Skip to 4:18 for the crunching part.

I guess we can now reasonably say that tooth puncture marks are not the best basis for bite force estimates.
P.S. I am not sure if this belongs here or in my bite force thread.

If dromaeosaurs could flex their pes like this→ and if they could generate a lot of force with them like eagles, no need for an alligator-like bite force on a weak skull. |

Whether it could or could not flex its metatarsals like that does not mean that it actually used it for actually grabbing things like birds of prey due today. It is all about how it moved around; birds of prey hunt by striking from the air (and lack gripping ability in their arms completely), so naturally feet that are designed for clamping small animals like rabbits and rodents would be ideal for that sort of lifestyle. For terrestrial-based theropods such as deinonychus, catching even small prey with toe enclosure would be inefficient, as the creature would have already been able to use its jaws to catch small things.
The redundancy of the limbs and claws only becomes much greater as theropod jaw strength and size intensifies, as in many large-jawed theropods that is their primary hunting tool in general. Even though dromeosaurids were probably not as reliant on jaw usage as many larger macrophagous groups, the function of their hind legs for grabbing (grabbing and grappling are two different things) would still be ineffective.

Although dromeosaurid skulls were definitely not the strongest or the most powerful, they still lack the capabilities that allow birds like eagles and hawks to be effective talon-based hunters.

I think someone should attempt to replicate the results of the dromaeosaur bite force study that used the tooth marks. And maybe include a detailed comparison of the respective material properties if this wasn’t already done.
