[D] Jainosaurus septentrionalis [sG] [T]
Hunt, Lockley, Lucas & Meyer, 1995
Cretaceous Late, Maastrichtian
Saurischia Sauropodomorpha Sauropoda Titanosauria
Lameta Formation, Madhya, Pradesh, India
Jainosaurus septentrionalis (Hunt, Lockley, Lucas & Meyer, 1995) > Antarctosaurus septentrionalis (Huene & Matley, 1933)
Jainosaurus can be distinguished Isisaurus by the orientation of the occipital condyle relative to the occiput, the shape of the basal tubera, differences in shape of the scapula and proximal humerus, and the robustness of the ulnar shaft. (Wilson et al. 2009)
Described by Huene & Matley in 1933 as Antarctosaurus septentrionalis, it was redesignated in 1995 by Hunt, Lockley, Lucas and Meyer.
New species Titanosaurus colberti described in the genus Titanosaurus Lydekker, 1877, based on partial skeleton, made a junior synonym of Titanosaurus indicus because it seems to be based on material of a large individual of the latter species; most material previously referred to Titanosaurus blanfordi placed into Titanosaurus madagascariensis.
Diagnosis of genus (as for the type species)
Caudal vertebrae procoelous, laterally compressed with high centrum; tow cranial hemophosial facets large, widely apart from each other; caudals very similar to Titanosaurus indicus, both having flat sides, the latter having more pointed cup. (Mohabey, 2001)
