Rinconsaurus Test 2
''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. Discovery and species Fossils of ''Rinconsaurus'' were discovered in 1997 by Gabriel Benítezin strata belonging to the Bajo de la Carpa Formation near Rincón de los Sauces, in the Neuquen province of Argentina. ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the more recent of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Aus ...
