Dilophosaurus was a fast-moving bipedal predator that had a double crest on its head. Although it was depicted as spitting poison in the Jurassic Park movie, there is no fossil evidence that it did so (it was also pictured far too small, with an incorrect skull, and with a frill it did not have). Sadly this is another entry that got removed because of space limitations in my book Thunder Lizards! The first example is from artist Bryan Baugh (cryptlogic.net), the second is from artist Brett Booth. I supplied the coloring. I also inked the Booth piece. Dilophosaurus will definately be in my next dino book, but for now you can view it right here; sort of like a deleted scene from a dvd.
