What is this rock from Nor Cal beach?

[huhrik]

Would love your help with these few I found on a Nor Cal beach? Those are already etched with acid and wet.

Looks like a egg fossil. We would find lots of fossils along the cliffs when I was a kid in Point Arena, Way up north.

> Thank you! Is it really a fossil or just a name for a composite rock? Yes, yes, near point Arena indeed! Stayed in Gualaga and explored the beach.

This is why I think its a egg, but I'm not a expert by no means. I would get a paleontologists to look at it.
