The recently described titanosaurid, Futalognkosaurus dukei, has the most complete skeleton known (all cervical and dorsal vertebrae and hip bones) for a sauropod of its enormous size (estimated at around 34 m), and was recovered from Argentinian Coniacian Cretaceous deposits that also yielded a wealth of other contemporaneous plant and animal fossils (Calvo et al., 2007).
