Another Jenkinsonia Varga

some proper bivalves

(unfortunately I'm not up to speed on bivalve taxonomy)

A decent Gastropoda (same case as the bivalves)

 

Edit: the trilobite pygidium is more likely

Kanoshia kanoshensis rather than Jenkinsonia varga as @piranha has pointed out.

Stop 3: the Permian

By the time the Gerster Fm. was layed to rest for the next 252 million years the trilobites had gone extinct all that remains at this locality is brachipods, bryozoans, and bivalves. The trilobites had gone extinct here.

Most of what we found was Timaniella pseudocamerata but there were a lot of bryozoan colonies and brachipods as well.

This pygidium is not a middle Cambrian ptychopariid: Jenkinsonia varga

Instead, it's a lower Ordovician pliomerid similar to: Kanoshia kanoshensis
