Found this on a gravel bar just below boundary to Permian but not sure about source.

I had some trouble getting focused photo of edges. I'm thinking possibly algae.

Drusy quartz, I think, or could be drusy calcite. 

See if it fizzes with weak acid.

is there such thing as a carpet sponge?....but seriously to me it looks corral like and it is on a layered foundation of fossil material....but then I am a newbie and its a guess based on my observation...eagerly waiting for the experts opinions....

I think it is a mineral deposit,  wonder if this could be a bryozoan?

Can You post a close up picture of the surface (show in first picture).

Yes, it fizzes.

That means is not quartz, but calcite.
