Description: Therizinosaurus belongs to Therizinosauridae, secondarily herbivorous maniraptorans with pot-bellied torsos, small heads, and elongate necks. Fearsome claws likely harvested foliage, stripped bark, or served display instead of slashing predation. Feathers are phylogenetically assured, producing a surreal silhouette among Late Cretaceous Nemegt wetlands.

Features:
  - Unguals may exceed ~1 m along the outer curve
  - Gastralia and wide pelvis accommodate large fermentation guts
  - Integument included plumose feathers across the trunk

Related genera: Nothronychus, Erlikosaurus, Segnosaurus
