Peter Rose examined "Pleurocoelus" fossils from Jones Ranch and found that they actually belong to a new basal titanosaurifom of the lower Cretaceous, differing from previously described Pleurocoelus "in the shape of the caudoventral margin of the maxilla, the shape of the distal scapular blade, and the shape of the proximal condyle of the tibia"(Rose 2007). Rose named the new sauropod Paluxysaurus Jonesi.
