No.![]() Dinosaur ears fit snugly between the quadratojugal/quadrate and the muscle that opens the lower jaw (which stretches from the rear of the surangular to the paretial/squamosal). |

1. There is no biological reason why they couldn't have been, to my knowledge. However, as there are NO other bioluminescent tetrapods that we know of, the likelihood is pretty much nil. 2. I don't see why they couldn't- Hadrosaurs are known for being able to rear up on their hind legs, and their forelegs are very much like hooves. 3. Carnotaurus. All the sources I've seen say 40kph, but this seems way too small for an animal so adapted for running... I'm guessing more like 80 or 100 kph, but I'm no expert, so DO NOT take my word for it. |

It wasn't 40kph. Carnotaurus was thought to run at 40-50 miles per hour, IIRC. |

That makes more sense. The only source I could find said 40 kilometers. So, about 65 to 80 kph.

Holy crap. That makes it around 70-80 kph. |

What did it need that speed for? |

My best guess would be that abelisaurids were pursuit predators rather than ambush predators like most other theropods appear to have been. |

Perhaps it hunts like cheetah? Going after small and swift preys that is even slower than itself... I could see something like Hypsilophodont or similar ornithopods in its environment being its main prey.... |

It wasn't hunting big animals, I can tell ye that much. Small head, small teeth, weak jaws, wasn't particularly large etc. But we know it was well adapted to allosaurus-like axeblows with its head. So there's that. And we also know that, while it was very good in a straight line, it probably had atrocious cornering. Annoyingly, we don't even know what it lived with. Carnotaurus is the only reasonably known dinosaur from its formation. And even then, everything we know about Carnotaurus, and I mean *everything*, including its rough, wrinkly skin, is known from one specimen. |

@Mathius: Your theory sounds right. I even remember seeing some art that depicts that.

Is there any reason as to why it evolved to be so bad at turning? Cheetahs are particularly good at turning when sprinting because of their long tails.

I'm not sure about that. That's a very good question. Also here's the art: http://chrismasna.deviantart.com/art/Hello-I-am-the-Devil-336536001 |
