Rinconsaurus

Rinconsaurus is a genus of titanosaur sauropod dinosaur from the Late Cretaceous in what is now Argentina. The type species, Rinconsaurus caudamirus, was described by Calvo and Riga in 2003, and is based on three partial skeletons.

==Description== Like all sauropods, Rinconsaurus was a large long-necked quadrupedal animal, with a long, whip-like tail and four pillar-like legs. Rinconsaurus was an unusually slender sauropod. Although fossil discoveries are incomplete, and no complete necks or heads have been found, fully grown Rinconsaurus are estimated to have been 11 meters (36 ft) long and approximately 2.5 meters (8 ft) high at the shoulder. The body mass of Rinconsaurus has been estimated to be between 3.21 and 5.39 tonnes.
