Is this a fossil? Strange rock found on SF beach
Hello again! I found this rock a while back and have been mystified by it. It looks sort of like a fossil to me, but I don't know what of. Friends have suggested a stromatolite but that doesn't seem quite right.
I found this on a beach in San Francisco, California. Whatever it is, it's been worn down by water.

Any ideas? Thanks in advance!
Boesse, nice ID! I would have never guessed barnacle.
These kinds of finds are great. Although a worn, broken fragment that many of us might not bring home, it sparked a fascinating volley of thoughts and ideas and resulted in learning something new.
Mooflyrock, thanks for posting it. This was pure "edutainment"
