June P Posted January 19, 2022 Share Posted January 19, 2022 I think I’ve posted before in the wrong area…hoping this is reaching y’all: found this in Bexar County San Antonio, Texas in my neighborhood which is new construction. In this area I’ve found a lot of petrified trees and other types of possible water creatures. I’ll attach those pics since I may have posted them in the wrong discussion area.. this looks like a shell of some sort and has beautiful little crystals in the ‘valleys’ of the sunburst pattern.. 1 Link to comment Share on other sites More sharing options...
Rockwood Posted January 19, 2022 Share Posted January 19, 2022 Shellfish is accurate I suppose, they are mollusks. They aren't like clams though, but free swimming cephalopods. It's a fragment of ammonite shell. Link to comment Share on other sites More sharing options...

Possibly the upper valve of a radiolitid, not the usual lower valve? I would like to see the cellular structure of a lower valve. Problem is, not all radiolitid lower valves have this cellular structure . Difficult! Franz Bernhard 1 Link to comment Share on other sites More sharing options...
abyssunder Posted January 19, 2022 Share Posted January 19, 2022 I agree. It is a rudist fragment (upper or lower valve). 2 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

June P Posted January 30, 2022 Author Share Posted January 30, 2022 Oh my gosh, Y’all! Thanks so much!!! Now I’m going to look these creatures up! I love this area of Bexar County Texas. Every time I walk in the old ranch area and dig through the soil, i find myself transported back in time-it’s so humbling and I find myself in a deep state of reverence!
