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 :)

Hi everyone. My name is Sonny and im a fossil collector from the Netherlands. I got into this hobby as a kid, but now with a stable income and my own house I decided I would take the hobby more serious. Since March I began picking up high quality pieces, with my main focus being anything reptile or dinosaur related. All the fossils I own are checked for authenticity, unless stated otherwise. My main pieces right now: A 3 egg hadrosaur nest from China A high quality keichousaurus from China High quality megalodon tooth from Florida Branchiosaurus with a fish on the same matrix A travertine crab from Turkey 3 charcharodontosaurus teeth from Morocco And some cool ammonites. I have more, including a unidentified reptile skeleton on matrix from Utah and theres a museum quality turtle fossil coming soon. Im looking to learn more, im not as knowledgable on some fossils and im looking to slowly expand my collection. Hope I get to know some of you better! With kind regards, Sonny

Hello, first time poster here and novice about fossils in general. I just have some questions about a broken charcharodontosaurid tooth I saw on another thread here. To my untrained eye, parts of the interior appear crystalline. If that’s the case, I’ve never heard of anything like this. If not, I’d love to know what I’m actually looking at. Original thread: http://www.thefossilforum.com/index.php?/topic/118674-big-spinosaurus-tooth/ Thanks in advance!
