Beelzebufo (/biːˌɛlzɪˈbjuːfoʊ/ or /ˌbiːlzəˈbjuːfoʊ/) is an extinct genus of hyloid frog from the Late Cretaceous Berivotra and Maevarano Formations of Madagascar.

[1] But in later studies, animals of this species estimated to have grown to at least 23.2 cm (9.1 in) (snout-vent length), which is around the size a modern African bullfrog can reach.

[7] Beelzebufo most likely was a predator whose expansive mouth allowed it to eat relatively large prey, perhaps even juvenile dinosaurs.

[10] The fossils of Beelzebufo are from Madagascar, which, while still attached to India, separated from the coast of Somalia in the earliest stage of the Late Jurassic.

[1][5] The initial description of Beelzebufo hypothesis reignited interest and research into skeletal variation among living members of the Ceratophyridae.
