中国古生物网的资料已经没法在用了，这里将引用来自维基百科提供的信息。

轻插，直播？

先来看维基百科的原文是如何描述的：
[1].双脊龙曾多次出现在大众文化之中，最著名的是在电影《侏罗纪公园》（Jurassic Park）中被描述为会喷毒液的恐龙。此外还在众多的电玩游戏中登场。但这些作品中的双脊龙形象跟现实有很大的出入。
[2].双脊龙出现在1993年的电影《侏罗纪公园》（Jurassic Park）与同名原著小说《侏罗纪公园》之中。在电影版本中，双脊龙的颈部拥有可收缩的皱折，类似褶伞蜥，而且能射出致盲毒液，使猎物失明且瘫痪，类似喷毒眼镜蛇。但没有证据可以显示双脊龙有这种行为。电影版的导演史蒂芬·史匹柏将双脊龙的体型缩减，成为身长1.5米，高度0.9米的小型恐龙。在电影的引述中则将这小型的双脊龙解释为幼年个体。

如果还有异议，英文版是这么描述的。
Dilophosaurus is prominently featured in both Michael Crichton's 1990 novel Jurassic Park and its 1993 movie adaptation. It is depicted spitting blinding poison, aiming for the eyes to blind and paralyze its prey (much like a spitting cobra); in the film, it also has a retractable neck frill around its neck (much like a frill-necked lizard). There is no evidence to support either the frill or the venom spitting, which was acknowledged by Crichton as creative license.In the film, Steven Spielberg also reduced the size of Dilophosaurus to 3 feet (0.91 m) tall and 5 feet (1.5 m) long in order to avoid confusion with the velociraptors.

关于双脊龙在《侏罗纪公园》中的错误形象，两位是这样描述的：
Dilophosaurus
The Dilophosaurus was probably not endowed with neck frill (borrowed from Australian frilled lizard) nor could spit venomous saliva (though its bite could have been poisonous due to bacteria developing in rotting meat in theropoddental serrations; bacterial toxins help the Komodo dragon in killing their prey).
If Dilophosaurus did have a frill, we would know about it. There would be fossil evidence of bones or some other rigid structure required to hold the frill up and there would be markings on the bones of the neck indicating where muscles could attach that would be required to move the frill up and down. We don't see either of these.
Dilophosaurus was too small.
If Dilophosaurus indeed had an expandable skin collar around its neck (and that's total speculation), it certainly wouldn't have deployed it when facing a prospective meal (Nedry). That kind of display is more for intimidating prospective competitors (such as for mates or territory). Why would a carnivore try to intimidate its next meal?
One little side note - When Nedry and the Dilophosaurus are studying each other, Nedry pulls the hood of his raincoat over his head, which may parallel the hood-flaring of the Dilophosaurus and trigger an intimidation response. Or maybe I just have too much time on my hands...
