Revision to rules for color in dinosaurs suggests connection between color and physiology

New research revising rules on deciphering color in dinosaurs may provide a tool for understanding the evolutionary emergence of flight and changes in dinosaur physiology. While surveying melanosome shape in fossil and extant specimens, a research team unexpectedly discovered that ancient maniraptoran dinosaurs, paravians, and living mammals and birds uniquely shared the evolutionary development of diverse melanosome shapes related to color. The similarity could relate to a key shift in dinosaurian physiology.
