Prepped Calymene breviceps Molts

Probably the most commonly found trilobite in the Waldron Shale of Indiana, the Calymene breviceps. These two fossils appear to be molts which were shed during the Middle Silurian Period (about 425-420 million years ago). See some more outstanding prepared trilobites like this one at the Weeks Trilobite web site.

Thanks to Mark for letting me photograph these.

Taxocrinus whitfieldi Crinoid

A prepped crinoid calyx fossil called Taxocrinus whitfieldi. I think this fossil is from Indiana and probably from the Mississippian Period. It just had a name label with it. Apologies for the image color has I had the camera set to the wrong lighting, the fossil it not that blue in tint. Thanks to Mark for letting me photograph it. Units on scale are in inches.

Moroccan Cone Fossil

 These fossils were recently brought back from the Tucson Fossil Show. They are some sort of cone fossil that no one seems to know the name of. The time period others seem to be settling on is it is from the Eocene. Fossils were found in western Sahara, Morocco.

Thanks to Mark for letting me photograph them. Scale in picture is in inches.
