The gravigrades were the giant sloths, AFAIK. Gravis in latin means heavy,
and there's no doubt some giant sloths wer every much so!

As well, they woudl have to eat damn large amounts of insects, and could
easily wipe out a whole ant colony just for one meal! I don't think 
insects have ever been preyed upon by very large animals. It's just a too
inefficeint food source for large species.

As for there claws, they could have also been used for protection from
predators, or even inter=species mating-related fights.
