Dr. Alexandre Demers-Potvin has dedicated most of his palaeontological research to understanding Late Cretaceous North American non-marine ecosystems and their denizens across a wide taxonomic span, from new fossil insect species in Subarctic Canada to new dinosaur finds in Alberta and Saskatchewan. He has also pursued parallel projects on plesiosaur biology and joined expeditions further afield, from the Andean foothills of Colombia to the Sahara Desert of Niger. The present paper is a key component of his PhD thesis on the palaeoecology of Dinosaur Provincial Park.

Prof. Hans Larsson's main research questions revolve around vertebrate macroevolution using evidence from palaeontology, comparative anatomy, and developmental evolution. These have led him to contribute to our understanding of the evolution of powered flight from dinosaurs to birds, the fin-to-limb transition in fish, and the impacts of nanoparticles on embryonic development, as well as describing new dinosaur and crocodylomorph species from northern Africa. For the past 20 years, he has directed fieldwork across the badlands of western Canada as part of a long-term project on the region's palaeoecology during the Late Cretaceous Period.
