Mammal tooth ID please

[diginupbones]

Another new one for me. Found in cherry county Nebraska.

 

[PrehistoricWonders]

I’ve got no clue what is, cool tooth though!

[Rockwood]

Oreodont maybe ?

[Shellseeker]

Rhino?

 

 

[diginupbones]

I just noticed that my photos didn’t show the contours of this tooth  very well. These may help a little bit. 

 

[Shellseeker]

Almost certainly some Rhino type animal... Yours is a lower tooth.  Where was it found? State /Formation?

You should do a google search for "Hyracodon nebrascensis teeth"

That is very interesting! I had no idea that the early rhinos looked like that. I’ve been getting into a few areas lately where I am finding some very very old teeth that I have never seen before. I am going to tag you on another recent post of an old tooth I found and see what you think of that one.

Right,  I had no knowledge about South Dakota or Nebraska mammals or their teeth.

But I know how to recognize FLORIDA rhino teeth...  about 2-3 inches, relatively narrow enamel layers, obviously ridge at the gum line, deep valleys in the enamel,  and then saw this photo,,, What ever it was called, it HAD to be related to Rhino

I think it’s pretty amazing how many fossil mammals Florida and Nebraska have in common and so far away from each other. Especially the horses.

The average species is extant for (ball park) 10 million years. It's a long walk, but they were in no hurry.

Thanks for the reference. As I clicked on the link, it auto magically downloaded.

versus asking me where I wanted to put the pdf.  Nice

I love pictures: As I found in this fossil thread, Rhino teeth are pretty similar across the eons and around the world.  Curious

This appears to be a lower tooth.  Senile, very worn, I'd say.  It's not any of the rhinoceratids I know of.  Eliminate peccaries as a possibility.  The tooth is neither selenodont (oreodonts), nor bunodont.  I have the feeling I should recognize this tooth, but I am stumped.

What do you think about Mesohippus?

Maybe a chalicothere tooth -- Moropus is the last representative from Early to Middle Miocene.

I think the perissodactyl direction is probably correct, but the mystery tooth lacks the crochets in the enamel evident on the tooth in your images.

[jpc]

I will agree with Perissodact6yl lower molar.  Cherry County is almost all Miocene so it will be more recnt than the typical White River stuff we see a lot of here.  More similar to Florida Miocene teeth.  Of the teeth seen above, chailocothere looks most like it to me.  

[diginupbones]

I think you nailed it Harry.  What a strange looking animal! I’ve had a heck of a run on old strange teeth here lately so I hope you don’t get tired of looking at them. I’ve got a few more really unusual ones to post up but I’m trying not to throw too much out there at once! Thanks for everyone’s help.  

[garyc]

Old strange teeth are always welcome here!!

[PaleoNoel]

I certainly agree with perissodactyl as partial rhino was my first thought. I think Harry is on the right track if not spot on. 

Very cool find! I don't think I've ever seen any chalicothere material on here before.
