Cgs928 Posted March 22, 2018 Share Posted March 22, 2018 Hello all, I am still working on this very large project in the Lower Glen Rose Formation near Spring Branch, Texas. Are these marine fossils? Or are they minerals? Link to comment Share on other sites More sharing options...
ynot Posted March 22, 2018 Share Posted March 22, 2018 Mineral, the first picture shows some selenite, second looks like calcite. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough." My Fossil collection - My Mineral collection My favorite thread on TFF. Link to comment Share on other sites More sharing options...

mikeymig Posted March 22, 2018 Share Posted March 22, 2018 Looks more like gypsum. Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...
