Cretaceous
Corythosaurus
Corythosaurus casuarius
The catalogue presents Corythosaurus as a herbivore member of Hadrosauridae that lived during the Cretaceous, between 77.0–75.0 Ma. Its estimated range is 8.0–9.0 m in length and 2.0–3.5 t in mass, giving a practical sense of scale. Reference material comes from Dinosaur Park Formation, Alberta, Canada. Size and mass are approximations and may change with new fossils or methods.
Evidence-backed summary
For Corythosaurus, the PBDB records the taxonomic attribution as Brown (1914).
