A Paramedian section of a skull of Crocidura russula (Coll. W. Maier). This figure shows the 3 ethmoturbinals filling the recessus ethmoturbinalis. The lamina terminalis is very elongated. B µCT images of the same skull. – Cross section 1510 is near the anterior end of the lamina terminalis. – Section 1700 shows the lamina terminalis in about the midth of the nasopharyngeal duct, which is ventrally closed by the soft palate (stippled line). Cross-section 2030 shows the posterior part of the recessus ethmoturbinalis with the tips of the hamuli pterygoidei. The wall of the braincase and the snout may be interpreted as a strong shell (see discussion).
