Primeiro registro de ossos pós-cranianos de Titanosauria (Sauropoda) no município de Alfredo Marcondes (estado de São Paulo), formação adamantina (Turoniano-Santoniano), Bacia Bauru

Sauropod dinosaurs (Titanosauria) remains were collected in Upper Cretaceous sandstones, at Alfredo Marcondes site, Adamantina Formation, Sao Paulo state. These fossils comprise a fragmentary right femur and a proximal portion of a right tibia. The femur was assigned to the family Titanosauridae on the basis of the following features: straight shape, somewhat anteroposteriorly flattened; fourth trochanter slightly medially pronounced right above of the middle part of the bone's lenght; a proximolateral proeminence of the greater trochanter and a medial deflection of the proximal end of the femur. The tibia described here shares similar features with Titanosauria taxa like a well developed cnemial crest only slightly curved laterally; a deep longitudinal concavity separating the crest from the tibial shaft and a very anteroposteriorly expanded proximal end. These are the first fossil bones of dinosaurs recovered from Alfredo Marcondes municipality.
