Probably not pennaceous or filamentous feathers, but some may have had quills or bristles. |

We have scaly skin prints from Argentina. However, if said scales are reticulae (i.e. bird foot scales, now thought to be derived from feathers), then they definitely evolved from feathered ancestors, and probably had sparse feathers like modern elephants and rhinos have sparse fur. |

Could Albertosaurus and T. rex have been direct descendants of Gorgosaurus and Daspletosaurus, respectively? |

So far the Daspletosaurus -> Tyrannosaurus ancestry is disputed. Currie says that Daspletosaurus is more closely related to Asian tyrannosaurids. Not to mention Daspletosaurus' classification isn't in good shape at the moment. The other one is, IMO, a possiblity, considering how closely related the two genera are described, though I doubt it can be said for sure. Plus, there's a few million years gap between the two, something 'inbetween' would be nice. |

ive heard Das is more basal once Lythronax was found, and Lythro is believed to be a relative of T.rex as of now. |

Were there any theropod that could have been as inteligent as modern crows? I've read you guys said that troodontids and dromeosaurs had the intelligence of chicken, so i'm just curious if any other small theropod could have been as inteligents as modern crows.

Could venomous theropods actually have existed? I know that neither of the two genera that have been proposed to be venomous (Dilophosaurus and Sinornithosaurus) were likely to be so, but what about some other theropod? |

I doubt that venomous theropods existed, afterall venom is modified saliva and Modern Archosaurs don't have saliva

Well, if such animal did exhist, we don't have the proof yet. |

So yes. And if someone watched Dinosaur Revolution, then they should have an idea what being smacked by such tail would result with - even if the show was a bit exaggerated here and there, that part wasn't Sci-fi. Of course the range of motion of the whole tail wasn't the greatest, but probably enough to give the animal some protection. |

There are birds, which eat poisonous beetles and, instead of getting ill, they somehow acquire the toxin to their feathers and skin, becoming poisonous themselves. I don't know, though, if Mesozoic theropods already have had substances needed for doing something like this, but considering that similar adaptations exist in poison dart frogs and some nudibranchs, these might have been created independently from today birds' ones. So we don't know about poisonous dinosaurs, but, as Furka said, there isn't a high possibility of truly venomous ones. Edited by Swimming Spaghetti Monster, May 13 2014, 02:10 PM.

Me again: - In what kind of environment lived the prenocephale? |

It lived in the Nemegt Formation, so most likely a sparsely forested oasis environment. |
