The story in short
The genus Ptychotherates dates to 2026, the year S. Srivastava and S. J. Nesbitt described it.
It lived in the Late Triassic (Norian · Rhaetian), roughly 227.3 to 201.4 million years ago. Finds come from the United States, including the Chinle Formation. It was a carnivore and walked on two legs.
The fossils of Ptychotherates are too incomplete for a responsible length, hip height, or weight, so those fields are left blank on purpose.
On the family tree it sits in Herrerasauria, among the earliest dinosaurs.
