Jobaria
Encyclopedia : J : JO : JOB : Jobaria
Jobaria was a sauropod dinosaur discovered in the Sahara Desert, and is one of the most completely known Cretaceous sauropods. It was named after "Jobar", a creature of local legends, and is thought to have been about 18 metres long. It lived in the Early Cretaceous (Aptian or Albian age).
Unusually for its late occurrence, Jobaria seems to be a very primitive sauropod. It has been interpreted either as a basal macronarian (Upchurch et al 2004), or as a non-neosauropod eusauropod, just prior to the Neosauropod clade.
