Just wondering how aggressive Spinosaurus was. He being a fish eater caters to most folks him not being that aggressive. I always wonder and ponder on the question. Im pretty confident that Spino fought over territorial disputes and mates. Opinions? |

There is none from my knowledge. Even if there is data, we wouldn't have much of a basis for it. |

There is no data. We can only guess. I personally think spinosaurid aggression was similar to ursine aggression. |

Basically this. Though, if I had to guess, it would have been aggressive when it needed to be (eg: directly competing with other large carnivores). Though, it would have been fairly non-aggressive if it wasn't in such a situation. Edited by Ausar, Aug 23 2013, 12:43 AM.

It's worth noting most amphibious fish eating animals are really good at destroying animals when they want to. We all know about crocs, otters, bears, etc, and try talking to someone who's done wildlife rehab, fish eating birds can wreck you if they want to. |

We can only guess; I think it was just as aggresive as any other meat eaters. |

Nobody will even know, it is absolutely untestable. Maybe future finds of pathologies can give us a bit of an idea though, at the moment these are strangely lacking. |

Aggression is entirely behavioral; frankly, there is little way to know whether or not an extinct animal was aggressive or not. The only way to remotely confirm this is through fossil evidence of conflict, and even that does not determine how aggressive an animal is by-nature (for all we know, it could merely be territorial, but not completely aggressive) And given the fish-eating nature and highly precision-based morphology of the creature, docility was likely one of its greater assets compared to something that would have had no problem in face-to-face fighting such as tyrannosaurus or a ceratopsian |

Territoriality is a form of aggression. But it’s questionable at best how well this correlates with functional morphology. Take swans or seagulls for example. They aren't really formidable, but they can be very aggressive. Edited by theropod, Nov 3 2014, 02:47 AM.

Spinosaurus being orimarily a fish eater is used too much as an argument. I wouldn't say aggression is something really important. When an animal attacks another animal it doesn't have to be aggressive to do it. It just has to be hungry. Aggression is about attacking another animal without intending to consume it. It can greatly differ from specimen to specimen. All species of cognitive animals have this. |

It's worth noting though that a lot of animals attack completely differently in an aggressive attack than in a predatory one. The best example I can think of is big snakes. If you're AGGRESSIVELY bitten, you'll have some puncture wounds, but be fine. If you're bitten in a predatory manner and no ones around to save you, you're probably dead. |
