Fossil Preparation Videos of Crinoids and Trilobites

Here are two YouTube videos showing trilobite preparation lab back in 2005. That is an amazing plate they quarried so many crinoids and the other plate showing so many intact trilobites and a starfish. The location is Erfoud, Morocco. The trilobites shown in the video are Selenopeltis bucci, Asaphus, Onnia and Bornstrella.

The second shows more of the lab. They have quite a fossil inventory there!

This picture shows what appears to be a Flexicalymene granulosa trilobite fossil. It was found in the Kope Formation (Eden Group) of Carroll County, Kentucky, USA. It dates to the Ordovician Period. This trilobite differs from the Flexicalymene meeki in that has a smooth surface on the cephalon while the F. granulosa has a gritty surface texture.
