Did dilophosaurus really spit

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.
