Jurassic
Cetiosaurus
Cetiosaurus oxoniensis
The catalogue presents Cetiosaurus as a herbivore member of Cetiosauridae that lived during the Jurassic, between 175.0–168.0 Ma. Its estimated range is 15.0–18.0 m in length and 11.0–27.0 t in mass, giving a practical sense of scale. Reference material comes from Chipping Norton Limestone, Oxfordshire, England. Size and mass are approximations and may change with new fossils or methods.
