Remember the frilled-neck dinosaur that spits poison in the 1993 'Jurassic Park' movie?
Well, every fan of the movie probably knows this species thanks to director Steven Spielberg. Spielberg made it famous by depicting it as quite a cute, curious, shorter-than-a-human dinosaur with large neck frills that could kill people by spewing venom into their eyes.
While it’s a memorable scene, it turns out that the depiction of Dilophosaurus is nowhere near reality. What kind of species is a Dilophosaurus then? Did it really spit venom? What did it look like? What did it eat? These are only some of the questions we’ll answer in this list of incredible Dilophosaurus facts.

Facts About The Real Life Dilophosaurus
Among the seven species that are featured in 'Jurassic Park', the Dilophosaurus, the dinosaur with neck frill that we all know and love, was one of the two that actually lived during the early Jurassic period. The other was the Brachiosaurus. However, there are questions regarding the accuracy of the movie in depicting the Dilophosaurus. So, what is fiction and what is not?
1. No, the Dilophosaurus dinosaur didn’t spit poison. This depiction came from pure imagination of Michael Crichton, the writer of the novel that the 'Jurassic Park' movie is based on. There’s no evidence that any dinosaur from the Mesozoic Era used poison when attacking or defending itself.
2. Unlike what the movie shows when the Dilophosaurus expands its vibrating fins, the dinosaur species didn’t have these in real life since. There’s no evidence that any carnivorous specifies of a dinosaur with a neck frill existed. What the movie got right though are its bony head crests.
3. The neck frills were given to the movie version of the Dilophosaurus dinosaur so that the audience could distinguish the species from the Velociraptor.
4. The Dilophosaurus shown in the film is short and tiny, which is the complete opposite of what researchers believe to be the size of this species. The real Dilophosaurus' height was over 20 feet and the weight was 1,000 pounds.
5. In 'Jurassic Park' , the characters came across a lone Dilophosaurus. Compared to reality, this was highly unlikely because Dilophosaurus dinosaurs belonged to packs, meaning they lived and hunted as a group.
Facts About The Dilophosaurus’ Diet And Dilophosaurus' Habitat
With the dilophosaurus' weight and height, you'd think that it would be easy for them to prey on anything that moves. But, there were some considerations regarding their eating habits.
6. The Dilophosaurus loved to eat meat. However, hunting would’ve been difficult for them because their jaws were loosely attached. If they did hunt, they targeted only small preys using their clawed arms and legs.
7. Because using their teeth to kill would’ve been difficult, the Dilophosaurus were more likely scavengers, eating out of carcasses.
8. With teeth like needles, Dilophosaurus may have been a fish-eater. They’re able to catch fish by puncturing them, and thanks to their high-set nostrils, they’re able to keep their head above the water.
Facts About Dilophosaurus’ Skeleton, Discovery And Classification
Why was the Dilophosaurus given this name? How was it classified? When was it discovered? Read on!
9. It was in '40s when the first Dilophosaurus fossil was found in Arizona in the United States. Sam Welles discovered the remains in 1942 when Navajo Jesse Williams led him, Bill Rush and Ed Kott to the site.
10. All in all, three sets of Dilophosaurus skeletons have been discovered in Arizona. They are now housed at the Museum of Palaeontology at the University of California.
11. The Dilophosaurus lived during the early Jurassic period, some 193 million years ago. These early Jurassic dinosaurs are believed to be a recent descendant of the first true dinosaurs, which existed during the Triassic period 230 million years ago.
12. The classification of the Dilophosaurus isn’t certain, given the wide range of small-to-medium-sized theropod dinosaurs back then. Scientists have placed the Dilophosaurus into different classifications, ranging from a ceratosaur to coelophysis.
14. The name Dilophosaurus was based on their head crests, which they're known for. These paired crests were located at the top of the Dilophosaurus' skull. No one knows for sure what these crests were used for.
15. Some scientists believe the crests were used for mating purposes, showing whether males were attracted to the female dinosaurs. Others, meanwhile, believe that the crests were used to identify each other since Dilophosaurus hunted as a pack.
16. The name Dilophosaurus is made of words of Greek origin that mean “two” “crest” and “lizard”. Therefore, Dilophosaurus means "two-crested lizard".
17. Megalosaurus wetherilli was the former name of the Dilophosaurus. This is because scientists placed different meat-eating dinosaurs under the category of Megalosaurus.
19. The only specimens of the Dilophosaurus that have been discovered so far were found in Southwest America. However, footprints suspected of belonging to the species were seen in Connecticut and Massachusetts in the 1840s.
20. The tracks were named Eubrontes giganteus since it’s unsure whether they’re from the Dilophosaurus.
Facts About Dilophosaurus Traits And Characteristics
From the Dilophosaurus' size to their weight to how they carry themselves, this species had certain traits and characteristics that allowed them to adapt to their habitat.
21. Being part of the predatory theropod dinosaur, the Dilophosaurus might have been warm-blooded like human beings. Unfortunately at the moment we cannot confirm this, more research is needed.
22. Despite their huge weight, the Dilophosaurus didn’t have trouble carrying themselves. This means that they didn’t suffer from stress fractures when they walked or hunted.
23. The Dilophosaurus had weak teeth at the back of the upper jaw and firmer teeth on the front. This is why they may not have had the capacity to kill large preys using their mouth.
24. Based on footprints found in Utah, the Dilophosaurus sat like a bird. Their prints showed impressions as if they were squatting down like a bird.
25. Based on imprints discovered in mud, it is possible that the Dilophosaurus had feathers.
Facts About The Dilophosaurus’ Fighting Style
Dinosaurs are known to be scary and terrifying, considering their appearances and how they are portrayed in 'Jurassic Park'. But like any other species, the Dilophosaurus had its own way of attacking an enemy and defending itself.
26. Likened to an ostrich, the Dilophosaurus was active and bipedal. They moved fast, which was an advantage when hunting.
27. They have powerful and flexible forelimbs, which could be used to attack and defend.
28. With strong hands, they could grasp and slash their enemy’s neck. They can also bounce on their tail as they fought an enemy.
29. There’s a kink in their upper jaw that can also grip or hold down prey.
