Tropeognathus (meaning "keel-tipped jaw") is a genus of large pterosaurs from the late Cretaceous Period of South America. It was member of the Ornithocheiridae (alternately Anhangueridae), a group of pterosaurs known for their keel-tipped snouts, and was closely related to species of the genus Anhanguera. It is known primarily for the species Tropeognathus mesembrinus, though a second species, Tropeognathus robustus, has been named in the genus. The keel-tipped mouth had a similar appearance to that of the Coloborhynchus.

Discovery and naming[]



In popular culture[]

  • "Ornithocheirus" is seen in the Walking with Dinosaurs episode "King of the Skies", in which an old male is featured as the main character. It also makes another appearance in Walking with Dinosaurs in the special "Land of Giants". Both Ornithocheirus are based on Ornithocheirus mesembrinus, which are now belived to be Tropeognathus mesembrinus, not Ornithocheirus. Tropeognathus had a wingspan of only 7-8.2 meters (23–27 feet) max, not 12 meters (40 feet). Even Ornithocheirus is only 5 meters (16.5 feet). There is no evidence that Tropeognathus or Ornithocheirus traveled the globe. Giant pterosaurs are now known to not have been consummate gliders.
  • Tropeognathus can be created in Jurassic World: The Game as a common pterosaur. Its appearance on its base form is similar to the Tropeognathus in Walking with Dinosaurs.
  • The Tropeognathus is also an upcoming dino in the game [1]Ark survival evolved
