East Rock, West Rock, and the Triassic-Jurassic Extinction: A Virtual (Webex) Program – Presented by Sophie Westacott Member of the Peabody Museum Speakers Bureau on Wednesday, February 3 at 7:00 p.m.

Sophie Westacott, Member of the Peabody Museum Speakers Bureau will speak about East Rock, West Rock, and the Triassic-Jurassic Extinction.

Some 200 million years ago, an extremely productive bout of volcanic eruptions spewed tons of carbon dioxide and methane into the atmosphere, along with a lot of lava. The lava cooled to form East Rock, West Rock, and many other rocks, together known as the Central Atlantic Magmatic Province. The greenhouse gases caused tremendous global warming, an example from Earth history that we can learn from today. This talk will explore this tale of ancient climate change and mass extinction, told in part through familiar places around New Haven.

This program is made possible by the Yale Peabody Museum of Natural History and the Peabody Museum Speakers Bureau.

This free presentation will be held virtually on Webex (very similar to Zoom). To register to attend, please contact Cynthia, Community Services Librarian, at cgwiazda@hagamanlibrary.org. You will then be sent a Webex invitation link to join the program.
