In 2012, numerous other sauropod remains that had been known for decades under various different names were also classified in the genus "Sauroposeidon". Sauropod bones and trackways had long been known from the Paluxy River area of Texas, usually referred to the genus "Pleurocoelus", including partial skeletons (particularly from the Glen Rose Formation, above the Twin Mountains Formation). In the mid 1980s, students from the University of Texas at Austin discovered a bonebed on a ranch in Hood County, but early work stopped in 1987. The quarry was reopened in 1993 and was subsequently worked by parties from Southern Methodist University, the Fort Worth Museum of Science and History, and Tarleton State University. All sauropod remains from this bonebed appear to come from the same genus of sauropod. Petrified logs are also known from the site. The site was fluvial when its rocks were being deposited, with channel sands and muds, and concretions of calcite-cemented sandstone containing fossils. Following excavation and preparation of the majority of the fossils from the site, its sauropod species was given the name "Paluxysaurus jonesi".
