Gastonia
Gastonia burgei
The catalogue presents Gastonia as a herbivore member of Polacanthidae that lived during the Cretaceous, between 124.0–115.0 Ma. Its estimated range is 4.0–7.0 m in length and 1.9 t in mass, giving a practical sense of scale. Reference material comes from Cedar Mountain Formation, Utah, USA. Size and mass are approximations and may change with new fossils or methods.
