Tyrant king
MemberCompsognathusAug-28-2014 5:45 AMthis was briught up several times in orher topics and i want it setteld for good.I mean how strong in pounds . Don't give me that big load of BS that a lion or even a freakin leopard has a stronger bite then allosaurs. I k ow allosaurus have weak bites in general but they actually have quite strong skulls. They didn't even need a strong bite because of there dentition(aka teeth). My estimate it has a bite at about a ton in force. And this is for a. Fragilis. I know that just about every study done on its bite says its super weak but I dusagree. What are your thoughts on the bite force of allosaurus.
what are your opinions on charcaradontosaurids such as giganotosaurs. Since they are apperantyl bulkier then allosaurids. So I think they had even stronger bites. in my opinion about 2 to 4 tons. But the bulKirsten charcaradontosauridas such as tyrranotitan and acroanthosaurs would have a bite of 3 to 4.5 tons. Not as strong as t.rex but certainly not weak or anything to be laughed at. Plus the fact that when it bite it would take huge chunks of flesh out and causing massive shock and blood loss. So what are your opinions on the bite forces air carcharaodontosaurids. And the bulkier ones like actocantosaurus?

MemberCompsognathusAug-28-2014 7:00 AMWell there was that theory in Planet Dinosaur it used it's Head/upper jaw as an axe...so it didn't require a huge a bite force...
From what I heard (just heard), it had a bite force of 300-500...personally I'd say allo must've bit at least 1,000-2,500 lbs per square inch...however Im not a scientist and don't have the skulls to test it...
But lets see what the others say...

MemberCompsognathusAug-28-2014 10:24 AMAlrighty, i'll just reiterate what i've said on other posts seeing how we have an official thread now.
The "Bite being weaker then a lions" was a media invention
In that study (Rayfield 2001) Lions weren't even features as the test subjects in it. The scientific name, Panthera Leo doesn't even get mentioned once.
However, the Tiger is mentioned( Panthera Tigris) and has an astonishingly high bite force of ~910 kg(2,006 lbs/ 1 ton)
Now, let's get real in depth with the skull and jaw mechanics of Allosaurus Fragilis, shall we?
In short order, this theropod didn't have a very high bite force. Why?
Here we see it in a muscle study with the likes of Tyrannosaurus and Ceratosaurus.
A cursory glance reveals the jaw muscles (C. Mandibularis) are relatively low in comparison with the other theropods. And indeed, where muscle would anchor in the jaw and on the lower jaw is relatively sparce for such a large theropod.
But, did Allosaurus really need a high bite force? Or a hatchet jaw function?
In The muscle powered bite of Allosaurus(2003) The idea of the hatchet jaw was discussed with great fervor, and was ultimately discredited. You can read more when i link the paper in, skip to the section "Further problems withe the hatcheting interpretation" But, a new theory took it's place; Allosaurus would bite into its hapless prey, and shake its head back and forth violently. See, it's teeth are very blade like and are covered with dozens of serrations. When An Allosaurus would shake its head, the teeth would dig deeper into the flesh, causing major damage and perhaps severing arteries. Modern day great white sharks utilize this technique as well. This has been my woring hypothesis for years now, and it's pretty cool to see it in a scientific paper, haha.
To conclude, Allosaurus didn't need a high bite force, or a hatchet jaw, because it would have utilized a killing technique that is arguably just as lethal as the bone crushing dentition of the Tyrannosaurs.

Regarding Giganotosaurus, it was established it had a bite force of three or so tons. Carcharodontosaurus, being closely related, would have a bite that would match that or be some what more.

MemberCompsognathusAug-28-2014 10:43 AMCarno, hit the Allosaurus stuff right on the nose so I'm not gong to bother explaining Allosaurus.
But, as for the Carcharadontosaurids, Giganotosaurus bite hasn't really been tested a scientist did estimate it at 3-4 tons but, it hasn't really been tested. I usually put it at 6800 psi (3.5 tons) as for Carcharadontosaurus. It probably had a bite force slightly less as it seems overal more slnder then Giganotosaurus.
