JamieLynn Posted June 23, 2021 Share Posted June 23, 2021 Howdy! Found this little piece in an area where I have found quite a bit of coral. It is a bit different than previous coral finds, but does have similarities. It is just a "finer" grain of striations and pores and not quite as regular as other coral finds. So it is making me question whether it really is coral or perhaps rudist or just geologic. It is in an area of Georgetown and Buda Formation Undivided with some Glen Rose Formation upstream in Hays County. It is 1 1/4 inch. Thanks for any help!

Rockwood Posted June 27, 2021 Share Posted June 27, 2021 They just don't make corals like they used to back in the old days (Paleozoic) anymore. If I remember right Hans is no looser when it comes to these things. 1 1 Link to comment Share on other sites More sharing options...
HansTheLoser Posted June 27, 2021 Share Posted June 27, 2021 Interestingly, this coral looks very much like a Paleozoic one because it has a marginarium and lonsdaleoid septa. But the genus is not related to Amphiastreids that look much alike a Rugosa, it belongs to the family Aulastraeoporidae. Preverastraea reaches from the Upper Barremian to the Cenomanian and I have seen other material from Texas. 3 Link to comment Share on other sites More sharing options...

I'll get it under the microscope camera and see if I can get a close picture. www.fossil-quest.com Link to comment Share on other sites More sharing options...
