Therizinosaurus

Therizinosaurus cheloniformis

Therizinosaurus had the longest claws of any known animal, reaching up to 1 meter long. Despite being a theropod (typically carnivorous), it was herbivorous. It was one of the most bizarre-looking dinosaurs ever discovered.

Diet & Feeding

Herbivore

Therizinosaurus 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

Therizinosaurus 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.
