Apr 22, 2009 · Natalia Rybczynski unearthed the new animal at Devon Island, Canada and worked out that it must have swam through the waters of the Arctic circle around 20-24 million years ago. She named it...
The discovery of Puijila is important as it represents a morphological link in early seal evolution, and one that appears to morphologically precede the more familiarly structured genus Enaliarctos, despite apparently being a younger genus.
Apr 22, 2009 · Seals evolved from carnivorous ancestors that walked on land with sturdy legs; only later did these evolve into the flippers that the family is known for. Now, a beautifully new fossil called Puijila illustrates just what such early steps in seal evolution looked like.
Apr 22, 2009 · The newfound species, dubbed Puijila darwini, might be the long-sought missing link in the evolution of pinnipeds — a group that includes modern seals, sea lions and walruses — explaining how the...
Apr 23, 2009 · The earliest well-represented pinniped, Enaliarctos —a marine form with flippers—has been found on northern Pacific shores of North America. It had been theorized for some time that pinniped...
Apr 23, 2009 · Scientists in Canada's Arctic have discovered the fossil of a previously unknown web-footed carnivore that helps explain how seals developed from land-based mammals.
