Jurassic
Gargoyleosaurus
Gargoyleosaurus parkpinorum
The catalogue presents Gargoyleosaurus as a herbivore member of Ankylosauridae that lived during the Jurassic, between 155.0–150.0 Ma. Its estimated range is 3.0–4.0 m in length and 300–500 kg in mass, giving a practical sense of scale. Reference material comes from Morrison Formation, Wyoming, USA. Size and mass are approximations and may change with new fossils or methods.
