It's one of the rarest pieces in my collection.

One doesn’t see material of this Coelacanth on offer very often 

Just a tail….

My rarest partial fossil is a partial Omomyid left dentary, the first reported fossil primate from the Atlantic Coastal Plain of the United States, from the Eocene of Virginia which I donated to the Smithsonian.

I’m gonna have to say either my partial Glyptodont tooth or my single cusp from a Mastodon molar would be some of my rarest finds. Mastodon obviously isn’t rare - but a complete tooth, especially one that would’ve been blue/white… oh boy.

Cool post!

 

My favorite, probably most rarest fossil I have is my Archaeotherium partial jaw. Although it is not super rare, I have heard that Archaeotherium specimens are not too common. Imagine finding a complete skull, or even jaw of one of these beasts!

 

Genus: Archaeotherium

Location: Our Heritage Guest Ranch, Crawford, NE

DOD: 8/9/22

Length Of Specimen: About 3 Inches

The rarest in my collection is probably this pathological proboscidean vertebrae with vertebral fusion.  

 

Finding a mastodon or mammoth vertebra in relatively good condition would have been exciting enough for us, but one with a congenital deformity like this was truly one of a kind.

@MarcoSr. What an amazing find!  And very good of you to donate it considering its importance.

How does one even ID something like this?
