Official Dilophosaurus model by Callie C.
With their competition wiped out by the Triassic extinction, the door was open for the dinosaurs to be the new top dogs, and Dilophosaurus is the epitome of this, being one of the first theropod apex predators. Already surpassing any apex predator alive today, it was the largest animal in the entire region, even larger then any of the animals it preyed upon. Equipped with strong jaws able to puncture bone, powerful and flexible arms, and stout legs, it was a very efficient, fast, and agile hunter.
It is also noteworthy for the iconic crest present on the top of its head, which were too brittle for combat, likely being used for sexual selection (a tool for males to attract females with, a large colorful crest being a sign of strength and good health) and species recognition.
Dilophosaurus will be the main focus of Dinosauria's second episode, primarily a family of them. The episode will explore several aspects of their lifestyle, especially their growth from hatchling to adulthood.
