Speaker Series 2018: Late Ice Age Mammals on Vancouver Island

As the last retreated 14,000 years ago, three giant mammal species—bison, ground sloth and short-faced bear—colonized Vancouver Island and the San Juan Islands. Megafauna (large or giant animals) fossils from the islands are rare due to acidic soils, but survive in pond deposits buffered by lime from underlying marine shells. Megafauna thrived south of the … Continue reading Speaker Series 2018: Late Ice Age Mammals on Vancouver Island

Speaker Series 2017: Extinction of Mainland and Island Mammoth Populations in Alaska 6,000 Years Ago

The extinction of mammoths is the most prominent of Late Pleistocene extinctions that wiped out nearly 70% of large mammals (megafauna) from western Europe through South America about 10,000 years ago. However, on small islands off the coast of Alaska and Siberia, populations of mammoths persisted for many thousands of years after mainland populations disappeared. … Continue reading Speaker Series 2017: Extinction of Mainland and Island Mammoth Populations in Alaska 6,000 Years Ago

Speaker Series 2016: Fossils of the Night – The History of Bats Through Time

Bats represent one in every five species of mammals in the world — there are at least 1,300 living species of bats. Not only are bats diverse, but they can be remarkably abundant with some species living in colonies that number in the millions of individuals. Bats are also geographically widespread. They are known from … Continue reading Speaker Series 2016: Fossils of the Night – The History of Bats Through Time
