The Caenagnathus it is a genus of dinosaur late Cretaceous caenagnathid oviraptorosaur, which is known through partial remains that include the lower jaws, a tail vertebra, and limb bones.

All of them were found in the Alberta Dinosaur Park Formation, Canada, and its history is confusing. When jaw bones were found in 1936, they were initially thought to be the remains of a bird.

However, in 1988, a remnant found in 1923 was discovered in a warehouse, which served to link several fragmentary species of other oviraptorosaurs into a single dinosaur, which was classified in the Genus Chirostenotes and the name given to 1936 was kept: Caenagnathus.

After studying History at the University and after many previous tests, Red Historia was born, a project that emerged as a means of dissemination where you can find the most important news of archeology, history and humanities, as well as articles of interest, curiosities and much more. In short, a meeting point for everyone where they can share information and continue learning.
