Cambrian explosion

Utaurora celebratign Trans Pride! Utaurora is a relative of the Cambrian weirdo Opabinia. It's back was covered with filamentous gills that gave it a fuzzy appearance.

This design is of a wonderfully odd creature that was alive during the Cambrian period. The creature actually existed all those years ago. The fossil remains of the Tully monster can be found throughout Pennsylvania and Illinois.

A couple Cambrian critters festively decked out for the holidays!

Anomalocaris! Cute design fitting for people who loves prehistoric animals. It can be given as a Birthday gift or Christmas gift! Design is also fitting in time for Dinosaur Day (June 1) and National Fossil Day (October 13)!
