Students will learn about the various hypotheses regarding the End-Cretaceous extinction
I have gone on several digs since 2018 in Wyoming, the Dakotas and Montana under the supervision of Dr. Paul Sereno. Studied and got certified in Paleontology under Philip J. Currie at the University of Alberta. Mentored by Prof. Tom Holtz at the University of Maryland. Worked as an educator at the Smithsonian Museum of Natural History pre-pandemic.
There is no prerequisite as this class goes into the various scientific debates. While this will discuss aspects of chemistry and geology, there is no need to have a prior background knowledge in this topic.
This class involves looking at an extinction event. As such, when documentary clips are used to showcase the Chixiclub theory for example, dinosaurs will be shown dying.
