Fossil Whales

9 Feb 2014

At ... research by a student at the University of Otago in New Zealand took him to California, to a geological formation in San Francisco Bay. He has managed to piece together, with some help, 21 mammals, including dwarf baleen whale, double tusked walrus, porpoises and dolphins, and a fossil whale, an early relative of the Minke. Published in the journal Geodiversitas (2014), the fossils are said to date back 2 million years ago, when the water off shore from California were warmer. Apparently this was due to the Bering Strait being a blocked passagewhich did not allow the movement of cold water down the western side of N America, as happens in the modern world.
