The Weirdest Dinosaur That No One Notice.

I've heard of this thing somewhere. I know palaeontologists had an explanation of what it did with those arms, but I'm not sure at the moment.

I saw it in the book and do noticed the small arms and they have 1 claw on each claw. But they can be useful for defending itself.

Those arms were probably used as hooks, helping the dinosaur catching the ants and termits out of their nest, as diet. Most dinosaurs of this clade, had only one finger, but there are some cases where some species had two: a small, almost unnoticeable one, and the other hook-clawed.

Most likely for slashing, Run up below its prey, slash open the belly "Maybe here, or here, across the belly, spilling out your intestiens, the point is, your alive, when they begin to eat you..." - Alan Grant

It would seem logical, If sloths could move faster they'd slash their prey (scary as hell) But It would have to travel in packs maybe...
