Cool North Texas Finds From The Pleistocene And Cretaceous

Recommended Posts

Texas Fossil Hound

I was poking around in a Texas site looking for my very own Mastadon Molar, with which CreekCrawler has so recently shamed us all. I did not find any elephant parts, but I did find a pretty cool Pliestocene Equus tooth - cheek tooth I think. Does anyone have a link to a good Pleistocene/Oligocene/Miocene Mammal tooth website or a good reference book?

This is the most complete Globidens tooth I have found - about 75% there. Most of the back is missing unfortunately. :wacko:

One Crab that may have a pincher intact. I will explore the matrix later.

Happy fossiling! :D

The Equus tooth is a lower cheek tooth and is likely Pleistocene. Unfortunately, trying to identify an isolated horse tooth as to species is practically impossible in most cases. Lower horse teeth (except the P2) are always rectangular in outline while upper cheek teeth (except P2) are basically square in shape. There are a number of articles available on-line and I have links to many of them in the section on horses in Fruitbat's PDF Library here on TFF.

Cool finds! Are you sure your Globidens isn't a gator tooth? Seems too conical for a Globidens...

I am not 100% sure, but there are 2 aspects that make me think Globidens over Gator. One, the pinnicle of the tooth dips inward slightly and it does not appear attributable to wear. Secondly, the orange peel texture is present. I have seen samples of Globidens that are slightly conical, but I am totally open to debate. I would like to hear more opinions.

I, also, have the impression that this is a crocodilian tooth; but, I'd want to see more of the tooth to be more confident.

Here are more comparison images:

Here's an image of posterior croc teeth that was posted by 'Geofossil' in a long-ago thread (I thought some of 'em resembled Globidens teeth).

Hmmmm. Tough call on this one. Do the croc teeth have any kind of orange peel texture to them? I have not seen many of them.

I have a crab that is very similar to the one you found. I have not ID'ed it yet. Let me know if you get an ID.

My came from the Arcadia Park formation in the Cedar Hill area. Do you know what formation the crab came from?
