The story in short
The genus Trierarchuncus dates to 2020, the year D. W. Fowler and colleagues described it. The name means “captain hook,.”
Fossils referred to Trierarchuncus date to the Late Cretaceous (Maastrichtian), roughly 72.2 to 66 million years ago. Finds come from the United States, including the Hell Creek Formation. It was a carnivore and walked on two legs.
The fossils of Trierarchuncus 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 Parvicursorinae, among the theropod dinosaurs.
