English: Life restoration of the gigantic Late Cretaceous caenagnathid Beibeilong sinensis. The large-sized eggs and embryonic specimen (Baby Louie) assigned to this taxon indicate a notorious adult size comparable to Gigantoraptor.^[1] The robust body proportions depicted in this restoration are mostly based on Gigantoraptor and also Baby Louie (especially hindlimbs), based on the reasoning that some oviraptorosaurs retained limb proportions in their ontogeny.^[2] Since the both taxa feature similar hindlimb ratios despite their age, it is possible to use the more mature Gigantoraptor for other body regions as a primary reference.^[3]
