The Leptorhynchos is a genus of a type of herb as well as of a dinosaur. To denote a dinosaur of the Leptorhynchos genus, it is better to call it by the name of the type species to avoid confusion between the herb and the dinosaur. Apart from the herb, the Leptorhynchos is also used to denote a Late Cretaceous dinosaur genus of the Caenagnathidae family. The Leptorhynchos dinosaurs were discovered from the Aguja Formation of West Texas in the United States. The distribution of their fossilized specimens is also recorded from some parts of Canada and in the Dinosaur park formation of Alberta.

The species was named by four renowned paleontologists including Nicholas R.‭ ‬Longrich, ‬Scott Clark, ‬Ken Barnes, and Larry Millar. They also have another identity called Ornithomimus elegant. The most characteristic feature of this animal was its parrot-like thin beak and long thin claws. The Leptorhyncos is named after this characteristic identity of the animal. They predominantly occurred in the Upper Campanian Aguja Formation and only a single species called L. gaddisi has been assigned to this genus. To know more about the animal, keep on reading these facts.

Leptorhynchos Fun Facts

What did a Leptorhynchos look like?

The Leptorhynchos was a small-sized feathered dinosaur that belonged to the Caenagnathidae family of sharp billed and long neck dinosaurs. Different species of Caenagnathids have different body sizes and beak shapes. The shape of their beaks played a major role in their adapting and evolving processes in western North America. L. gaddisi are known from a very limited fossil collection but it is believed that they had features fairly similar to the other members of the group. It was considered to be a flightless animal with the snout turned into a parrot-like thin beak. The slender snout of the animal came to be known as the most characteristic feature of the species later. They also had elongated skinny claws and long necks. By studying their fossil structure, it was assumed that these Late Cretaceous flightless animals were similar to the present-day finches. The fossil of L. gaddisi was described as a primitive turkey-sized animal. They had a rounded chin and the bill was less upturned than its relative in Canada called L. elegans. Their mandibles were short but they were deep. The shape of the mandibles conveyed a lot about the diet of the dinosaur. The shape of the beaks of the type species distinguished them from the other species of Caenagnathidae.

How was the Leptorhynchos discovered?

The Leptorhynchos is a very newly discovered dinosaur species that supposedly lived around the Upper Campanian Aguja Formation of Texas. They were one of the members of the Caenagnathidae family of dinosaurs that were characterized by a bird-like beak and long necks. The fossils of the single species of Leptorhynchos dinosaur called L. gaddisi were distributed throughout a vast range in North America. Even though they are known from very scattered remains, it could be easily inferred from their remains that they were one of the North America Caenagnathids.  Nicholas R.‭ ‬Longrich took the main initiative to discover and describe the species. In 2013, by the joint venture of four paleontologists called Nicholas R.‭ ‬Longrich, ‬Larry Millar, ‬Ken Barnes, and Scott Clark the Caenagnathid was finally named.
