Rauhut, O. W. M., K. Remes, R. Fechner, G. Cladera, and P. Puerta. 2005. Discovery of a short-necked sauropod dinosaur from the Late Jurassic period of Patagonia. 435:670-672.

A new dicraeosaurid, Brachytrachelopan mesai, (from the Greek for short-necked, and Pan, in honor of Daniel Mesa, the Patagonian shepard who found the specimen while searching for some sheep, is described from the Tithonian-aged Cañadón Cálcareo Formation of Patagonia, Argentina. The whole animal only measured about 10 m in estimated length, and it is pretty apparently an adult. Unfortunately, the specimen is mostly just axial material--nearly all of the limb elements were eroded away.
