Picked this up on the California coast between Jamala Beach and Jade Cove last summer. I put it through all four cycles and it came out dull. I have no clue what it is. I need a bit of help. Thanks! Attachments:

Looks like a fossil. Possibly horn coral.

Boy I would've guessed horn coral too except there ain't no horn coral aged rocks in that area at all. I've hunted that area a bit and the rocks on those beaches aren't that old, mostly Jurassic to more recent stuff. Looks to definitely be a fossil of some sort, perhaps a Pinna sp. bivalve but you've got me stumped.....Mel

Don't think it's a bivalve Mel. Check the way the lines radiate out from the center in the first pic. Almost has to be some sort of coral.

could be an ancient fossil when that part of the continent was attached somewhere else

There are a lot of sedimentary rocks around there. Some have layers that people confuse with petrified wood. Mel is right about the area being too young. You can cut the end off and see if there are corral markings but I'm betting you will see only layers.

Jake: it depends on which part of the fossil you are looking at. . If it's just the end section of a Pinna sp. they appear very much like coral. We have cretaceous examples here in Texas and when you first pick up the tip sections of the shells, you'd think you were looking at horn coral until you realize they horn corals were wiped out in one of the great extinctions and their fossil do not exist in Cretaceous limestone beds. West coast of the US is even younger and I've not seen horn corals there. Closest spot I know of for rocks that age is in southern Nevada.....Mel

Fossil for sure!Kind of looks like a broken piece of "HOMOTELUS",really can't tell from the pics...Its as close as I can come to a guess....... Has the same line fractures as the pic's I have seen on the species....

Cool... and here I was thinking "HOMOTELUS" was the recently revised military policy....
