Recker Posted February 26, 2019 Share Posted February 26, 2019 Came across this fossil today while out enjoying the sun. I've found coral before but the little cavities are usually infilled, this is like swiss cheese, wondering what it is. It feels like a pumice stone in weight and texture. Thanks in advance!

Recker Posted February 26, 2019 Author Share Posted February 26, 2019 Thanks so much, I appreciate your help. What accounts for the type of matrix that it's in? Along with this one I found two others that are hash plates, full of odds and ends yet same consistency, like a pumice stone not dense and heavy like most that I find?

Herb Posted February 27, 2019 Share Posted February 27, 2019 looks like limestone to me.

I think it's just that the pore spaces (cavities) in the rock have either been dissolved away, or were never completely filled. Fossils are sometimes preserved in volcanic ash but paleozoic deposits would not have the texture of pumice. It's not a geologically stable form of material. 1 Link to comment Share on other sites More sharing options...
