Darla is an associate professor of dinosaur paleobiology at the University of Calgary in Canada. Darla’s research is primarily in the area of dinosaur paleobiology, with particular interest in theropod dinosaurs as well as the evolutionary relationship between dinosaurs and birds. Darla was a primary researcher describing the first dinosaurs preserved with feathers from the Americas, found in a species of ostrich-mimic dinosaur from Alberta, Canada, and has published a number of scientific papers related to eggs, babies and nests of dinosaurs in order to help understand behavioral and other biological implications of these fossils.
