Cretaceous
Lambeosaurus
Lambeosaurus lambei
The catalogue presents Lambeosaurus as a herbivore member of Hadrosauridae that lived during the Cretaceous, between 76.5–75.0 Ma. Its estimated range is 9.0–15.0 m in length and 5.0–7.0 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 Lambeosaurus, the PBDB records the taxonomic attribution as Parks (1923).
