Okay, How bout this one? Found in the same area near Yuma, CO. same place as "The Egg Maybe" ... and the the tooth that is not a Bison tooth... but, maybe a Gomphotheriidae..
I think it looks like scale (ish) things on (we'll call it the top) and then Dermal layers on the side (YES, I polished part of this one too... okay... well, most of it... sorry)
So, here it is.... and it measures 1 1/2" x 3/4" x 1/2"
Now, be kind please.... I see cells, and cell walls... don't I, it could happen right?
...more pics on the way.
... and thanks for reading...
