A Basal Lithostrotian Titanosaur (Dinosauria: Sauropoda) with a Complete Skull: Implications for the Evolution and Paleobiology of Titanosauria
A number of distinctive morphologies—such as the ossified cervical tendon, extremely pneumatized cervical vertebrae, and a habitually downward-facing snout—that have rarely, if ever, been documented in other titanosaurs are documented, thus broadening the understanding of the anatomical diversity of this remarkable sauropod clade.
A reappraisal of Notohypshilophodon comodorensis (Ornithischia: Ornithopoda) from the Late Cretaceous of Patagonia, Argentina.
A restudy of Notohypsilophodon is presented, which increases the knowledge of the evolutionary dynamics of South American Cretaceous ornithopods, and broadens theknowledge of the early Late Cret Jurassic continental vertebrate assemblages of central Patagonia and of the Southern Hemisphere in general.

The formation of this structure appears to have been a non-pathological metaplastic ossification, possibly induced by the continuous tensile forces applied to the element.
