“Weeks Formation”
In the Middle Cambrian the continent of Laurentia was equatorial and oriented about ninety degrees from its current position. Close to the shoreline limestone was deposited in shallow water reef environments and the fine offshore sediments yield remarkably well-preserved fossils like those found in the Weeks Formation. Trilobites of the genera Norwoodia, Gerospina, Meteoraspis and other arthropods such as Anomalocaris swimming on open water, medusae and Canadaspis populate this illustration.
