can personally corroborate the information. Apparently from Boujdour, I’m just having trouble finding information about which whales are, or are not found there, so until then I’ll leave it more open with just Basilosaur.
  7. Bone Identification - Botswana Skull

    Hi everyone, Can you help me identify what animal this may be? It was found in Botswana. It is a semi-arid climate. Any idea if it's carnivorous or not? Any clues are helpful! Thanks.
  8. Good day everyone, I'm looking into these two partial mammal skulls: An oreodont Merycoidodon and a Camel Poebrotherium. I'd like some help to find out if these are all real or have been partially fabricated, enhanced, composited, total fakes. Photos 1-4: Merycoidodon culbertsoni Oligocene Nebraska Photos 5-8: Camel Poebrotherium labiatum Brule Formation Oligocene-Whiteriverian Converse County, Wyoming
  9. Mosasauroid Jaw

    Hi guys, I have recently acquired this Mosasauroid partial jaw. Seller claimed it is a juvenile Mosasaur. He acknowledged that some of the teeth may have been reattached. But he didnt know which, he got it from his supplier like this. And upon further questioning, he also admited that he is not absolutely sure about the genus. He speculated juvenile Mosasaur due to its size, but i dont think a smaller genus of Mosasaur, like Halisaurus, Tethysaurus or Platecarpus, is out of the picture. Please help me identify the genus of this Mosasuroid and the location of this jaw (dentary or mandible, left or right). If you would be so kind, please also point out to me, which teeth are wrongly attached, or maybe, composite. (The 3 red arrows are the teeth that felt quite real) Thanks. Edit: Almost forgot, seller claimed it came from a Phosphate deposit at Khourigba, Morocco.
  10. L.S., Since animal fossils are definitely not my strongsuit, I would like to call upon the incredible collective knowledge here at TFF and ask your help with the identification of the fish remains shown below. This specimen comes from the Westphalian D (Pennsylvanian, Carboniferous) of the Piesberg quarry near Wallenhorst, Germany. The shape of the scales reminds me of images of rhizodont (?) fish scales, but this could very well be a superficial resemblance only... Penny for your thoughts? Kind regards, Tim
  11. Possible theropod jaw fragment?

  17. Woolly Rhinocéros teeth or...?

    hello folks, I recently acquired a series of 3 teeth identified by the dealer as belonging to Coelondonta antiquitatis (woolly rhino) from 'Russia' (whatever that means). The teeth are certainly from the rhino family (that's as close as I can personally get), but these particular teeth are huge, t least twice the size of any other woolly rhino (or Teleoceras sp. ) teeth that I have (sample size about 20), or any scaled photos of woolly rhino teeth and jaws with teeth that I've found online (note: lots of photos available online, few with scale, alas). I've include two photos below showing the teeth, and a tape measure for scale. Two additional photos follow that include a woolly rhino jaw with teeth and a separate tooth for comparison to these three It got me wondering if these aren't from a woolly rhino but another member of the family?. In scanning the Asiatic rhino family tree, Elasmotherium sp. (Pleistocene) and Paraceratherium sp. (Oligocene) are the only two that exhibit a notable size difference from ol' Woolly. Unfortunately, there are maddeningly few images of teeth or jaws from these two animals, and nothing with scale that I can find. Thoughts? Any references to recommend? thanks in advance!
  18. Hello everybody So this fossil here bothers me for some time now because I'm still not sure what to make of it. I'm especially asking for the roots in the jaw and if they are a composite. Also this one tooth growing out of the root of the root looks odd to me. Is this a genuine fossil or are these roots / tooth put in the jaw? I'm used to these fake teeth put on jaws as a composite form Morocco but with this one I'm still not sure what am I looking at. On one side you can actually see the root in the jaw. Would something like this be fabricated as well? And is the ID correct? It's described as a partial maxillary of an Elosuchus sp. from the Ifezouane Formation, KemKem from Taouz/Morocco. No word about any restoration/fabrication or what so ever. Size is 3.48 in (8,84 cm).
  19. Pliosaur jaw

    A rare pliosaur jaw with part of tooth unfortunately it's weathered tooth and it's measures about 4 inches and incomplete its could be larger what's a monster it would be. Its from Jurassic, Kimmeridge Clay. Dredged from the Smallmouth Sands off Weymouth Harbour, Dorset
  20. My wife found this piece of jaw bone on the beach while on vacation last month at Topsail Island, NC. At first I thought it belonged to a shark, but upon closer examination, the tooth doesn't resemble any of the hundreds of shark teeth I have found in the past. Any help identifying this fossil would be greatly appreciated. Thanks
  21. This is a find from Big Brook, NJ. Its about 15mm long and 10mm wide at the end. Could it be a salmonoid Jaw fragment? Like these http://www.njfossils.net/salmon.html

  23. Morocco crocodile????

    This is a “pterosaurs” jaw I got as a gift a little bit ago. It was sold as a pterosaurs jaw with composite teeth the species is Siroccopteryx But Am almost 100% sure that it is wrongly identified it looks like a crocodile jaw maybe. So if someone can help me identify the jaw that would be amazing. It was found in the kem kem beds and is 2.3 inches long

  25. Mosasaurus or Croc

    Found this yesterday while hunting with the family, in Big Brook. Can't tell if it's Croc, Mosasaurus, or something else. I forgot to include a ruler in the pictures, but the fragment is about 5 inches in length. Any help on how to safely remove the green sand stuck to it would be greatly appreciated.
