Fossil proves hyenas once roamed Canada's Arctic Plains
    18 June 2019

A 50-year-old mystery surrounding a pair of fossilised teeth has been put to rest by new research that suggests hyenas once roamed Canada's Arctic.

A team of researchers have identified the teeth, which were found in the Yukon in the 1970s, as belonging to hyenas one million years ago.

Their findings were published on Tuesday in scientific journal Open Quaternary.

The discovery sheds new light on the evolution of the ferocious scavengers.

The two teeth were found during a paleontological expedition in Yukon's Old Crow Basin in 1973.

It is was not always cold.  For example:

... Alaska and the polar regions were once hot enough to support flora and fauna as tropical as palm trees and crocodiles. A new study on the Eocene epoch, which lasted from around 56 million to 34 million years ago, concludes that although the time period was known to be among the hottest in Earth's history...
