Turiasauria was originally erected by Royo-Torres et al. (
2006) to include Turiasaurus, Galveosaurus and Losillasaurus, all of which hail from the Villar del Arzobispo Formation (Tithonian-Berriasian) of Spain.
Turiasuria was defined by the authors as "all Eusauropoda closer to Turiasaurus riodevensis than to Saltasaurus loricatus".
Cladistic analysis (Royo-Torres et al.,
2006; 1927) of 309 characters and 33 taxa suggests that the turiasaurians lie outside the Neosauropoda and form a monophyletic group.
The clade is diagnosed by the presence of vertical neural spines, posterior centroparapohyseal laminae on the dorsal vertebrae, the absence of pre- and postspinal laminae on the dorsal vertebrae, the absence of a scapular acromial crest, the presence of a prominent humeral deltopectoral crest, medial deflection of the proximal end of the humerus, and a distinct vertical ridge on the caudal side of the distal half of the ulna.
