(2022).[31]
  • A large dinosaur tracksite preserving theropod tracks and abundant hadrosaurid tracks is described from the Upper Cretaceous (Campanian) Wapiti Formation (Alberta, Canada) by Enriquez et al. (2022), who evaluate the implications of this finding for the knowledge of the paleoecology of dinosaurs known from the Wapiti Formation.[32]
