Qikiqtania wakei fossils

An article published in the journal “Nature” reports the identification of a precursor of the tetrapods that lived on today’s Ellesmere Island, in Canada, in the Devonian period, about 375 million years ago. A team of researchers named it Qikiqtania wakei and illustrated similarities and differences with Tiktaalik roseae, the possible ancestor of today’s tetrapods. The anatomical characteristics of Qikiqtania wakei indicate that it descended from the precursors of the tetrapods that ventured to the mainland but unlike Tiktaalik roseae it went back to the water, where it developed fins suitable for aquatic life.
