Sudan plated lizard (Gerrhosaurus major), also known as the great plated lizard or rough-scaled plated Lizard is a lizard of the Gerrhosauridae family.
The Sudan plated lizard is a fairly large lizard, adult size is 45–70 cm, whereof the tail is less than half the length. They are somewhat squat with moderately broad tails.
Being the most heavily plated of the Gerrhosaururidae, the species is easily recognised on the armour. The body and tail is covered in transverse bands of more or less square plate like scales, and head shields are fused to the skull. The armour makes the animals look a bit like the common perception of Mesozoic reptiles.
