hibou wu Posted May 1, 2022 Share Posted May 1, 2022 Hi, this rock was found in a construction site in Bexar county, Texas. I think there are mostly mollusk shells, but I’m also really curious about the little tube things, which I’m guessing might be crinoids? Thank you for your help!

Al Dente Posted May 1, 2022 Share Posted May 1, 2022 The first photo shows several gastropods. This one looks like the cross section through a coral. 1 Link to comment Share on other sites More sharing options...

TyrannosaurusRex Posted May 2, 2022 Share Posted May 2, 2022 Gastropod cross sections. I’ve seen many turritella and tylostoma from Bexar and the surrounding counties. I have a piece almost exactly like this from near there. Tall thin one is definitely Turritella. Nice piece Link to comment Share on other sites More sharing options...

The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

Also a high percentage possibility. The better the provenance, the higher confidence we can wager assessments of formation. I was going off erosional pattern of the gastros in hard limestone, and haven’t found corals personally in the Buda. 1 Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils."
