MarieIsACommonMiddleName Posted April 24, 2022 Share Posted April 24, 2022 (edited) Hello, the decorative rocks in the complex where I live in Louisiana have fossil traces. Many (possibly all) seem to be metamorphic from originating sedimentary layers. Mostly shells and coral imprints, but I've found two like this now. What is this please? Is it vertebrate or invertebrate? I don't know the actual origin of this rock, where the company that provided it gets them from. It is about one quarter inch in size.

Al Dente Posted April 24, 2022 Share Posted April 24, 2022 It is a crinoid stem fragment. The crinoid stem has dissolved, leaving just the impression. 4 Link to comment Share on other sites More sharing options...

Mark Kmiecik Posted April 24, 2022 Share Posted April 24, 2022 3 hours ago, MarieIsACommonMiddleName said: Thank you both. Crinoids are very common fossils, literally everywhere. If you look around in that material you should be able to find many more and possibly better ones where the stem itself is still present. Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
