== Discovery and naming == thumb|left|Life restoration The Udelartitan fossil material was discovered in 2006 within sediments of the Guichón Formation (Araújo locality), near Quebracho in Paysandú Department, Uruguay. The holotype specimen, FC-DPV 3595, consists of the first three caudal vertebrae in approximate articulation. Additional bones representing an older individual (specimen FC-DPV 1900), including sixty caudal vertebrae, an incomplete left coracoid, the proximal and distal ends of the tibiae the proximal end of the fibula, six metatarsals, and two astragali, were also referred to Udelartitan. Many of the bones of the referred specimen were preliminarily described by Soto, Perea & Cambiaso in 2012, who also identified several purported osteoderms. However, Soto et al. (2024) found no evidence to support this assessment, arguing that they can more confidently be described as concretions.
