Oregon’s premier paleontology, Dr. Bill Orr will speak on the topic of "Extinctions." Although we perceive them as catastrophes, mass extinctions are one of the most powerful tools geologists employ as time markers. The presentation will address the major phanerozoic extinctions was well as their probable causes. Included will be a summary of the ever changing cause and effect of the Cretaceous/Tertiary event.
