Titanosuchus ferox ("Fierce Titan crocodile") was a dinocephalian therapsid that lived in the Mid Permian epoch in South Africa.
Along with its close relatives, Jonkeria and Moschops, Titanosuchus inhabited present-day South Africa around 265 million years ago, in the Late Permian. Titanosuchus was a carnivore which measured over 2.5 m long and might have eaten both Jonkeria and Moschops, among other vertebrates. Its teeth included sharp incisors and fang-like canines, perfect for biting prey. Titanosuchus rivals that to Titanophoneus, which is also a carnivore and a dinocephalian, but it lived only in Russia. Titanosuchus should not be confused with the therapsid Eotitanosuchus, which belonged to a different family.
Parascapanodon and Scapanodon were thought to be distinct species, but later turned out to be the same species as Titanosuchus.
