Hello all. I picked up a mystery specimen. It's from the Kem Kem (Tegana Formation), ostensibly. It weighs 1.5 pounds. The skull has hollow cavitiies (air sacs?) inside, but I can't tell if they're air sacs; for arteries, or for nerves. They're definitely not mere 'holes'. I spent hours cleaning out pebbles and tiny/flat river-worn rocks and red matrix that filled almost every one of the holes that you see, so almost all of the holes were open pathways when the creature was alive. It was sold as Carcharadontosaur, but with an emphasis that it's not known what bone it is. The bone is solid/heavy, even with the open passages. The only two body parts I could think of are 1) skull fragment, but I have no idea what part. 2) A partial vert: It looks like a neural pathway that runs between a vert and the spinous processes. However, I've not known vert processes that have this shape. Any educated guesses would be deeply appreciated. Please note that the last 'image' is a video; it provides good context for orientation. I can post additional photos if that helps. IMG_2513.MOV

Authentic Kem Kem Fossils? Composites?
eurichhhh posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello! I'm a new member and I was hoping I could get some second opinions on some Kem Kem fossils I'm thinking about purchasing. I've only collected American species, and have been recently interested in bones out of the Kem Kem beds. I've stayed away thus far because of the stories of composite fossils and Frankenstein pieces, but I've come across a couple that I thought were interesting and fairly priced. Was hoping I could get some other thoughts before moving on any of them (wanna make sure they aren't composites or areas of fill look weird). I've attached pictures of three specimens I'm looking at. Any help would be greatly appreciated! 1) Spinosaurus Vertebra 2) Spinosaurus Rib I think this one is what it is, prep work doesn't look the best, but just wanted confirmation I guess. 3) Carcharadontosaurus vertebra (transverse processes) I was wondering if I could get help on confirming the id on this one, not really sure what carcharadontosaur vertebrae are supposed to be like. Centrum is missing, not sure if that's important for the id.- 2 replies
