Cretaceous
Sauroposeidon
Sauroposeidon proteles
The catalogue presents Sauroposeidon as a herbivore member of Brachiosauridae that lived during the Cretaceous, between 112.0–110.0 Ma. Its estimated range is 27.0–34.0 m in length and 40.0–60.0 t in mass, giving a practical sense of scale. Reference material comes from Antlers Formation, Oklahoma, USA. Size and mass are approximations and may change with new fossils or methods.
Evidence-backed summary
For Sauroposeidon, the PBDB records the taxonomic attribution as Wedel et al. (2000).
