Leptorhynchos (meaning "slender beak") is an extinct genus of caenagnathid dinosaurs known from the Late Cretaceous (Campanian-Maastrichtian aged) Aguja Formations of west Texas United States.[1][2] It lived about 80.5–72 million years ago. It is distinguished from its relatives Chirostenotes and Anzu by its smaller size, and by a more strongly upturned mandible, similar to that of oviraptorids. The specializations of the beak in Leptorhynchos and other caenagnathids suggest that they were herbivores. The species L. elegans has since been transferred to the genus Citipes,[3] leaving only the type species L. gaddisi in the genus.
