Bill Krebs, UCLA & WMRC alumni will be presenting on the Cambrian fossil history of the White Mountains.

The Cambrian Explosion was a seminal event in the history of life on Earth.

It occurred ~ 541 mya at the beginning of the Cambrian Period and is characterized by the first appearance of abundant mineralized invertebrates, burrows, a negative δC13 excursion, the extinction of most Precambrian metazoans, and disappearance of widespread microbial mats and stromatolites.  Phyla of all modern marine invertebrates appeared during the Cambrian Explosion and well as the ecological relationships that now exist between them.   Evidence for this event in the White Mtns. consists of stromatolites, sedimentary textures indicative of microbial mats, fossils of mineralized marine invertebrates, and trace fossils (e.g., burrows).  In Bishop, it’s a short drive to the distant past and strange old world. 

This event is free & open to the public. It will be recorded and posted to our YouTube channel at a later date.
