Hi everyone, I brought a small collection of hell creek digits and claws, and wanted some help with identification. They come from Garfield county and are mostly small. Appreciate any help and thanks a lot ! first is a tiny claw, theropod or bird?? Measures about .375in second one looks like a theropod claw? Maybe dromeosaurid or struthiomimus ? .5 inches third one is a little over a inch, maybe pachy/thesce? 4th one not sure what species 1.25inch 5th one 1 inch. Turtle? 6th theropod? Dromeosaurid? Troodontid? 1 inch 7th a 1.25inch digit not sure what species. again thanks for all the help, I’m not very comfortable with identification of digits and claws yet :).

Thankfully, Morocco offers Theropod Teeth at reasonable prices. They are quite attainable. These 2 teeth, were sold as; Spinosaurus Sp., and Carcharodontosaurus Saharicus. I am aware, that the Spinosaurus tooth has likely been repaired. I believe the Carcharodontosaurus tooth, has not. Hopefully, these id's are correct?

Hiya everyone. Want some opinions on this egg it’s from an old collection and from a reputable seller in the uk. I know a lot of shell is missing but any help on the legitimacy of the egg would be great. cheers

I am tempted to bid on one of these, I haven't got a a portuguese tooth yet. I was wondering if anyone is able to narrow down the species. Tooth 1 14.5mm x 6.8 x 3.7 Tooth 2 - 6.5mm x 3.3 mm, x 1.9 mm thanks for the help

Found this week, recalling the info troodon taught me some time back this appears to be theropod material. Wondering if anyone can help me narrow down anything else, maybe what part of the animal & if possible (if it is theropod) whether it’s tyrannosaurid or ornithomimid, as far as theropods in the area that’s all it could be at this size. dinosaur park fm

Every year at the Denver fossil show it seems like I pick up some unidentified Kem Kem material. This is because for one it’s cheap, but also because it’s kinda fun to investigate this material. Here are eight pieces I picked up as a bulk set. I have some idea about identification on each of these but would love to hear other’s input. In the following pictures I have the top row being archosaur fossils and the bottom row being fish fossils. My guesses: 1. Caudal(?) vertebra centrum. Croc or theropod, but probably croc. 2. Croc dorsal vertebra 3. Croc centrum 4. Theropod pedal phalanx. Specifically, the distal-most phalanx of toe 1 (the “dew claw”). Narrowest ID I think I could guess we would be Ceratosauria indet., should probably be labeled as Theropoda indet. 5. Two fused fish vertebrae. Are these identifiable any more than this? 6. Gar or gar-like vertebra 7. Chondrichthyan fish vertebra. Maybe Onchoptistis numida? Can that determination even be made? 8. A gigantic ganoid scale. Any guesses just based on size? I’m unfamiliar with all the monster fish in this rock unit. Thanks :)

From the album: Hell Creek / Lance Formations
This rare theropod tooth was found via screen washing matrix from a channel deposit. It's large for the species and from the front of the jaw. All of the denticles are intact - a spectacular specimen. Pectinodon (meaning "comb-tooth") is a tooth taxon, since no remains attributable to the genus beyond teeth have been found. Pectinodon seems to be a rare member of the Hell Creek fauna, with their teeth being fairly uncommon (though being so small, I'd guess that few people actively search for them). It was a small Troodontid theropod, with teeth that couldn't handle stresses as well as their Dromaeosaurid and Tyrannosaurid cousins (Torices et al. (2018)). This coupled with their small size suggest that Pectinodon was a small/soft prey specialist, preferring the rodent-sized mammals of the time, lizards, insects, etc. Some researchers have proposed omnivory as a possibility for Troodontids (cf. Holtz et al. (1998)). Troodontids famously are regarded as among the most intelligent dinosaurs for their large brain size / body size ratio. This notion serves as fodder for speculation that had the dinosaurs not gone extinct, Troodontids (Pectinodon being (one of?) the last) would have continued to grow in intelligence and develop sentience and civilizations. Troodontid teeth like Pectinodon can be easily identified by their small size, exaggerated, triangular, apically oriented posterior serrations.- 1 comment

Collages of dinosaurs made with pictures of fossil teeth
BirdsAreDinosaurs posted a topic in Paleo Re-creations
This is a fun project that I have been working on for the past few months. Fossilized dinosaur teeth from the Kem Kem beds in Morocco showcase a wide variety of colours and patterns, caused by the varying conditions under which they were fossilized. To me, these colours and patterns are rather beautiful. Therefore I decided to ask a colleague of mine, who is a professional photographer, to take pictures of my small collection of teeth, so I could use these pictures to create collages of the original owners of the teeth. Using this approach, I made images of theropods from five different families. The animals on the images inhabited what is now known as Morocco about 100 million years ago. Here they are. The white bar next to the teeth represents 1 cm. This one I based on the species Spinosaurus aegyptiacus. This one is based on Rugops primus. I was inspired by the patterns of the Gila monster. Based on Deltadromeus agilis, which might be a noasaurid. As no skull of this dinosaur has ever been found, I am not sure that these are actually teeth of Deltadromeus. The other side of the smaller tooth shows an interesting white pattern, caused by plant roots growing on the fossil. Based on Carcharodontosaurus saharicus. I am not certain that these teeth are dromaeosaurid, but they do have characteristics that indicate that they might be. I love the pattern on the smaller tooth, which made it pretty easy for me to create a feathered look. I went ahead and got cards printed with the collages on the front. On the back I have included the family names and the specific teeth I used for each collage, at full size! It was a fun and refreshing experience to try a completely different approach to making illustrations.
