Classification: Chordata, Reptilia, Dinosauria, Ornithischia, Thyreophora, Stegosauria, Stegosauridae.
Species: J. junggarensis (type).
Size: Uncertain, due to lack of remains, but in the past has been roughly estimated to be around the 6 meters mark.
Known locations: China, Xinjiang - Shishugou Formation.
Time period: Oxfordian of the Jurassic.
Fossil representation: Partial skull and lower jaws, as well as partial post cranial skeletal remains including scapula, coracoid, ribs, eleven cervical (neck) vertebrae and two plates from the neck area. Holotype fossils are of a subadult individual.
is a genus of stegosaurid
dinosaur that lived in China during the
earlier part of late Jurassic. Though Jiangjunosaurus
is far from
complete, this stegosaur is known to have had a skull that was
elongated in proportion to its width. Jiangjunosaurus
was found by
itself, and because generals are buried in temples by themselves,
the name Jiangjunosaurus was chosen as
‘Jiangjun’ is Chinese for
Other dinosaurs that are known from the same fossil bearing formation as Jiangjunosaurus include the primitive ceratopsian dinosaur Yinlong, and sauropods such as Mamenchisaurus, Bellusaurus and Tienshanosaurus. Numerous small theropod dinosaurs such as Guanlong, Zuolong and Aorun may have also lived in the same habitat as Jiangjunosaurus, but particular predatory threats to Jiangjunosaurus likely include the larger Monolophosaurus and Sinraptor. In the skies above Jiangjunosaurus, pterosaurs such as Sericipterus flew.
