SciCafe: End of the Megafauna with Ross MacPhee

Woolly mammoths and giant ground sloths are just a few of the strange animals that once roamed Earth, living on every habitable continent. But about 50,000 years ago, these “megafauna” began to disappear. What factors contributed to their disappearance? Why did some species survive while others did not? Ross MacPhee, curator in the Museum’s Department of Mammalogy, takes us on a journey back in time to the world of now-extinct megafauna, and explains what scientists think may have happened. A video version of this SciCafe will be available on the Museum’s YouTube channel on Saturday, December 22. This SciCafe took place at the Museum on December 5, 2018.
