Megaloolithus siruguei

† Nyasasaurus parringtoni may be the oldest known dinosaur or dinosauriform, from the Middle Triassic (~240 Ma) of Tanzania. If it is a true dinosaur, it pushes back the origin of the group by ~10-15 million years, potentially changing our understanding of dinosaur origins.

Diet & Feeding

Herbivore

Megaloolithus siruguei was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Cretaceous Late Mesozoic Era

Megaloolithus siruguei lived during the Cretaceous Late period of the Mesozoic Era, approximately 100.5 to 66.0 million years ago.

The final age of dinosaurs, featuring iconic species like Tyrannosaurus rex, Triceratops, and Velociraptor. Dinosaurs reached their peak diversity before the catastrophic asteroid impact at the Chicxulub crater ended the Mesozoic Era.
