I favor the postosuchus as it is more powerful, has a deadly bite, and is well armored. And yes I know that big cat's can penetrate the hides of crocodilians but it doesn't change the fact that postosuchus has the ability to sustain far more damage than the tiger could.
I would think that stability advantage of a quadruped is lost when the animal's forearms are being used to grapple, rather than support its weight.

I would think that stability advantage of a quadruped is lost when the animal's forearms are being used to grapple, rather than support its weight. I don't think postosuchus could land a decent bite. Considering its long back and short front legs and long heavy tail, its agility probably isn't near the level of the tiger. Big cats have superb reflexes, further decreasing the postosuchus' chances of landing a meaning bite. I find it more likely for the tiger to knock it over. |

It seems that the holotype might not be representative of a full grown adult as there's an specimen (TTU-P 9235) 25% larger in linear dimensions (therefore twice as heavy with a ~70cm long skull).

Cats are fast but not to the point where they can dodge all the attacks of another terrestial animal in a prolonged fight, and postosuchus's thick hide and size is certainly going to take a tiger a long time to overcome if at all.

Oh, then I definitely fancy the Postosuchus' chances here then. As if it wouldn't stand a chance at parity, let alone if it's apparently twice as big as one roughly the size of a tiger. |

I've always supported felines over reptiles, even though I like reptiles more. Their agility and activity levels just seem like such a huge advantage. At similar sizes I see the tiger winning ~65-70% of the time.

Cats are explosive, ambush hunters. So, no. It probably can't dodge all attacks in a prolonged fight, due to its low stamina. However, a tiger has superior agility and excellent leaping skills. I see the tiger being able to tackle the postosuchus to the ground, or leaping on it before it runs out of energy. |

There is no reason to believe why a tiger would have less stamina than a postosuchus.

Here's Prehistoric Cat's/Megafelis Fatalis' Postosuchus vs Tiger size comparison, modified to have another Postosuchus specimen(TTU-P 9235) ~125% the dimensions of the holotype, as a red silhouette.  |

A 6 to 7.25 m rauisuchian? This would be a serious contender for the title largest rauisuchian.

Even using the smaller size estimate, I would still favor the postosuchus here. The tiger would need to land a good bite on its throat to be able to kill it (that is how felids kill), whereas the postosuchus could likely cause a good deal of trauma to the tiger with a well-placed bite anywhere, as its dentition was designed to kill with immense trauma as opposed to a well-placed puncturing bite

creature386Weinbaum (2013) estimates appear to be based on TTU-P 9002, a 70% complete skeleton that they claim would have been 3.5-4m long but looking at the measurements between that specimen and the holotype in the table 7A.1 it appears to be 80% the size on average rather than the ~67% necessary to estimate 5-6m for the holotype, the difference between the length of their ischia is that big but all other measurements are much closer. So 5-6m for the holotype are not realistic, in fact scaling their reconstructions to match its measurements it ends up with a head-body length of 2m and an axial length of 4.4m (tail length ~54% of TL), that'll make the big one 2.5m in head-body length and 5.5m in axial length.

OK, so it looks like it does not change a lot for this matchup, as the larger specimen seems to fit in the 5 to 6 m range. |

creature386It does change things, that size chart in broly's post is not depicting them at the sizes claimed by Weinbaum (2013) but at 4.4m and 5.5m in length, a true 7m rauisuchid with those proportions will be looking at the guy in the eyes.
