The massive, shuffling dinosaur seems an improbable cross between ground sloth and pigeon yet stands taller than an elephant. Its brown, bristle-like feathers are broken up by a shock of blue around its neck and head, and sword-like claws extend from its arms. Therizinosaurus are tall, herbivorous theropods native to dense forests. These thick-set creatures sport great bellies, muscular haunches, and thick?set necks that allow them to sit comfortably as they browse for food. Their massive claws are used to harvest great clumps of foliage, pulling it into their maws as they feed. The claws can also rip apart any predator who dares attack them. Feeding therizinosaurus have been compared to gluttonous halflings, happily shoving everything they can reach into their bottomless bellies.

Territorial Giants. Therizinosaurus are not truly solitary creatures, but they react poorly to anything they see as a threat.

Annoying humanoids, aggressive wolves, predatory dinosaurs, and even herbivores who share the therizinosaurus’s favored foods are chased away with deep, guttural bellows and flourishes of scythe-like claws.
