Fossil that looks like a finger, found in Puerto Rican beach site

Recommended Posts

So the beach was recently excavated and what was covered by the ocean for so many years, dried out and the sand was excavated and made into huge dunes full of old seashells and mysterious oysters and conches. I found many bivalves and i stumbled upon this weird stone that is covered in fossil like formations and shells. Any idea what it could be? Is it a fossil? Is it extinct? Its driving me NUTS.

I think it could be a serpulid.

Not a clue what this is, but very interesting.   It does look very 'worm' like.

It looks like a teredinid, maybe Kuphus.

 

" Fossils of the extinct species, Kuphus incrassatus, have been found in rocks in Jamaica, Mexico, Panama, Puerto Rico, Trinidad and Tobago, Florida and Mississippi. " -

according to Wikipedia

So how old is it?

If the ID is correct, probably Miocene or Oligocene, anywhere from roughly 5-33 million years old. (My somewhat educated guess. Others might have better info.)

A very close friend of mine is from that very area. His father is an archaeologist there. Small world!

I climb the boulders on the beach when we visit there and my wife has family in Aguada as well as Coamo. We will be out there again in September, I can’t wait.
