I always assumed they did (though not when charging prey like people seem to think) but some stuff I came across recently called that into question for me. For example I don't think Saurian's T. rex has a roar. Is there evidence for or against it? And is it even a rational assumption? If we look at today's large carnivores, some territorial species like Panthera cats roar to establish territory (except for leopards of course.) Other territorial animals like dogs and certain primates also make use of long-range vocalization. They also use them for contact calls over long distances in the social species. On the flip side, bears are not particularly territorial, and they don't have much of a roar, at least nothing like a lion's. I figure at this point that T. rex was both social to an extent and territorial. So by all accounts I would think it has a purpose for roaring. Thoughts? |

Sure it roared, though not in the way as mammals do, no, but like gators and ratites might. |

Depends on how one defines a "roar". From a scientific perspective only big cats roar, from a literary perspective any loud sound can be called a roar. Even if only because it makes people reevaluate the terrible stock sound effects that are still being reused, I would say a definite no. |

Exactly! Mammals use their larynx, birds make sounds with their syrinx, and for crocs I'm not sure. It would certainly sound different from a mammalian roar. |

Yeah it could roar. It's been found that crocodilians do in fact use a larynx to bellow (the test involved something about giving an alligator helium/air mix). And the fact that both modern crocodilians and birds are VERY vocal and make lower pitched and LOUDER calls compared to similar sized mammals, it's more than reasonable to suspect that T. rex not only had some kind of vocalisation, but a huge range of them. And, more critical to this topic, many of them were likely really REALLY loud. |

Theropods in general more than likely had a syrinx or a syrinx-like structure, being related to birds. if you want to hear what a T-rex may have sounded like, try using some sound modification software and mess around with different bird calls, until you create something that you could consider a roar. |

Birds also use their larynx, especially non-Neoave forms like ratites and waterfowl |

From what I've read, it seems the basal condition for birds is having a syrinx, but some derived forms like New World vultures have lost theirs. The next question then would be when did the syrinx arise? Also I assume that any non-mammalian larynxes kicking around would be a result of convergent evolution, or..? |

Actually, no. The larynx is fairly basal in tetrapods, or at least amniotes. It's just that mammals have vocal folds on their larynx and the other groups don't, or if they do, those have evolved independently. |

Even crocodilians, which do produce vocal calls using their larynx, do so in a different manner than mammals. |

The sirynx appears to be an entirely neognath invention |
