Dorsal view and ‘pseudo X-rays’ of the same specimens of Crocidura russula (SMF 95044) and Sorex araneus (SMF 82598). In both specimens, the cupula nasi posterior is exactly in the same position in comparison with the basicranial length (stippled line). However, the jaw joint of Sorex lies somewhat more rostrally than that of Crocidura (anterior dashed lines in the pseudo-X-rays). In Crocidura, the alisphenoid originates more caudally at the basisphenoid, and its wing is less inclined and is more exposed in dorsal perspective. In Sorex the foramen lacerum medium extends more rostrally.
