Real vs. Fake Trilobite Fossils and How to Tell the Difference (Revised)

Useful information for determining whether trilobite fossils are originals or casts (with a little geology humor thrown in).

Like this video to help the Proetus trilobite pay for rehabilitation.

Special thanks to everybody that provided constructive criticism in my previous "Real vs Fake Trilobites..." video! Because of your feedback, I was able to make a much better version.
