Miami Beach Fossil ID

[amaanthawer]

 

Hello and Happy New Year from Miami! I found an interesting rock on the beach a little while back and I can't seem to determine what it is. Since it was found at Miami Beach, it should be Pleistocene Miami Limestone. The specimen is about 3 inches in length.

 

 

It looks quite similar to an image I found online of a seal humerus: 

 

 

Thank you :)

It's not bone,  looks something like sponge or coral but wait for expert to ID which I am not

Welcome to TFF, a friendly and educational place for all sorts of fossil enthusiasts. Your last photo is educational, bone under laying texture at the 4 corners and marine growths only on the outside.

 

I think your find is most likely well worn coral.
