Spool Rock

I found this on the beach in Cayucos CA buried in the sand and mud.


The beach was thrashed by the previous week's storms and I found this rock. It's smooth and looks like a spool.

I know you identify sea glass but if you can give me any information, or a site where I can send this in for identification, I would appreciate it.

Fish Vertebra Fossil?
by: David

Rather than fossilized shark cartilage, this would more likely be a fish vertebra fossil.

We find vertebrae here on the beach in Peru that is similar. Run a Google search on fish vertebra fossil.

However, the piece in your photo appears to be too smooth on the sides and ends to be a vertebra, but... who knows?

possible fossil
by: Steve

We cannot tell the size of this by the picture but by describing to a friend, this may be fossilized shark cartilage.

Like the teeth that are commonly found.

I KNOW WHAT THIS IS
by: Judy H

I found out that this is an Amazonite ear plug.
