Rinconsauria („Ještěři z Rincón de los Sauces“) byl klad sauropodních dinosaurů ze skupiny Lithostrotia (vývojově vyspělých titanosaurních sauropodů), kteří žili v období svrchní křídy (geologický stupeň coniac až maastricht), asi před 89 až 70 miliony let.

Klasifikace

V současnosti řadíme do tohoto kladu pouze čtyři rody sauropodních dinosaurů, a to rody Rinconsaurus, Muyelensaurus, Punatitan a Bravasaurus. Tyto rody spadají do kladu Colossosauria.[1] Klad byl formálně stanoven v roce 2007.[2]

A restoration of Rinconsaurus compared to a human ,

• Based proportionally on fossil elements and skeletal reconstruction featured in the Rinconsaurus description,[1] with missing parts based on other titanosaur reconstructions. The remains of Rinconsaurus represent two adults and a juvenile all of which are incomplete; some of the proportions shown here, such as the neck, limb lengths, and skull shape are not certain.
• Osteroderms are not yet known in Rinconsaurus. The osteoderms shown here are based loosely on Mendozasaurus.[2] Osteoderms are known from at least 10 titanosaur genera spread across the family tree but it's not clear if all titanosaurs had them.[3] Titanosaur osteoderms are rare and their layout and position on the body are not certain. [4]
• The colours and patterns, as with the majority of reconstructions of prehistoric creatures, are speculative.
• Human silhouette approximately 180 cm tall.
