| Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike.

Surprise! Bet you thought this was some kid who saw Jurassic Park and thought that was what Dilophosaurus was like. Well no, it's me. I've been watching a documentary on Komodo Dragons and how they hunt. They have very weak jaws with very long sharp teeth and a fragile skull, which got be thinking about Dilophosaurus, which from what I know was similar. Perhaps like the dragon, Dilophosaurus would chase down prey, snap at it, tear the flesh with it's jaws and work venom into it's prey. Any thoughts? |

You know, I always puzzled on it having weak jaws yet being a reasonably sized carnivore. So yes, venom/poison is reasonable. Though what kind of venom/poison? |

You are not merely outside the law, you are outside humanity. Neither age nor sex shall save you and yours. You shall die, but first you shall taste the agony of your wife, your sister, your sons and daughters, even those in the cradle! Before your eyes the wounded man shall be taken out of the ambulance and hacked with bayonets or knocked down with the butt end of a rifle. He shall be dragged living by his broken leg or bleeding arm and flung like a suffering, groaning bundle of refuse into the gutter. Death! Death! Death!" | |

Well the dragons use an anticoagulant, but I don't see any way to could prove what the venom was. |

Maybe it didn't use venom at all. Maybe it's strategy was to maul its prey and track it while it died of natural infections in the wound. Worked well for us 10,000 years ago. |

We should all aspire to die surrounded by our dearest friends. Just like Julius Caesar. "The Lord Universe said: 'The same fate I have given to all things from stones to stars, that one day they shall become naught but memories aloft upon the winds of time. From dust all was born, and to dust all shall return.' He then looked upon His greatest creation, life, and pitied them, for unlike stars and stones they would soon learn of this fate and despair in the futility of their own existence. And so the Lord Universe decided to give life two gifts to save them from this despair. The first of these gifts was the soul, that life might more readily accept their fate, and the second was fear, that they might in time learn to avoid it altogether." - Excerpt from a Chanagwan creation myth, Legends and Folklore of the Planet Ghar, collected and published by Yieju Bai'an, explorer from the Celestial Commonwealth of Qonming Tree That Owns Itself

Not infections, chasing until it's exhausted. That kind of hunting requires tracking, but I suppose smell could work. Also, I don't know of any animal that was weaponised it's mouth bacteria. |

Reports of venomous dinosaurs are greatly exaggerated First let's do some superficial comparative anatomy ![]() You'll see that behind the eye the Komodo skull is loosely built whereas in the case of Dilopho' there are solid bars of bone linking the cheek area to the back and top of the skull. The skull itself is taller than that of V. komodoensis and I see little reason to consider the jaw weak: compare with Allosaurus the proportions of the jaw and back of the head are reasonably similar which indicates that while not on par with Tyrannosaurus is wasn't a pushover either. Also the venom glands in lizards are seated deep within lips which is doubtful dinosaurs ever had given the phylogenetic bracket and how archosaurs develop beaked forms at the drop of hat which suggests what they had covering their mouth margins wasn't the same thing as what lepidosaurs have. One option for predatory techniques could be hit and run tactics much like Great Whites do with seals. Or being axe-crazy as Bakker would have it, http://www.mnhn.ul.pt/geologia/gaia/10.pdf |

Are you plausible?

I've always thought that thin area at the front of the dilophosaur upper jaw (as seen in the picture) seemed a little flimsy. I think there's some Darwinian sense in supplementing what could potentially be a weak bite with some chemical and/or bacterial "venom." Hey, maybe they actually "spit" their venom or something? And maybe had some sort of warning signal like a rattle, or... yeah, a great big frill! What a cool and interesting idea!

Got any proof of that? Anyone done any studies? Because aside from them having nasty mouths, like most predators it just seems to be people repeating a hypotheses. I think the weird hook thing is supposed to be the weak part, I honestly don't know that much about these dinosaurs. |

I thought it was a known fact that Komodos use not venom, but bacteria. It cant be that hard to find out and it has been stated many times. And dracontes you seem to be a good dino nerd, I'll take your word for it. But I've grown up with dino encyclopedias saying dilos had weak jaws. |

Nope, it was recently proved that dragons have venom. Nothing either way for mouth bacteria as of yet. |

Why does Dilophosaurus have to have venom, when it's got sharp teeth? (Maybe the notch is for a large tooth. Sabre-toothed dinos... *Drools*) I'd say that the teeth could probably pierce windpipes, major blood vessels... Dilo is probably an accomplished predator in the same way that all the others are. |

It does not need venom, it's a possibility. And if it had sabre teeth then it would have sabre teeth. Sabre teeth are the most obvious sign and animal had sabre teeth. |

I was just thinking of how awesome a Dilo would be with sabre-teeth... Even if it doesn't. Yea. I just do that when people talk about weak-jawed theropods. |
