This family of dromaeosaurs evolved rather recently from the normal dromaeosaurs during the Miocene. Like normal dromaeosaurs, gigaraptors hunt in packs, have great intelligence and have sickle claws on their hands. The main differences between gigaraptors and their normal dromaeosaur ancestors is that gigaraptors also have sickle claws on their hands similar to a megaraptoran and grow to the size of medium sized tyrannosaurs. The gigaraptors diversified very rapidly during the Pliocene and Pleistocene. They outcompeted the carnosaurs and African tyrannosaurs into extinction. However, 1,000 years later, Giga-Raptors started to move South to prevent their species of going extinct.
Giga-Raptors (Subfamily: Gigaraptorinae)Edit
Giga-raptors get their name because they are the largest dromeaosaurs, around the size of an Argentinosaurus. Despite this, they are very social dinosaurs and they hunt in packs. By hunting in packs, giga-raptors can take down many different kinds of large prey, ranging from sauropods to therizinosaurs. If larger prey is scarce, they'll also hunt smaller ornithopods and ornithomimids.
