Exploring Geologic History

This podcast by Hammocks Middle School's Earth Science Department reviews how to use the New York State Earth Science Reference Tables. It focuses on linking index fossils from pages eight and nine with geological maps on pages two and three. The podcast provides examples of fossils from different periods, such as the Cambrian trilobite, Silurian crinoids and brachiopods, and Devonian coral, explaining how to identify their geological contexts using the reference tables.
