Beibeilong is an extinct genus of oviraptorosaurian dinosaur. The genus contains a single species B. sinensis, named in 2017 by Pu and colleagues based on a nest with a possible embryo (nicknamed "Baby Louie") and eggs that were discovered in the Henan province in 1993. It was similar to but more basal than Gigantoraptor, and may have been of similar size as an adult. This result was consistently recovered by phylogenetic analyses incorporating ontogenetically variable characteristics, which led Pu et al. to conclude that they were distinct taxa.[1]
