allosaurus hatchet bite strength

I'd hazard to guess 4 tons tops. Allosaurs don't have very high bite forces to begone with.

I think it was 4-5 tons allosaurs had very low bite forces in general

I'd say 2-4 tons.

wow so low. i would gess 4 to 6 tons.

and what about saurophaganax or erectopus.

Sauro probably had about 5 tons, give of take, and Erectopus was probably half a ton give or take. 

thats petty strong for an animal 10 feet long and 400 pounds.

Honestly, the only reason rayfield proposed the hatchet jaw was because allosaurus had a normally weak bite.

Allosaurus skull morphology hints at a larger gape and large attachments for neck muscles that were first interpreted as evidence of the 'hatchet bite'.

Well, in 2003 that was reinterpreted as more of a "slash and tear" killing technique, where allosaurus targeted convex surfaced on large prey animals(i.e. sauropods). Bite force was sacrificed for reinforced neck muscles, which helped dig the Allosaurs teeth deeper into its preys flesh.

Interesting Carno, did not know that. Learn something new every day. 

Carnosaur, how strong do you assume the axe bite to be.

I personally estimate it's hatchet bite at around 2-3 tons psi. Their skulls were very weak, so I don't see how they could produce a higher force...

There skulls are not weak

Relatively, yes they are. They are not very well designed to withstand high amounts of presure. Just watch Planet Dinosaur. It explains it well.

It also states that it could witstand high amounts if force when it does a hatchet bite. And I love planet dinosaur.

The point is, they didn't have strong skulls. Whether you call it weak is up to you I guess.

I guess so
