collector Posted December 22, 2015 Share Posted December 22, 2015 Here are a couple that I have. There is a busy coral with crystals inside. A picture taken through a microscope is of a crinoid stem or arm with crystals. The picture of the fossil isn't as nice as it looked just peering through the microscope. The last one I am not sure there are fossils on but I do like the yellow crystals. Patti Link to comment Share on other sites More sharing options...

BobWill Posted December 30, 2015 Share Posted December 30, 2015 This internal mold of a cretaceous clam is entirely covered with what I guess is calcite. It's very translucent and varies from 2 to 5 mm thick with a gap in some places between the crystals and the limestone beneath. Link to comment Share on other sites More sharing options...
