Name:
Jiangjunosaurus
(Jiangjun lizard).
Phonetic: Je-ang-ju-no-sore-us.
Named By: C. Jia, C. A. Forster, X. Xu

Classification: Chordata, Reptilia, Dinosauria,
Ornithischia, Thyreophora, Stegosauria, Stegosauridae.
Species: J. junggarensis
(type).
Diet: Herbivore.
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.
Jiangjunosaurus
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
‘general’.
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.
