Tiktaalik

Tiktaalik has a possibility of being a representative of the evolutionary transition from fish to amphibians. It is an example from several lines of ancient sarcopterygian fish developing adaptations to the oxygen-poor shallow-water habitats of its time, environmental conditions which are thought to have led to the evolution of tetrapods.[2]
It and similar animals may possibly be the common ancestors of the broad swath of all vertebrate terrestrial fauna: amphibians, reptiles, birds, and mammals.[3] The first well-preserved Tiktaalik fossils were found in 2004 on Ellesmere Island in Nunavut, Canada.
