Locomotion Ecology in the Fossil Bird Ichthyornis

Explore the evolution of avian flight through a groundbreaking 3D shape analysis of the sternum in fossil and living birds. Delve into Talia Lowi-Merri's research from the University of Toronto, presented at the Royal Tyrrell Museum of Palaeontology. Discover how comparing fossil specimens with living relatives illuminates the development of ecological traits, particularly powered flight abilities. Gain insights into the critical role of the sternum in anchoring flight muscles and its significance in reconstructing avian flight origins. This 58-minute lecture provides a fundamental framework for understanding the locomotion ecology of the fossil bird Ichthyornis and its implications for broader avian evolution.
