Susan E. Evans

Susan E. Evans is a British vertebrate paleontologist recognized for her research on fossil lizards, amphibians, and the early evolutionary history of lepidosaurs. She has published extensively on Mesozoic reptiles and the origins of modern squamate lineages.

Susan E. Evans is a professor in the Department of Cell and Developmental Biology at University College London (UCL). She has been associated with UCL's research groups in evolutionary morphology and paleontology for much of her academic career.

Lepidosaurs are a superorder of reptiles that includes all modern snakes, lizards, and the tuatara, making them one of the most diverse groups of living reptiles. Evans's research on early lepidosaur evolution has helped clarify how these animals diversified from their Mesozoic ancestors, filling important gaps in the reptile fossil record.

Susan E. Evans has described and named numerous extinct lizard and reptile species from fossil sites around the world, including specimens from the Middle Jurassic of England and the Cretaceous of Mongolia. Her work has been particularly important for understanding the transition from early diapsid reptiles to modern lizard groups.
