Turiasaurus, which translates to "Turia lizard," constitutes a genus of sauropod dinosaurs. This group is identified through a solitary fossil specimen, specifically the species Turiasaurus riodevensis, discovered within the Kimmeridgian-aged (Late Jurassic) Villar del Arzobispo Formation located in Teruel, Spain.

Turiasaurus carries the significance of 'Turia lizard,' although it's worth noting that 'Turia' is the Latinized rendition of Teruel, denoting the Province where the initial Turiasaurus fossils were unearthed. Intriguingly, Turiasaurus has taken on the role of the type genus within the Turiasaria group (hence the resemblant nomenclature), encompassing other genera like Losillasaurus, Galveosaurus, and Zby. This deviation from the norm is somewhat unusual, considering that typically the first designated genus establishes the group name. In this scenario, that distinction would belong to Losillasaurus, which was formally designated in 2001.

Turiasaurus is thought to be the largest dinosaur ever uncovered in Europe and ranks among the titans of the dinosaur world. Initial estimations projected its length at over 30 meters (98 ft), potentially reaching 36–39 meters (118–128 ft), and weighing about 40–48 tons (44–53 short tons). However, more recent evaluations propose a length spanning 21–30 meters (69–98 ft) while maintaining a similar weight range of 30–50 tons (33–55 short tons). Despite its impressive dimensions, the skull's length measures 70 centimeters, which is relatively modest. It was estimated that a larger head would have caused the neck to break.
