Bulgosuchus

Bulgosuchus is an extinct genus of prehistoric amphibians, known from an incomplete mandible and a femur recovered from the Bulgo Sandstone at Long Reef in Sydney, Australia. The type species is Bulgosuchus gargantua, which was named in 1999.
The type specimen is AM F80190, the posterior glenoid section of a left mandibular ramus, and the mandible is estimated to have been at least one metre long.
At the time of discovery, Bulgosuchus was described as the largest known temnospondyl from the Early Triassic.
