Earlier this year I bought this case from IKEA for about $60. Then I added some LED lights and a few nice fossils. Check it out: Top row is basically the "ferocious fish" level Next down is the Tylosaurus / platycarpine mosasaur level Then the Cretoxyrhina level And a Pteranodon wing cast I made Overview of the four layers: Top level: Xiphactinus and Protosphraena. Note embedded tooth on r. Xip vertebra.

Hi all. I have just joined the forum so sorry if I get anything wrong! This fossil is a (I think) Cretoxyrhina shark tooth embedded in a giant ammonite. I found this on Hunstanton cliffs and it is from the Cretaceous deposit of the ferriby chalk formation. I have heard that these kinds of fossil records about prehistoric shark's diets were reasonably rare and can be of scientific interest. I was going to contact the natural history museum of Oxford if it is but couldn't find out how to so I decided to come to you guys first. The tooth is 1cm in length and the ammonite is 38 cm (15 inches). Also if anyone knows how to contact them please do say. Thanks, Harry

From the album: Cenomanian Shark Teeth and other Marine Fauna, Ryazan Oblast, Russia
Cretoxyrhina vraconensis. I believe this is a lower anterior, but I could be mistaken. -

Cretoxyrhina vraconensis (C. denticulata according to Russian literature). I believe this is an upper anterior. -
Sold as Cretalamna, it is from the Tambov Region of Russian. Cenomanian. I found this to be an interesting tooth though I am not convinced the ID is accurate. @Chase_E has a gallery of teeth from this region and a couple of other locations from Cenomanian Russia. Using those posts as a guide, I believe the tooth may be a Cretoxyrhina, perhaps C. vraconensis. I see quite a bit of similarity with a couple of Chases teeth but I am using one as comparison in this post. I could be, and probably am, wrong about that assessment lol Any input is welcomed !!

I’ve been working on getting all of our shark teeth properly identified so I went back to a few teeth from the Demopolis Formation. These are from the Frankstown location in Mississippi. The first one up is right around 1” and the little cusps are what initially confused me. Is this a Cretoxyrhina perhaps? I found some images of Cretoxyrhina with cusps that looked similar.
