In the absence of any restored soft tissues, modeled airflow bypasses the olfactory region, which is not realistic. By modeling a respiratory turbinate (in this case, an ostrich-like branched concha) attaching to the preserved bony ridge, realistic olfactory airflow is modeled. It's also likely that the nasal structures functioned to cool blood that was destined for the brain region. This is largely the work of Jason Bourke (Ohio University) to accompany an article published in the Anatomical Record (2014) by Bourke, Porter, Ridgely, Lyson, Schachner, Bell, and Witmer. Research supported in part by the NSF-funded Visible Interactive Dinosaur project, WitmerLab at Ohio University. For more on this project, visit http://bit.ly/1tksIgs.
