Therizinosauria

North America's first definitively recognized therizinosaur, a broad-bodied theropod with leaf-shaped teeth, four-toed feet and enormous curved hand claws.

A giant, plant-eating theropod from Mongolia known chiefly from enormous forelimbs and blade-like claw bones; its familiar long-necked, broad-bellied body is reconstructed from more complete relatives.

A medium-sized Mongolian therizinosaur with only two functional fingers and a rare three-dimensionally preserved keratin claw sheath.
