And when John x-rays the ridge the incredible truth is revealed. Until very recently, there was absolutely no scientific proof that they had anything to do with each other at all. So Velociraptor looked like a bird - had teeth - and by making use of its feathers, and its long tail, this dinosaur was super agile as well as fast. The leg is a beautiful piece of craftsmanship but can it pull a punch? It didn't only do it once but it did it twice which suggests that the animal had struck something really hard in both directions. It's not going toss it around think about well maybe I should've attacked it.
In prehistoric times dinosaurs were engaged in a constant battle for survival. Eight times more powerful than a lion. But John has noticed something else. These would have been like razor blades as the animal buried its face into its prey using its body weight, hanging back on these hook-like teeth ripping through flesh. Here in this hanger they normally in crash test cars. Working together, the turkey-sized Velociraptors would have had a much better chance of bringing down one, rather sturdy, Protoceratops.
I think lets see what happens when we shove that thing into it at speed Cutting through skin appears to be no problem, but in life, skin is attached to fat and muscles so the team decide to use a more realistic challenger in the form of a pork belly. The first is a re-enactment of the fighting dinosaurs scene, while the second pits it against two Velociraptors, which the latter wins. This is the femur up here is that right. There are only three fossil skeletons of Triceratops for scientists to work on and none of these are complete. One theory has it that this turkey-sized predator was hunting in groups.
So, putting together the most accurate evidence, taken from the very latest research - meet Tyrannosaurus rex. Kent could see that Triceratops was just the same. This is what it did to a piece of pork. So to consider how fast a tyrannosaurus could run, we may have to use something other than footprints. T rex has a pivot in the middle with a considerable amount of weight spread out on either side. Ankylosaur armour was so similar to crocodile armour that scientists reckon its fair to assume that baby Ankyosaurs would have been just as vulnerable as baby crocodiles are.
Two things wrong with the experiment: both of the participants. They'll discover who killed who, 75 million years ago. Back in London the special effects team sets about building a replica aluminium tail. Can you get it cranked up to full speed? First a fossil of a damaged horn. Lets have a look Just look at that.
And it also had a disproportionately long tail. Also I was under the impression that Akylosaurus was a North American dinosaur, not mongolian. In this case we see that the brain size, which would be right in this region, is almost the same size as the spinal cord region. But the feathery arms would have acted like a birds wing. The one thing it might have been able to do is change it's posture when it was running. Ken has flown to London to witness the experiment. In fact if one looks all over this specimen you'll find over 80 of these punctures and cut marks.
It seems certain that this iconic dinosaur was huge, and fearsome. What that tells us is as sensory information came into the brain it basically went straight through. At eight tons, this would have been some heavyweight for T rex to take on. I think we have got to test this further This is quite a feeble test It is a feeble test. But however futuristic the research techniques, all investigations begin with the ancient fossil bones.
But there is something strange about this line. . But it also had blind spots. Even a fully grown Tyrannosaurus is no match for a healthy, alert Triceratops in a head on fight. Of what use is the information that a T. Look at that thing, oh my god.
This would have been a devastating weapon. And scientists know exactly how successful it was because countless numbers of Velociraptor teeth have been found among the fossilized remains of its victims. We're very fortunate with this, something that we've never seen before is the damage that occurred on this tail club where the bone had broken off and that could only have happened if the tail club had hit something really hard. Bond movies, shark movies, they've done them all! Instead it tends to rot. For the biomechanical test, Ken has provided an oven-ready version as a stand-in. We're close to release, everyone ready? The exact replica of the claw, made out of resin, has a very sharp point, but the underside isn't sharp at all. There's a really deep puncture mark right here.
Because it was so thin and shaped like a scythe it immediately made people think about a slicing action or a cutting action and led to the idea that this was used to disembowel prey. It seems that Velociraptor wasn't capable of disembowelling its victims. Its hooked right in Absolutely this is definitely not for disembowelling, this claw The end of the claw was obviously sharp enough to pierce the flesh, but it couldn't cut through the flesh because the underside is round and completely blunt. For instance, If you look here there are some gouges along the top. But how did kill its victim? This is the tail club, this is the business end of an ankylosaur.
