Special Cranbrook Lecture: "Still the Crater of Doom"


Geologist, paleontologist, and Cranbrook Institute of Science Curator of Earth and Life Sciences John Zawiskie will critically review the historical development of the asteroid impact theory for the extinction of non-avian dinosaurs, including past controversies regarding the timing of the mass extinction and the impact that formed the massive Chicxulub crater in the Gulf of Mexico.

John’s presentation will be highlighted by his own field photography of the strata in the Raton Basin in Colorado and New Mexico.

Stay after this lecture until 10pm and enjoy a visit to the museum, including observatory access if it is clear, planetarium shows (at extra cost), and the special exhibit Dinosaurs: The Lost World. Museum entry is free courtesy of the MASCO Corporation Foundation’s Free First Fridays program.
