Velociraptor Bad At Disemboweling
illtron writes "British scientists at the University of Manchester were apparently bored and decided to find out, once and for all, if the Velociraptor was as mean as Jurassic Park would like everyone to think. They created a robotic Velociraptor leg to simulate the effect that leg would have on pig and crocodile skin. It turns out that disemboweling a dino probably would have been out of the question, since the best that big claw could do was usually just to leave a deep puncture." From the article: "I realized that the sick-claw was not a knife, but was rather more like the claw of a cat. Cats use their claws to pierce and hold prey, not to disembowel. Whereas my work was mostly theoretical, Phil took one step farther as he was given the opportunity to mechanically test the disemboweling hypothesis. His work is very important,"
I recall a long time ago seeing one of those "animals attack" shows and it showed some sort of big cat attacking a much larger prey by running alongside it and pouncing on its belly from underneath and using its legs in a manner similar to what is described above. That sucker was disemboweled, that's for sure.
If you saw away at a large chunk of meat with a small but sharp knife you can make a deep wound.
Try "sawing away" at something, anything, with an awl. The whole point here is that a velociraptor claw is not a sharp knife, but a pointy stick.
You can make a wound as deep as the "hilt", but no "longer" than the diameter of the claw.

He's obviously never had a catnipped-up cat grab a hold of his forearm with the front claws and use it's back legs to scrape the everlovincrap out of him.
Everyone knows a cat's claw is Piercing+1, Slashing-5 sheesh
Seriously though. Look at the cat scratch, it's not a clean cut, it's similar to if you got scratched by a pointy stick, not a razor. If the claw went deeper it wouldn't move because only the point is sharp, not the edge.
Jurrasic Park misrepresented the Velociraptors.
Velociraptor has a skull length of 249 mm (9.80 in), a total length of 2.7 m (8 ft 10 in), a hip height of 0.5 m (1 ft 8 in), and weighs 20 kg (45 lb). The 'raptors portrayed there were modelled after a larger relative, Deinonychus.

The point of the robot arm is to get the same range of motion as the actual Dinosaur would have had. They can then give each joint a strength proportional to the size of the muscle that would have been attached to it (some guess work here I would assume). Then they can play around with it and see what different movements and would kind of attacks would have been possible and how much damage they would do. Animals use their claws in different ways, and the appendage the claw is attached to gives you just as much information as the size and shape of the claw itself. The expirement isn't what damage can WE do with a velociraptor claw it's what damage the velociraptor could have done.
