Is This A Fossil

found this in the same area as the previous fosil. this looks like a knee cap, or plate bone of some kind. it has tiny pores or pits like a bone has. its about 10" - 11" across, and 2-3 inches thick in the center but tapers to a 1/4" thickness on the outer edge.

is this a fossil?

You're right, the texture is "bone-like", but only superficially so.

This may be something like a stromatoporoid.

That almost looks almost like a calcite formation .... or a weathered coral. Pretty cool.

The arrangement of the pores is way too regular for it to be purely mineralogical. It must have an underlying organic origin, whatever may have happened to it subsequently. There are some corals that grow in concentric forms like that but stromatoporoid (as suggested by Auspex) would surely be the front-runner?

The spacing of the holes reminds me of the corallites of Heliolites.

Just what I was thinking! - and there seem to be short septa showing in a lot of the holes.

which could be a crown or heliolitid cora, as suggested from members.

looks like a coral to me also.
