Pathological Tooth?

Recommended Posts

HoppeHunting

This tooth was found on my most recent trip to Purse State Park. I believe it is a Mackerel Shark tooth, Cretolamna. I think this may be my first truly pathological tooth because it does appear to be deformed. The crown of this genus does not typically slant to one side so much as this one does. Also, the crown is twisted rather than flat, much like the crowns of Physogaleus contortus. The thing that most leads me to believe it is pathological, however, is one of the cusps. The first cusp seems normal, but the other is twisted at a 90 degree angle and seems pressed against the crown. Can I get any confirmation that this tooth is in fact pathological? Also, can I get an ID as far as species goes, or is Cretolamna sp. the best I can get? Thanks in advance!

It does look like it has some deformations.

I do not know the genus of Your tooth, but many sharks posterior teeth are slanted more than typical anterior or lateral teeth.

Others will know better than Me.

You may be correct, as I also see distortions in the tooth, especially in the last image near the cusp. Not certain though, because as is with Tony, I am not very familiar with the genus.

Nice find! I say probably a patho, if it is indeed a sand tiger (which I believe it is), they tend to only bend slightly but mostly just get smaller as you get to the posterior positions. Carcharias Taurus teeth below.
