First Described: 1901

Genyodectes was an early Cretaceous ceratosaurian from the Aptian age, around 112 million years ago. It was found in the Cañadón Grande, Departamento Paso de Indios in the Chubut Province of Argentina. It's not known from many remains - mainly just the front of the jaw and upper mandible and many teeth. However, given the arrangement of the teeth, it seems to resemble Ceratosaurus more than other theropods. Given that, it was only recently that it was classified as such, and has been named everything from a megalosaurid to a tyrannosaurid. However, recent removal from its display matrix has allowed it to be classified as a ceratosaur. It was also one of the earliest dinosaurs found in South America.
