Discovery and speciesEdit
The first and to date only fossils, albeit postcranial (missing the skull), were recovered in 1985 during the construction of a gas facility, which explains the dinosaur's unusual name. The fossils were defined as the type species Gasosaurus constructus by the paleontologists Dong Zhiming and Tang Zilu. There have still been very few fossils retrieved, so exact details are unknown. Specifically, no skull has been found. Some paleontologists have speculated that Gasosaurus and Kaijiangosaurus may be one and the same species. Traditionally thought to be a megalosauroid, Holtz (2000) found it to be a basal coelurosaurian, although later Holtz et al. (2004) suggested it was a basal carnosaur (possibly a sinraptorid) on the basis of data from undescribed specimens. It may in fact be the most basal coelurosaurian yet known, or may even be close to the common ancestor of the two groups; in any case, it represents one of the oldest definitive tetanuran theropods.
2014 egg hatch hoaxEdit
In early 2014 a series of viral online news posts circulated that a 200 million year old Gasosaurus egg had hatched in the Museum für Naturkunde ( Museum of Natural History) in Berlin,Germany, following an online spoof article from the tabloid World News Daily Report.
