Ever since Jurassic Park, many people have thought that the Dilophosaurus (meaning double-crested lizard) was a three-foot-tall dinosaur that had rather large, retractable neck frills that would puff out whenever it felt threatened by something and spat blinding poison that looked like a black or a very dark brown tar-like substance. Michael Crichton, the author of Jurassic Park, just sized it down a little so the audience would not get confused with the Velociraptors.
To tell you the truth, there is not much evidence about the neck frills.
However, it did spit, but it did not spit blinding poison of any kind. I am not very sure of what it spat, though. It is possible that it may have had some sort of special instinct with its spit glands. Ours are located under our tongues, as you can see, if you gather some spit, you may notice that it feels like it is coming from under your tongue, but maybe the Dilophosaurus had its spit glands in a different spot than ours.
In that case, it is not poisonous, but if you mean poisonous by touch, no, it was not poisonous.
Dilophosaurus did not spit. Jurassic Park may have shown that but Jurassic Park's Dilophosaurus was completely false. When Dilophosaurus was discovered he was 20 feet long and he did not have a frill. There is no proof that he spit poison. Dilophosaurus was probably warm blooded and may have weighed 1,000 pounds.

Dilophosaurus is as tall as you! (Except if you are still alive as Robert Wadlow!)

Allosaurus, Ornitholestes, Dilophosaurus
It's never revealed how many Dilophosaurus were in the film version, but there was definatley more than one, because on the tour it talks about a 'herd' of Dilophosaurus.
Okey. Lets size 'em up. Dilophosaurus and Ceratosaurus were both 23 feet long, but cerato out-wieghed its rival by 1,000 pounds. Dilophosaurus was faster and smater, but Ceratosaurus was stronger and had much larger teeth and jaws. So who would come ontop? In my opinion, Ceratosaurus.
Allosaurus, Ornitholestes, Dilophosaurus
