Barapasaurus comes from the lower part of the Kota Formation, which is of Early to Middle Jurassic age.

Barapasaurus is known from approximately 300 bones from at least six individuals, so that the skeleton is almost completely known except for the anterior cervical vertebrae and the skull.

[1] The specific name tagorei means 'Tagore's', which honours Bengali poet, writer, painter, and musician Rabindranath Tagore.

The age has generally been interpreted as Early Jurassic, with the Lower Kota Formation in particular dating to the Sinemurian to Pliensbachian, roughly 184–200 million years ago.

[4][5] The approximately 300 bones were found together with large trunks of trees scattered over an area of 276 square meters.

[2] Bandyopadhyay and colleagues (2002, 2010) interpret this assemblage as a herd that died due to a catastrophic event, likely a flood.

[2] Jingshanosaurus Antetonitrus Chinshakiangosaurus Kotasaurus Barapasaurus Vulcanodon Shunosaurus Camarasaurus Omeisaurus The relationships of this genus within the Sauropoda are debated.

Other vertebrates of this part include another early sauropod, Kotasaurus, as well as the mammals Kotatherium, Indotherium and Indozostrodon.

The upper part of the Kota Formation additionally contained a pterosaur (Campylognathoides), a turtle, two rhynchocephalians, a lepidosaur and some mammals.
