Vertebral Pneumaticity in the Ornithomimosaur Archaeornithomimus (Dinosauria: Theropoda) Revealed by Computed Tomography Imaging and Reappraisal of Axial Pneumaticity in Ornithomimosauria

Abstract: Among extant vertebrates, pneumatization of postcranial bones is unique to birds, with few known exceptions in other groups. Through reduction in bone mass, this feature is thought to benefit flight capacity in modern birds, but its prevalence in non-avian dinosaurs of variable sizes has generated competing hypotheses on the initial adaptive significance of postcranial pneumaticity. To better understand the evolutionary history of postcranial pneumaticity, studies have surveyed its distribution among non-avian… Show more

“…However, postcranial pneumaticity is not unique to birds, being observed in non‐avian dinosaurs (Britt, 1993; Wedel, 2003; O´Connor, 2006, 2007; O’Connor and Claessens, 2006; Sereno et al ., 2008; Makovicky and Zanno, 2011; Benson et al ., 2012; Xu et al ., 2014; Watanabe et al ., 2015; Lambertz et al ., 2018) as well as pterosaurs (Britt, 1993; Butler et al ., 2009; Claessens et al ., 2009; Martin and Palmer, 2014). The presence of this condition in non‐volant taxa indicates that the interaction between postcranial pneumaticity and flight capability was secondarily acquired and suggests that the main function of postcranial pneumatization is not flight.…”

“…Several authors have analyzed the evolution of postcranial pneumaticity towards the avian line (Wedel, 2003; O´Connor, 2006; O’Connor and Claessens, 2006; Benson et al ., 2010; Watanabe et al ., 2015). Most of those studies rest on the presence of external pneumatic openings and, with the exception of Watanabe et al .…”

“…For example, the rarity of soft-tissue preservation requires paleontologists to frequently utilize anatomical correlates of preserved hard tissues to infer unpreserved soft-tissue characteristics of extinct taxa (e.g. Witmer, 1995;Wedel & Sanders, 2002;Watanabe et al 2015). In the field of paleoneurology (Edinger, 1929;Kochetkova, 1978) internal molds of the cranial cavity, called cranial endocasts (hereafter 'endocasts'), have provided crucial information on the brain morphology of extinct vertebrates (e.g.…”
