Hello everyone, Paleontologists discovered that Mapusaurus hunted in gangs in order to take down Argentinosaurus. Now I think that almost every predator that lived together with a giant sauropod must have hunted in gangs. Sauroposeidon was the biggest herbivore in America in the early Cretaceous, the Apex-predator was Acrocanthosaurus. Acrocanthosaurus must have hunted in gangs, otherwise full-grown Sauroposeidon wouldn't have any natural enemies. Or Acrocanthosaurus only preyed on juveniles... Now the question is: Were most Theropods capable of hunting in gangs? They were very primitive after all. Tell me what you think about this! Best regards, Oxalaia |

And that's why sauropods got so huge. A fully grown giant sauropod didn't HAVE any natural predators. The reason why theit population was kept under control was because they where very vulnerable at young ages. |

There is some limited evidence that some large theropods may have lived in groups of some sort. However, that does not mean to say that they actively hunted in groups, packs or 'gangs'. Something else to keep in mind is that even the largest sauropods were small when young. And there is often at least one other species of sauropod around at the time that is considerably smaller than the giant. |

Theropods were not "very primitive". That doesn’t mean they must necessarily have hunted in groups, but I see no reason why some of them shouldn’t have been cooperative hunters. There is some circumstantial evidence for a number of taxa, even tough it’s not unambiguous proof. Behaviour isn’t as rigid as some people seem to think, even those that do not usually cooperate can do so under certain conditions. If there is cooperative hunters in actinopterygians and crocodiles, I don’t see why non-avian theropods should not have been capable of it. |

Considering that glorified dinosaurs (birds) do not for cooperative "packs" very often (although I don't know for sure), and that Crocodilians only form "packs" when there is an abundance of food, I'd say it is safe to assume that Theropods were solitary for most of the year, only during the breeding season or during mass herbivore die-offs, would they form what could be loosely called "packs". |

Most theropods like carnosaurs needed to be in groups, since they hunted much karger prey like sauropods. |

Carnosaur as in any large theropod, or Carnosaur as in Allosaurus and relatives? Either way, they wouldn't have to hunt only large prey, Lions only take on Elphants when they know they have the advantage. They usually stick to smaller prey, such as Buffalos and Antelopes. A full grown Apatosaurus had nothing to fear aside from illness and injury, large theropods most likely targeted baby sauropods and ornithopods. Maybe they'd get lucky and kill a stegosaur, but adult sauropods were a luxury most theropods would never get to enjoy. |

You know good and well what I'm talking about.
Bad analogy, for many reasons. 1. Lions often hunt in the things called prides, your counter argument failed. 2. Buffalo aren't small prey. They weigh up to a ton, 4 times of your lions. 3. And lions will take down elephants and buffalos to. 4 it's shy the carnosaurs hunted in PACKS. To bring down much larger animals, animals they couldn't even dream of hunting. |

Allosaurusatrox: I think the answer to the first question is obvious, because there is only one, and (only) that one makes sense in the context it was used in. As for the second part, I definitely agree that the notion of carnosaurs exclusively, or even mostly, preying on large sauropods is utter BS. I don't even know where it originated. Obviously the media like showing them while attacking a much larger sauropod, but to reasonable people it should go without saying that they didn't do that all the time. Even the most capable macropredators in the extant world (komodo dragons, wolves, eagles, big cats) do not primarily prey on animals that are orders or magnitude larger than themselves. I see no reason why it would be different with theropods, were, for most apex predators, normal prey sizes would probably tend to be between half and twice their own size, likely in the higher region for carnosaurs in whose ecosystem sauropods were dominant, aand lower for tyrannosaurs that mostly coexisted with smaller herbivores. Nonetheless, adult sauropods were not impervious to attack. Carnosaurs in particular were just as perfectly adapted for killing larger prey as oras are, which are themselves no larger than humans but capable of killing adult water buffalo (the second-largest extant bovid). Large carnosaurs would definitely be a treat to adult sauropods, all the more so if they hunted in groups. Edited by theropod, May 25 2015, 08:16 AM.

Hello theropod, nice to talk to you.
He knows the awnswer to that complete nonsense.
Are you saying I'm talking BS?!? I never stated that it was there primary target, but I know they hunted them every now and then. You agree? |

So then by big cats you also include fat house cats? See how a generic term looks? Carnosaur should not be used as a catch-all term. It should only be used in its true phylogenetic sense. |

What are you babbling about now?
I picked a random family of theropods. I an not trying to make them represent all theropods. |

Carnosaur was historically used to reffer to ALL large theropods. And I am not babbling. |

Big cat = Panthera, the house cat is Felis. So no, no fat house cats. |
