Infernogallus

Funston et al., 2026

Infernogallus is an extinct genus of oviraptorosaurian theropod dinosaur in the family Caenagnathidae, known from multiple localities in the Late Cretaceous Hell Creek Formation of the United States. The genus contains a single species, Infernogallus jamesi, known from a partial articulated skull and skeleton and several isolated cranial remains. With an estimated body mass of around 12 kg (26 lb), it is a small caenagnathid. The skull of the holotype specimen is the first nearly complete and articulated skull discovered for a caenagnathid. It shows a reorganization of jaw muscles that may be an adaptation for fruit eating, similar to some modern parrots but unique among non-avian theropods.
