Scientific name: †Majungasaurus crenatissimus (Depéret, 1896) - Dinosaur family: Abelisauridae - tooth.
Location: Berivotra village near the northwestern coast of Madagascar
Geological Formation: Maevarano Formation, Madagascar's
Mahajanga Basin
Age: Late Cretaceous, Maastrichtian stage, ~72-66Ma
Size 2cm
DESCRIPTION:
Nice nicely preserved specimen. Not restored or glued. Well developed carina (serrations).
Majungasaurus was a medium-sized theropod dinosaur predator, living at the end of the Cretaceous period, was one of the last dinosaurs to roam the earth.
Maevarano Geological Formation
The geological group where this tooth was found, the Maevarano Formation, located in northwestern Madagascar's Mahajanga Basin, is a Late Cretaceous geological unit known for its fluvial and floodplain deposits of sandstones, siltstones, and claystones. Formed in a semi-arid, seasonal climate, it preserves a rich fossil record, including the theropod Majungasaurus, sauropod Rapetosaurus, crocodyliforms, and early birds. Its significance lies in revealing a diverse Gondwanan ecosystem just before the K-Pg extinction, with Majungasaurus fossils showing evidence of cannibalism.
