The story in short
The genus Leptorhynchos dates to 2013, the year N. R. Longrich and colleagues described it.
Fossils referred to Leptorhynchos date to the Late Cretaceous (Campanian), roughly 83.6 to 72.2 million years ago. Finds come from the United States, including the Aguja Formation. It was an omnivore and walked on two legs.
The fossils of Leptorhynchos 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 Caenagnathidae, among the theropod dinosaurs.
