Dilophosauridae

Dilophosaurids were a widely distributed family of early carnivorous dinosaurs.
==Description==

Dilophosaurs were large graceful bipedal predators with lengths of 4 to 7 metres and estimated adult weights of 300 to 500 kg. They are well known for their distinctive head crests, which were probably used for mating displays, or to intimidate rivals.
Not only were they larger, they were also more evolved, acquiring characteristics absent in Triassic and early Jurassic coelophysoids. According to Tom Holtz, dilophosaurs share several derived features (synapomorphies) with averostrans, including a lacrimal fenestra (airsac opening into the upper corner of the lacrimal), reduced total number of maxillary teeth, and modified jaw joint.
