The catalogue presents Hadrosaurus as a herbivore member of Hadrosauridae that lived during the Cretaceous, between 80.0–75.0 Ma. Its estimated range is 7.0–8.0 m in length and 2.0–4.0 t in mass, giving a practical sense of scale. Reference material comes from Woodbury Formation, New Jersey, USA. Size and mass are approximations and may change with new fossils or methods.
