In 1922, Carl Wiman, head of the then Palaeontological Institute at Uppsala University, received a series of crates containing dinosaur remains from the Upper Cretaceous (upper Campanian–Maastrichtian) Kirtland Formation of New Mexico, U.S.A. The specimens had been collected in 1921 by the famous American fossil hunter, Charles H. Sternberg, during a commissioned 5 month field expedition to the in the San Juan Basin. Arguably, one of the most significant specimens recovered was the partial skull of the spectacular crested hadrosaur Parasaurolophus tubicen. The holotype (PMU 24925) comprises the massive crest and neurocranium, together with parts of the pareital, frontal, prefrontals, postorbitals, squamosals and exoccipitals. The right quadrate is also preserved in articulation with the quadratojugal and pterygoid; the right jugal, maxilla, pterygoid, ectopterygoid and the anterior section of the lacrimal make up the facial region of the skull. Wiman was the first to propose that the crest of Parasaurolophus functioned as a vocalization structure. This study aims to investigate the functional morphology of the crest in this hadrosaur, in conjunction with endocranial anatomy, using CT-scanning and 3D modelling of the intracranial chambers. Comparisons with other specimens of Parasaurolophus will permit reconstruction of sensory capabilities in this 'classic' dinosaur taxon.
