cuvier sympheseal?

da f0ssZ,

I was looking at your Lee Creek finds, specifically the right top photo, and noticed a particular "tiger" tooth. It's the first tooth in the third row. I found a very similar tooth on the same day as ya'll visited the mine. I showed it to Becky Hyne, and she just indicated that it is
"just a cuvier".

If you compare it to the other large G. cuvier teeth, it has a thinner, nearly-contortus-like blade, with a distinctly different root. The size, though, is reminiscent of cuviers, as are the shoulder serrations. Is it a sympheseal perhaps? Or another species of tiger? I've only seen these two teeth like this.

Pictures and size would help. Descriptions just don't cut it with these things ya know?

RE: cuvier sympheseal?

hi Paul,

I don't actually have a picture of mine, but da fOssz has one in one of his trip reports. If you go to the "Trips" page of this website, then scroll down to the 9/26/04 trip for da fOssz, look at the upper right photo (the one showing fOssz' better tooth finds), the tooth in question is a larger Galeocerdo in the third row, first tooth on the left. You'll note that the blade and root are more compressed than the others. Your thoughts?

RE: cuvier sympheseal?

Keith:

I put the tooth in my "caseworthy" tigers and have it in front of me now. Taking a closer look sparks my interest as well. I noticed I have one other tiger tooth like this (from a Pliocene site in SC). What appears different to me is the bulbous portion of the root at the center region. Most of the "cuvier" teeth in my collection have relatively flattened roots

I need to check out a dentition of a modern shark to see what a sympheseal looks like.

Also, I will try to put up some pictures of these teeth for continued discussion.
