Museum of Western Colorado (MWC) 8028 is a recently-described specimen of the sauropod dinosaur Haplocanthosaurus, a rare taxon from the Upper Jurassic Morrison Formation of the American West (Foster and Wedel 2014). In most aspects of its morphology, MWC 8028 closely resembles previously-described specimens of Haplocanthosaurus. One exception is that the neural canals of the proximal caudal vertebrae are uniquely expanded, excavating both the centra and the neural arch pedicles (Figure 1). To investigate these unusual features, we scanned the fossils using computed tomography (CT), and generated and printed 3D models of the vertebrae and inferred soft tissues. Herein we describe our methods, and compare the expanded neural canals in MWC 8028 to similar features in other dinosaurs, including extant birds.
