Allosaurus: Yes, but I would like to note that the person who requests a thread is expected to contribute to the thread, with sources, links to papers and abstracts. We highly encourage our users to do this, so thank you in advance.

Also notice how its skull, seen from the top view, is comparable to Tarbosaurus bataar in robustness, which also doesn't have a very robust skull. Moreover, it doesn't have very imprssive surangular or angular bones, so I don't think it really has a very strong bite proportionally, but obviously deadlier due to the far longer teeth. We also shouldn't underrate Utahraptor ostrommaysorum's biteforc. According to Longrich and Currie (2009), both Deinonychus antirrhopus and Utahraptor ostrommaysorum are in the Eudromaeosauria, and since they have similar builds, they can be compared. Well, this paper shows that Deinonychus antirrhopus had a very strong bite.
"Bite force estimates for Deinonychus were first produced in 2005, based on reconstructed jaw musculature. This study concluded that Deinonychus likely had a maximum bite force only 15% that of the modern American Alligator. A 2010 study by Paul Gignac and colleagues attempted to estimate the bite force based directly on newly discovered Deinonychus tooth puncture marks in the bones of a Tenontosaurus. These puncture marks came from a large individual, and provided the first evidence that large Deinonychus could bite through bone. Using the tooth marks, Gignac's team were able to determine that the bite force of Deinonychus was significantly higher than earlier studies had estimated by biomechanical studies alone. They found the bite force of Deinonychus to be between 4,100 and 8,200 newtons, greater than living carnivorous mammals including the hyena, and equivalent to a similarly sized alligator."
So if Deinonychus antirrhopus had a strong bite, I can easily see Utahraptor ostrommaysorum also having a very strong bite.
The angular and Surangular are not jesus dude, other parts of the skull matter as well. Not only that Ceratosaurus nasicornis has proven to have a bite force comparable to the larger allosaurus. Also Ceratosaurus nasicornis is a possible sub adult so it might have an experience disadvantage. I am leaning towards Ceratosaurus nasicornis for this one still but this posts shows both weaknesses and strengths.

They are the most important parts though, hence the fact the jaw-shutting muscles are mostly there. The upper part of the skull is "static", so it means the lower jaw presses an object against the upper part of the skull. Also, remember that Utahraptor ostrommaysorum should have a biteforce superior to that of a large Alligator.
They aren't really the most important parts, the neck and teeth play an equally important part and the entire strength of the skull comes into priority. All of it together is requires not just the "MLJ PR0 ANGULAR AND SURANGULAR"

The teeth only equal AREA (a small one at that, given the fact they are sharp), which is kinda irrelevant to total biteforce, it only helps a lot when you use PSI. The strength of the skull, which I assume you meant hardness (what else would that be anyway?), only matters when it is about the own skull standing the biteforce, which all theropods obviously have adaptations to. The neck muscles do play a quite important role, but they are mostly used to move the neck structure rather than giving it biteforce, although they do KINDA help it. The muscles attached to both angular and surangular parts of the skull actually play important roles, for obvious reasons.
Hatzegopteryx: That's not even the beginning, the whole forum is disturbingly lethargic.

Spinosaurus Maroccanus: I'm quite surprised how no one has touched the Argentina 97ma thread

Hatzegopteryx: This forum needs some serious attention; I'll be at it for a moment, unless I get other tasks that do not allow me to do so.

Hatzegopteryx: It's a genetic fallacy. It's basically an argument that intends to discredit the opponent's position by asserting the opponent's failure to act consistently in accordance with that position.
