OTTAWA ? Canadian and American fossil hunters have found the remains of
strange new species in the high Arctic, a ?walking seal,? that had long
legs and webbed feet.

It's a transitional form that shows how seals, sea lions and walruses
went from land animals to sea creatures, the researchers report in the
latest edition of the British journal Nature.

An expedition led by Canadian Museum of Nature paleontologist Natalia
Rybczynski found the bones of an animal matching that description in the
Haughton crater on Devon Island in the summer of 2007.

The Haughton crater is about 20 kilometres in diameter and was created
when a meteorite crashed to Earth, perhaps as much as 39 million years
ago. It filled with water to become a lake. Today it is a polar desert
and researchers from the National Aeronautics and Space Administration
and the Canadian Space Agency have used it to test ways of living and
working on Mars.
