Can someone possibly clue me in on what this tiny bone is? It looks like it has a tooth attached or something of the likes...thanks in advanceBB968F77-83BE-42CC-AF81-D9EB603C5797.thumb.jpeg.7ddde4387b3eb09e19753dcf524e4a66.jpeg

For some reason this gives me a "rodent" feeling.  I don't know what that thing on it is.

 

World's smallest Mammoth jaw. Although the name "Mammoth" is definately  a misnomer in this case. :ighappy:

The thing on it is an actual piece of it. It reminded me of a tiny mammoth tooth as well when I found it.

Looks like a pharyngeal jaw from a fish with a tooth plate attached. These jaws are located in the throat of many fish. @Metopocetus may have an idea about that.

Some clearer pictures from multiple angles would definitely help.

Can you give us accurate measurements on the bone? Our European members have no idea of the size of a U.S. nickel. 

Please read some of the pinned topics on how to get your item identified.

It is roughly 1” x1” or 25mm length and width

Definitely a fish jaw. Not certain if an oral jaw or pharyngeal jaw element. The spongy bit is actually a tooth plate. The holes would hold small round teeth. 

 

A classic example from the Calvert region is at : https://www.dmme.virginia.gov/commercedocs/PUB_152.pdf

See page 97, specimens C1 & C2 for examples of this spongy surface. This figured specimens are not from the same animal or position, but clearly show the same type of dental surface.
