† Segnosaurus is a Late Cretaceous therizinosaur from Mongolia, with fragmentary material also reported from Japan. It was a large, slow-moving herbivore with elongated claws, a pot-bellied body plan, and reduced teeth suited to plant material.

Diet & Feeding

Herbivore

Segnosaurus 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

Segnosaurus 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.
