The cerebral region of the brain is separated from the rest of the brain by a distinct compression caused in the endocranial cavity. The rearmost part of the cerebral region of the braincase has a top with a small expansion. This is different from "Jainosaurus". However, relatively much larger expansions are known in the diplodocoid sauropods "Dicraeosaurus" and "Diplodocus". In MCCM-HUE-8741, the small opening in the skull roof middle is responsible for a swelling on the endocast that is suggestive of a pineal system. It is in the exact position where the pineal gland is expected to have been, between the forebrain and the midbrain.
