Hi from New Member (Cretaceous vertebrates in amber)
living_amber posted a topic in Member Introductions
Greetings! I’m new to the forum, but have referred to your posts often in learning about fossils. Now that I’ve got (I hope...) a basic understanding of vertebrate paleontology, it’s time for me to start participating. My background is broadly in natural history and biology, but lately I’ve been very interested in (1) amber fossils of all ages, and (2) evolution of Mesozoic tetrapods (using Cretaceous amber fossils). I look forward to joining discussions and sharing some of my exciting dinosaurian (and even pterosaur!) finds from the amber markets of Kachin State, Myanmar. Thanks in advance for any/all helpful replies to my posts, and I look forward to meeting everyone. All the best, Christopher (Los Angeles/Chicago) -

Here's a few teeth that have me stumped from Southeast Alabama. The area they were found is right in the middle of the Tallahatta formation which should point to them being from the Eocene. We found over twenty of them in the same area with the sizes ranging from 1" to 1/4' inch long. Each tooth is curved and has deep ridges that run the entire length of the tooth, though some are worn more than others. The bases are all round which points me in the direction of a crocodile of some sort but that's where I'm getting stuck...I cant seem to find anything that resembles it online so any help would be greatly appreciated! Thanks, Terence Here's a picture of the other items that were associated with them

Hi everyone, I'm looking for a bit of help with 3 finds from this weekend that I have 0 idea where to start with (bear in mind short of crinoids, trilobites, ammonites and belemnites I've not seen very much). All of these come from Warden Point on the Isle of Sheppey, UK. Lower eocene, London Clay formation. The first was recovered from the shorefront, the last two were found in-situ in the cliff face (loose, no hammering was required to remove them). This first one looks really exciting to me and for some reasons when I saw it I thought "turtle" but truth is I have no idea where to place this. The second one looked like a tooth to me, just an irregular shape I guess. As a piece broke off I can now see the interior structure and there is a clear layer of mineral/crystalline deposit on the surface, but beyond that I can't distinguish anything. This is likely to be nothing, but still I'd prefer to hear it from someone that has a better idea. The last one is probably the most exciting and puzzling of all as it is quite large. The curved shape and striated structure of this drew my attention to it and I decided to remove it from the clay and take it home for a closer look. Turns out I was right as there is definitely a hollow structure that I was able to reveal. As to what this may be, I could only guess as a large gastropod perhaps? Your mind races to stuff like dinosaur claws/horns/etc with some of these (very mature of me, I know), but it would be really interesting to hear any guesses that might fit the location. More importantly I would really like some advice on how I could extract the fossil from its matrix as it still has quite a lot of hardened clay around it and after going at it for an hour with a toothbrush and very tentatively with a small knife trying to pry off the clay, I decided to leave it alone for fear of damaging it. Thank you in advance for your patience and any questions that might help with suggestions I will try to answer as quickly as I can (if I can :))

I just found this 7mm by 3mm claw searching matrix that I collected years ago from an Eocene site in Virginia. The site was a near shore, marine environment. I found a good number of turtle and croc fossils at the site in addition to fish, shark and ray fossils. However, I also found close to 100 bird bones of different species and several terrestrial mammal specimens. Unfortunately the specimen is not in the greatest condition. I've found lots of crab claws at the site but it is definitely not crab. Out of the possibilities of reptile, bird and mammal the claw looks like it is from a bird to me based upon the curve. What do you think? Marco Sr.

The information on Asineops is scarce so I thought I'd do some research and make it publicly available. Asineops squamifrons is a Eocene fish and an incertae sedis. They are rare and are most commonly found in a fragile layer of the green river formation at smith hollow quarry. They can be found in fossil lake or lake gosiute. Fossil lake ones are bigger but rarer. I don't know the maximum size on these but I would guess 7-12 inches. Their scales a very distinctive in shape. According to Rosen and Patterson (1969) it may represent a intermediate between acanthopterygians and paracanthopterygians (which looking at a phylogenetic chart is confusing to me) , meaning their closest living relatives would be the troutperch and its allies (percopsiformes). Its relations to other fish are confusing and not understood but it bears some affinity to Nardoichthys (a Italian late Cretaceous fish which seems to be closely related to troutperchess) and prolates (couldn't find much info on this guy). Diagnostic features include the following: long premaxillary ascending process six branchiostegals unforked caudal fin with 14 principal rays (12 branched) cycloid scales full nueral spine on PU2 two epurals free second ural centrum two anal spines two supranuerals unserrated preopercular Pelvis girdle and cleithrum do not touch unfused lower hypurals sources: Wikipedia Enigmatic fish Oilshales topic @FossilDudeCO Fossil lake Specimens from top to bottom: @oilshale Fossil lake If you have anything to add, or a specimen to show off, I encourage you to do so! Thanks for reading!
