described as a species of Antarctosaurus
by Charles Alfred Matley and
Friedrich von Huene in 1933, a 1995 study of the remains saw
the material reclassified as its own genus, Jainosaurus.
is named after Indian palaeontologist Sohan Lal Jain who had
previously conducted a lot of study upon the fossils, however Jain
has since suggested that Jainosaurus may actually
be a specimen of
Titanosaurus. Despite this however Jainosaurus
is still usually
regarded as being a distinct genus.
Jainosaurus would have shared its habitats with other dinosaurs such as Isisaurus, Rajasaurus and Indosaurus.
