Malerisaurus is an extinct genus of prolacertiform from the Late Triassic of India belonging to the family Protorosauridae.

Two incomplete Malerisaurus skeletons were discovered in what is thought to be the gastric contents of a Parasuchus hislopi. The fossils were retrieved from fluvial flood plain deposits of the late Triassic Maleri Formation of the Gondwana supergroup, India. Malerisaurus was a small eosuchian, presumably bipedal, and probably capable of climbing trees and swimming. The skull has some adaptations to a carnivorous diet, but is nevertheless unspecialised and probably more of an insectivore. Malerisaurus, seen as a diapsid skull, shows primitive and advanced facies in its unossified laterosphenoid, absence of antorbital and mandibular fenestrae, gracile form, primitive girdles, elongated cervicals and absence of dermal armour. The suborder Prolacertiformes currently represents four families: Petrolacosauridae, Protorosauridae, Prolacertidae and Tanystropheidae. Provisionally Malerisaurus is regarded as close to Protorosaurus. [1]
