Year: 2009

[Benson et al. 2009]Definition

About
Megaraptora is a group of carnivorous theropod dinosaurs with long forelimbs and huge hand claws. The group was coined in 2009 by Benson and chums who assigned it as a sub-family to Neovenatoridae. Then it was held up as evidence that some members of Allosauroidea (to which Neovenatoridae belongs) lived right up to the latest Cretaceous and that tyrannosauroids didn't get all of their own way. However, in 2013 Novas recovered megaraptorans as tyrannosauroids. Not all paleontologists agree, though.

Etymology
Megaratora—Great plunderers—is derived from the Greek "megas" (great, large), and the Latin "raptor" (plunderer, thief) and "-a" (plural).
