My First Tooth! Thinking Scapanorhynchus

Recommended Posts

I found this tooth and got SO EXCITED! I am still learning and starting this hobby, but very fast becoming addicted! So far all I wanted to find was a shark tooth and after finding two Ptychodus whipplei teeth, I saw this!

I am thinking Scapanorhynchus. Found in North Dallas with other Cretaceous fossils.post-12443-0-63879600-1374539847_thumb.jpg

Might that be an example of Cretoxyrhina mantelli instead? I could be wrong but the root looks like it. And I don't see the prominent striations running the length of the blade like you have in Scapanorhynchus? I have attached an image of one of each side by side. The black tooth is the Scapanorhynchus.

One question please...were you by chance poking around in the Kamp Ranch Member of the Eagle Ford Group? It is characterized by slabs of a yellowish limestone many of which contain a phosphatic layer of pebbles and teeth. They sometimes even contain fish vertebrae or plesiosaur teeth.

It may very well be Cretoxyrhina, all suggestions welcomed! I found it where there is a lot of red and orange mud clumped into softer rocks, with layers of grey. It was loose and washed to a waters edge. Sorry, I am not too familiar with the formations yet. :(

With quick research the tooth you suggest is also curved, like the one I found. On the back side it is grey (no lines) and very smooth.

What is the difference you see on the root of the tooth?

I believe the Cretoxyrhina root is thicker. It is also a little wider. And there is a really pronounced grove in the middle at the base of the Scapanorhynchus root. At least this is my belief...

When photographing shark teeth for identification, it makes it easier if you shoot it straight on with views of both sides. Sometimes, a profile view helps so we can see how prominent the lingual protuberance (the root bump) is. judging from the photos, I think it is a Cretoxyrhina mantelli.

Here is the back side.

Thanks for the tips, I will try to take pics of the "profile" and post again.

Here are pics from the sides. Also the second tooth I found (missing one side of the root bump). Both were found at the same location.
