Jurassic
Gasosaurus
Gasosaurus constructus
The catalogue presents Gasosaurus as a carnivore member of Tetanurae that lived during the Jurassic, between 169.0–163.0 Ma. Its estimated range is 3.5–4.0 m in length and 150 kg in mass, giving a practical sense of scale. Reference material comes from Dashanpu Formation, Sichuan, China. Size and mass are approximations and may change with new fossils or methods.
