A creature that lived 375 million years ago and is thought to have been the first fish to have made the transition to land sported large pelvic bones in addition to its leg-like front fins, new research shows, suggesting that it was a more efficient walker than previously thought.
Tiktaalik roseae, discovered in 2004 on Ellesmere Island in Nunavit, Canada, is a key transitional fossil that links lobe-finned fishes and tetrapods, the first four-limbed vertebrates at the end of the Devonian period.

The move cost her her life, and its repercussions are still felt in Indian politics.
