Macroevolution is the theme of my lab. Two main axes of research traverse this interdisciplinary field of science in the lab. Large scale patterns of evolution are be identified by looking at the evolution of details of skeletal anatomy and bone microstructure of vertebrate animals across time and ecosystem communities of plants and animals across time and geographic position. Most of the animal evolution work focuses on archosaurian reptiles (crocodiles, dinosaurs, birds, and relatives) during the Mesozoic Era (250 to 65 million years ago) although we also include fishes, amphibians, and relatively modern mammals for side projects. The evolution of ecosystem communities is limited to terrestrial plants and animals within the Mesozoic Era where we are attempting to describe how plants and animal communities are evolving at an ecosystem level using the current techniques of diversity and spatial ecology. Our contribution to the datasets is primarily through fieldwork in the Canadian High Arctic.
