Crocidura zimmermanni and Crocidura suaveolens are insectivorous mammals belonging to the extant shrew fauna of Crete. In particular, the C. zimmermanni has probably been present since the early Pleistocene. C. suaveolens, a species recently (i.e. in historical times) introduced to Crete, has constrained C. zimmermanni to the higher altitudes of the island. The lack of clear external morphological characters has caused a long history of confusion between the two. Within the framework of this thesis, we will employ high-resolution Computed Tomography (CT) imaging, aiming at finding distinctive characters between the two shrews through the acquisition of morphological information from skull bones and teeth. The recorded 3D reconstructions of the skull will provide precise assessments of the molar length, the jaw width as measured between the first and second molar, and the condylomaxillary length between the canine and the third molar. Furthermore, we are planning to determine the height of the cingulum above the end of the teeth in the investigated mammals. Each of the characters mentioned, or their combination, may allow for a safe distinction between the two species. The rapid and inexpensive morphological examination through CT is expected to provide additional evidence as regards the reliable classification of the animals, complementing the state-of-the-art molecular analysis methods.
