The simplest lifeforms on Earth today are bacteria, and it is likely that Earth’s first living organisms were similar. But how do we recognize something as small and simple as a bacterium in the fossil record? This talk by State Paleontologist Dr. Lisa Amati will present evidence about when and where the first life evolved on Earth and how we identify it. In addition, we will explore the profound impact lifeforms have had on our planet over time.

This program includes a 20-minute talk followed by brief Q&A. Participants are welcomed to bring their lunches.

Stromatolites

Stromatolites, or layered stones, are formed in very shallow marine waters by cyanobacteria mats (often called 'blue-green algae').
