Gigantoraptor erlianensis (2007)

Digital painting

The recently described largest known member of the oviraptorids, Gigantoraptor erlianensis, from Mongolia, is shown to scale with a more conservatively sized member of this group, Oviraptor philoceratops, the latter brooding a clutch of eggs. Although Xu et al. (2007) (Nature 447:844-847), on whose skeletal reconstruction the image is based, did not find direct evidence of feathers associated with the fossils of Gigantoraptor, other members of the group demonstrate such integumentary structures, and Gigantoraptor is oddly more birdlike in its anatomy than its smaller relatives.
