Embryonic Skulls of Titanosaur Sauropod Dinosaurs
Luis M. Chiappe, Leonardo Salgado, Rodolfo A. Coria
Little is known about the cranial anatomy of the
taxonomically diverse and geographically widespread
titanosaurs, a paucity that has hindered inferences about
the genealogical history and evolutionary development of
the latest sauropod dinosaurs. Newly discovered fossil
eggs containing embryonic remains from the Late Cretaceous
of Argentina provide the first articulated skulls of
titanosaur dinosaurs. The nearly complete fetal skulls
shed light on the evolution of some of the most notable
cranial features of sauropod dinosaurs, including the
retraction of the external nares, the forward rotation of
the braincase, and the abbreviation of the infraorbital
region.
