Dilophosaurus is as tall as you! (Except if you are still alive as Robert Wadlow!)
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.
What dinosaur use to eat Dilophosaurus dinosaurs
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.

Fossils
Yes, all dinosaurs do
Dilophosaurus was 23 feet long and weighed 1,100 to 2,200 lb, depending on the weight estimate you use. Velociraptor was only 6 feet long, 2 feet tall, and weighed about 33 lb. If you put them together, the Velociraptor might be able to escape. If it couldn't escape, it would probably be killed and devoured by the Dilophosaurus.
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.
