Named By: Z. Dong - 1990.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Sauropodomorpha, Sauropoda, Mamenchisauridae.
Species: B. sui (type).
Size: Around 4.8 to 5 meters long for the remains found, though older individuals would have likely been larger.
Known locations: China - Shishougou Formation.
Time period: Callovian of the Jurassic.
Fossil representation: At least 17 individuals represented by partial remains, probably of juveniles.
creation of the Bellusaurus was born out of the
discovery of a bonebed
of at least seventeen individuals. Features on some of these fossil
such as the lack of fusion on some parts means that these individuals
are probably juveniles and therefore not fully grown. It has also led
to speculation that Bellusaurus may actually be the
juvenile form of
the previously named but not yet well understood genus.
Other sauropods known from the same formation as Bellusaurus include Mamenchisaurus, Klamelisaurus and Tienshanosaurus. Predatory threats to Bellusaurus include Monolophosaurus, the tyrannosaur Guanlong and the allosaurid Sinraptor. Other creatures that Bellusaurus may have come into contact with include the stegosaur Jiangjunosaurus, the basal ceratopsian yinlong and the pterosaur Sericipterus.
