The San Bernardino Valley Amateur Astronomers will have a special guest lecturer, Dr. Mathew Wedel, Saturday, July 18, at their meeting at the San Bernardino County Museum. Wedel will talk about dinosaur extinction from a scientist's point of view.
The 7 p.m. meeting is free and open to the public.
Last spring Dr. Wedel spoke of his research on the History Channel's "Evolve" program and on Animal Planet's "Animal Armageddon."
Wedel earned a Ph.D. in paleontology from UC Berkeley and has worked on the origin of pneumatic bones and the respiratory systems of dinosaurs. In his research he compares the air-filled bones of today's birds to their distant dinosaur relations and uses this data to explain the evolution of the large size and long necks of dinosaurs.
He'll talk about his research on dinosaurs and birds in the field and in the lab, what the world of the dinosaurs was like in the Late Cretaceous period, the effects of the asteroid impact, and the potential for future asteroid impacts on earth.
