Seen below is the cast of a tooth from Dilophosaurus, one of the earliest large dinosaur predators. Unlike the Jurassic Park version, the real Dilophosaurus could not spit, and did not possess a neck frill. The real version was also much larger than the movie portrayal. A glance at the image above shows that an adult Dilophosaurus could easily look a grown human in the eye.
Dilophosaurus would have been one of the largest, if not the largest, predator in its environment. Tracks from the area where Dilophosaurus was found indicate the possibility of a larger predator from that time and place, but no bones or skeletons have been recovered from that animal as of yet. Dilophosaurus would have been capable of taking on prey ranging from the larger prosauropods to smaller prey such as fish. Given that the Triassic-Jurassic extinction had just taken place, Dilophosaurus could probably not afford to be terribly picky in terms of food.
One thing that the Jurassic Park franchise does appear to have gotten right is the aggressive and hardy nature of Dilophosaurus. The holotype specimen has numerous pathologies present, including evidence of infections, puncture wounds, fractures, and withering of a limb. Most of the pathologies are concentrated on the pectoral (arm and shoulder) girdle, and probably happened at the same time. A possibility is that the injuries were caused by a combination of a fight with another animal, combined with the Dilophosaurus being thrown on or against something hard, like a tree, rock, or the ground. The uninjured arm is noticeably thicker than the injured one, meaning it was the one being used after the injuries. This also indicates that the Dilophosaurus survived for months or even years after the event. The icing on the cake for this animal was that the third finger of the right hand was rendered unable to flex from this series of trauma, meaning that this Dilophosaurus was perpetually giving the world what we now call the ‘freeway salute.”
