Gross observation
The bony block obtained from 16NPCK-M009 was bisected along the medial wall to reveal the inner side of the nasal chamber. The cross-section of the lamina semicircularis and ethmoturbinals I and II were observed, as shown in Fig. 2. Upon removal of the skeletal tissues of the medial nasal turbinals (ethmoturbinal I and II), the laterally positioned turbinals became visible. The anatomical nomenclature used to identify the nasal turbinals was based on Ito et al. (2022) and supplemented by relevant references (Klima, 1999; Maier and Ruf, 2014).
