‘Becoming a Fossil’ at Thacher Visitor Center at 2:00 p.m. Celebrate Earth Science Week at Thacher Visitor Center! Why do some creatures get preserved as fossils while others do not? What makes a good fossil anyway? Join us to learn about taphonomy, the science of fossilization, and the conditions that make a good impression in the fossil record.
