Ya, no except that part. That's ridiculous. By the way, what's the Spinosaurus bite force? It had crocodile like jaws, so I'm assuming it would have a pretty strong bite, right? Probably around 3 tons, and not exceeding 4.5 tons. The jaws of spinosaurus are crocodilian-like, but they are not necessarily crocodile-like. Nevertheless, the skull is still more robust than that of most other theropods. P.S. facking lol Most crocodilians have impressive bite forces,I wouldnt be surprised if spino's was respectable.

Giganotosaurus is actually a very good candidate for having a higher bite force than T-rex. Here is a comparative table from the study: What actually surprised me is the very high bite force Allosaurus achieves. The paper mentions that this due to very high mechanical advantage. This make Giganotosaurus a very real contender for the most powerfull bite of a land vertebrate. In the suplementary material the Aloosaurus is listed with askll length of 70cm. If we assume isometric scaling, a Giganotosaurus with a 1.95m skull wold have a maximum bite force of 67700N. Source: K. T. Bates and P. L. Falkingham (2012).

An allosaurus with a 39,000 n bite force? I would seriously question the validity of that. As for giganotosaurus bite force: 1. Animals get weaker pound for pound as they get larger. 2. Giganotosaurus' skull is built for a wide gape to take on large animals. The trade-off is that its bite force is greatly diminished. Therefore, I wouldn't be surprised if giganotosaurus' bite were the same as allosaurus'. 3. Common sense. Neither giganotosaurus' nor allosaurus' skull is very robust, and both lacked fused nasals. The fenestra are large and the bone isn't thick.

No, I don't trust this at all. Other studies have found allosaurus to have a significantly lower bite force than is described here.

The similarity of crocidialian and Spinosaurid jaws in mainly dental, the actual skull structures are quite different. Crocodiles having strong bites is no reason top believe Spinodsuarids did(and I'm not saying they didn't, just criticizing the crocodile comparison).

www.nature.com/nature/journal/v409/n6823/full/4091033a0.htmlUnfortunately, it's not complete, but wikipedia says the following (and cites this source): "Similar conclusions were drawn by another study using finite element analysis on an Allosaurus skull. According to their biomechanical analysis, the skull was very strong but had a relatively small bite force. By using jaw muscles only, it could produce a bite force of 805 to 2,148 N, less than the values for alligators (13,000 N), lions (4,167 N), and leopards (2,268 N), but the skull could withstand nearly 55,500 N of vertical force against the tooth row. The authors suggested that Allosaurus used its skull like a hatchet against prey, attacking open-mouthed, slashing flesh with its teeth, and tearing it away without splintering bones, unlike Tyrannosaurus, which is thought to have been capable of damaging bones. They also suggested that the architecture of the skull could have permitted the use of different strategies against different prey; the skull was light enough to allow attacks on smaller and more agile ornithopods, but strong enough for high-impact ambush attacks against larger prey like stegosaurids and sauropods." It does seem to be something of an underestimate, but an allosaurus with a 5 ton bite force is rather ridiculous. If that's so, Tyrannosaurus' bite would be 20 tons or something. digital.csic.es/bitstream/10261/22490/1/102.pdfThis document states that allosaurus' jaw muscles allowed for a wider gape, at the expense of jaw power. I wouldn't be surprised if this applied even more so in giganotosaurus' case.

^Well the chevron doesn't work out but yes, Stan took a tooth to the skull and still survived.

This is why I scoff at the idea of another large theropod killing a T.rex. We rarely find such intense injuries on other skeletons, if a Tyrannosaur can survive the bite of one of its own kind to the skull, surely the bite of an inferior biter like Spino or Giganotosaurus is nothing to worry about. Spino's fragile skull would be crushed under such power, and even Giganotosaurus would be virtually helpless against such a bite. The only way to beat a rex would be to do what it's doing but do it better. Be robust, deadly, and durable.
