Majungasaurus crenatissimus
The catalogue presents Majungasaurus as a carnivore member of Abelisauridae that lived during the Cretaceous, between 70.0–66.0 Ma. Its estimated range is 6.0–7.0 m in length and 1.1 t in mass, giving a practical sense of scale. Reference material comes from Maevarano Formation, Mahajanga, Madagascar. Size and mass are approximations and may change with new fossils or methods.
