Need help with small Pleistocene mammal teeth


Bone Daddy

Recommended Posts

On my last trip to Gardner (Peace River, Bone Valley member, Hawthorn group, Hardee County, Florida), I found these small Pleistocene mammal/vertebrate teeth. 

 

Even when these are pristine, I have difficulty with them because they all look so similar. Some of these are pretty worn, so ID might be impossible. I tried to snap good photos of the crowns to show the distinctive "squiggles". Can anyone ID these? Any help would be greatly appreciated. I compared them against photos of previous teeth I have found, but I couldn't come up with anything.

Three more, with one oddball on the end :

If you are referring to "the one on the end" being the right side, it looks like armadillo to me.

I thought "sloth," but xenarthran, for sure.  I see a lot of horse tooth fragments, as well.

Sloth may be the sensible choice.

The armadillo have more of a "figure eight" shape right?

Thanks for improving my photos. My camera is not the best. What image program or filters are you using? I use brighten and contrast filters in the GIMP photo editor, but I don't get great results like that.

 

Would there be any way to determine which type of sloth/armadillo it is? I assume it's not a giant ground sloth tooth because it's too small and the texture doesn't look right from the ones I have seen in photos. Could this be a smaller extinct sloth, or a smallish/juvenile giant armadillo?  What about glyptodont? I think their teeth look different from this as well.

 

For the horse teeth fragments - some of them do look like partials/brokens, but a couple look complete with no obvious signs of breakage along the sides. Is this my eyes playing tricks on me and they are not intact, or do they represent juvenile/small individuals? All of the horse teeth I have found were a lot larger (even the fragments).

Well, giant armadillos do have anterior peglike as well as the figure-eight teeth.  Sloths have peglike teeth, particularly the smaller species like Nothrotheriops.  Howeverr, smaller individuals of larger sloths start with some peglike teeth.

I use a free software called Photoscape.

It is extremely easy to use, and intuitive.
