[1] After the discovery of a new quarry from the Shaximiao Formation in 2016, the holotype of Yuzhoulong, CLGRP V00013, was discovered in Pu'an town in Yunyang County in Chongqing.

It was named as a distinct genus and species by Dai et al. in 2022.

It was partially buried in the rock at the time of its description, mixed in with the fossils of another, unnamed sauropod.

[1] In 2022, Dai et al. added Yuzhoulong to a number of different phylogenetic analyses, which consistently recovered as it a basal macronarian.

This proves that macronarians existed by at least the Middle Jurassic, indicating a higher diversity of neosauropods in this age.
