Introduction to the Trilobites – virtual lab

Michelle M. Casey and Bruce and  have written a very nice virtual lab using trilobites as a model system for teaching undergraduates (sophomores/juniors) about macroevolution. The lab has plenty of high quality images with detailed explanations, so it is appropriate for use at institutions that don’t have extensive fossil collections.

Check it out: Introduction to the Trilobites (updated on 8 July, 2014).

A key to the questions is available (on request).

You can also check out: their publication on using the lab, and the the middle school lab.
