Hello everyone. These two teeth were teeth I acquired from a fossil hunter in Russia. The first tooth is a double tipped Archaeolamna sp. The second tooth is a pathological Cretoxyrhina vraconensis (denticulata according to Russian literature). I've got a lot of non-pathological Cretoxyrhina, Squalicorax, Dwardius, etc. if you guys want to see those as well.

This was found by myself in Ellis County, TX. I believe the formation was the Atco (or at least the Austin Chalk & Eagle Ford, if I’m not mistaken). The scale is in centimeters. I can post other images if needed; these were the two I just happen to have accessible at the moment. A couple of people who saw it in person said it was Squalicorax. I have some Squalicorax that have the well-known distinctive shape, but I also know that Squalis have teeth that don’t have that angled look. I’d never seen a non-angled Squali tooth before. However, when I posted it online in a Facebook group, an experienced shark tooth collector was absolutely adamant that this is Cretoxyrhina. So now I am unsure. I am more inclined to say it is Cretoxyrhina, but I am far less familiar with vertebrates than inverts. Thank you for any help!

From the album: Post Oak Creek
Another one of my favorites, the "ginsu" shark, so named for its sharp blade-like teeth. The largest one in the center is indeed from POC, but I bought it online.-

Early Cretoxyrhina (vraconensis) dentition question
britishcanuk posted a topic in General Fossil Discussion
I’m wondering if anyone has put together a dentition of an early Cretoxyrhina with narrow lower teeth and cusped laterals and posteriors. If you have photos of something like this I would very much appreciate seeing what one looks like. Thanks in advance! R~- 5 replies

Hey y'all, this is a shark tooth I found a couple months ago in post oak creek. I initially thought it was a cretodus, but now I'm having second thoughts. The 4th and 5th pictures are cretoxyrhina vraconensis and dwardius woodwardi, respectively. Thanks!
