Unknown Cretaceous tooth

Recommended Posts

I’m pretty sure this is an xiphactinus tooth but I’ve never seen one that’s fully rooted before so that’s what has me questioning my original thought. I have several X-fish in my collection but all appear to sheds or broken off where the root would’ve been. I found this tooth last Sunday on a bar where I’ve found 10-12 other X-fish. It was found in the Blufftown formation of Alabama and is 1-5/8” long, 5-16” wide. Any thoughts or comments would be greatly appreciated!

I think you are correct with your ID.  I've never seen a rooted one and my searches did not pop any up.  I did find this article which shows them in a jaw.  Hopfully someone can do better.  Very cool find, congrat.

Looks like Xiphactinus to me too.

Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday!

Thank you for the comments everyone! Here’s a pic of the other little guys I’ve found on this same bar. 06A6913C-D4FE-4C64-812E-A0197B00E7C2.thumb.jpeg.f3fc136781d36bb14ccab0017b8dbd34.jpeg

Wow, that is exciting. I have never heard of or seen an x-fish tooth with the root before. Amazing condition and spectacular specimen. Congrats

Beautiful specimen. I too, have never seen one rooted.

I have been collecting Cretaceous fossils in Alabama for 30+ years . Those teeth are very similar to Plesiosaur teeth we have found in Green County . Nice fossils !

Cool find, looks like X. vetus. Here’s the only rooted one I’ve seen from NJ (their tooth is actually a vetus):
