C. catticus teeth?

I have a total of four teeth now that I have identified as catticus, three from a land site in Virginia and one from the Castle Hayne quarry in N.C. The cusplets on mine do not appear to be quite as long as the photos I've seen on DW's teeth. The roots are extremely compressed on all 4 of my teeth. One kind of cool thing about these teeth is the lingual protuberance is so pronounce that all 4 teeth naturally "sit up" in my display cabinet. That is when laid on the root, the blade sticks up in the air. If i am right on the ID then that tendency to sit up could be a defining trait for ID on these teeth. Anyone else noticed this? Ideas/comments are appreciated.

Re: C. catticus teeth?

I love a reason to go look at my teeth in the middle of the night. I have 5 C. catticus, 4 from the Chandler Bridge (oligocene) and 1 from the reject piles in Aurora. 3 of my chandler bridge teeth stood on end like you describe and 1 did not. My aurora specimen also did not up on end. However, the 2 specimens that would not stand on the roots exhibited a slight degree of root wear that probably contributed to their inability to "stand up" to the test. I also have 1 C. totuserratus from the Chandler Bridge and it stood on end. The tops of the roots are all very flat, but they are all upper teeth.

Re: C. catticus teeth?

If my dreams of finding a big meg just lying on a beach (actually came true a month ago!) waiting to be picked up are interrupted, then i often go stare at some of my old finds too. Glad to hear someone else has noticed that with the catticus teeth, that's how mine are displayed in my best finds case. This site is awesome by the way....

Well, to give credit where credit is due, I didn't notice it - you did. I just went and looked at my teeth to see if specimens from the Oligocene did it, too. I didn't even know there was a Carcharoides from the Eocene, so I learned something to boot.

Thanks for your compliments on the site. It makes me glad that others enjoy it as much as I do!

mason, yeah, I have noticed, and it is this characteristic--which is shared by the cusplets--that are the defining characteristic according to a few of the Lee Creek "old-timers" (who shall remain nameless bc they would kill me if they knew I called them "old-timers" LOL) Keith
