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).
