The name ‘dilophosaurus’ originated from the Greek ‘di’ (‘two), ‘lophos’ (‘crest’) and ‘sauros’ (‘lizard’); thus, a ‘two-crested lizard’.
It originated from the most characteristic feature – a pair of longitudinal, plate-shaped crests on its skull, which as if continued from the nose bone.
They are regarded too weak for any other function than visual display. A dilophosaurus was a carnivore, feeding off dead carcases, because its teeth were too weak to kill a large prey.
