What caused the forming of this rock??

This rock has so many different formations, like it's been glued together. Can someone tell me how this can be melted in several places with such odd formation?

Looks like a piece of weathered limestone or dolomite, with a bunch of bits of shell or pebbles that have more resistance to weathering and make a rough surface.

Carbonite rocks are very susceptible to chemical weathering and can take very weird shapes. This is what creates most natural caverns.

I think, ynot is spot on!

Your rock looks very, very similar to the weathered, fossiliferous limestone clast in my rudist hunting area (St. Bartholomä formation, Styria, Austria).

Seems pretty cumbersome for an ashtray and hardly worth the effort!  And it must be a real pain to clean out.

I think a shot glass would be a better choice for an ashtray.
