A pair of Megaraptors were just about to start feeding on their freshly killed prey, when a giant Giganotosaurus appears on the scene, not leaving the chance for a free meal.
The Megaraptors try to compensate their size with aggression, however this is just bluf: they know they don't stand a chance against this giant enemy: the Giganotosaurus is a giant with his 13 metres in length compared to the pair of 8 metres long Megaraptors. The two hiss, roar, feint and one of them even slices with his giant claws through the belly of it's prey, trying to make the Giganotosaurus believe they are stronger.
It's all about attitude, like today's wolverines do when they face a grizzly bear and this actually works: the bears flee for an animal the size of a big badger.

Both Theropods lived in what is now concidered Argentina during the Late Cretaceous Period.
Giganotosaurus was about 13 metres long and about the size of T-rex. These giant meat-eaters had razorlike teeth for cutting through flesh, not crushing bone. They were able to hunt in packs and killing Argentinosaurus, one of the biggest Sauropods.

Megaraptor is a different story: few is known about this carnivore. The only fossil we have is a giant 30 cm long claw which was first believed to be the footh claw of a giant raptor (that's why he has this name) but later a complete arm was found, showing that the claw was attached on the first finger. We don't know what kind of theropod he was, an Allosaurid, a Carcharodontosaurid, a Spinosaurid or something else? This leaves some space open for imagination so I made him look like an Allosaurid.
