Page 51 - Everything You Know About Dinosaurs is Wrong

The best way to answer this is to look at modern-day dinosaurs as lots of modern raptors still have sickle-shaped claws on their feet – we call these talons.
None of these animals use their claws to slash or cut open their prey. Instead, they use their claws to hold on to their prey – usually pinning them to the floor and standing on top of them!
Some palaeontologists have even built models of dromaeosaur feet and experimented to see whether they were any good at slicing through things and, it turns out, they’re not very good at all!
There were many other types of strange dinosaur feet:
Animals that move swiftly often have very light limbs and evolve simpler feet through time.
The very recently discovered VESPERSAURUS ran around its desert home on just one toe – like horses do today.
Although dinosaurs with sickle-shaped claws probably didn’t slash their prey with them, they would have been useful tools that could have been used for many tasks. Remember, it’s difficult to describe the behaviour of an animal just from one part of its body and it’s important not to get too carried away with guesses when you only have a little information!
BALAUR was one of the oddest of the sickle-claw-sporting dinosaurs . . . it had TWO sickle claws on each foot!
Some dinosaurs, like CENTROSAURUS, walked on claws that had actually evolved into hooves! The enormous sauropods still walked on their tiptoes, but the rest of each foot was supported by a large, fleshy, fatty pad – just like elephants today (yes, elephants walk on their toes)!
