"Insectivore" mammal skulls, ventral view

Photographs of ventral views of "insectivore" mammal skulls (Afrosoricida, Erinaceomorpha, Soricomorpha and Notoryctemorphia) from the American Museum of Natural History (AMNH) and the Smithsonian Institute (SI). I can provide a list of the species identities corresponding to each specimen ID number. Alternatively, species may be identified by searching the online museum databases for the specimen ID number. I photographed the skulls on a flat plane relative to the camera and the scale bar has 1mm as the smallest demarcation. Images are grey scale TIF files labelled with the museum specimen ID number, the specimen identity (cranial) and view (ventral) along with the date that I took the photograph. Some specimens were photographed three times, re-positioning the skull in between each picture. They are labelled with the same museum specimen number and then _1A, _2A and _3A to indicate that they are replicate pictures of the same skull. These photos form part of my research on morphological diversity in tenrecs compared to other mammal groups.

本数据集收录来自美国自然历史博物馆（American Museum of Natural History，AMNH）与史密森学会（Smithsonian Institute，SI）的‘食虫类’哺乳动物颅骨腹面视图照片，类群涵盖非洲猬目（Afrosoricida）、猬形目（Erinaceomorpha）、鼩形目（Soricomorpha）以及袋鼹目（Notoryctemorphia）。我可提供每份标本编号对应的物种鉴定信息；亦可通过在博物馆在线数据库中检索标本编号来获取物种信息。拍摄时颅骨与相机镜头处于同一平面，标尺的最小分度为1毫米。图像为灰度TIF格式文件，文件名包含博物馆标本编号、标本鉴定信息（颅骨）、拍摄视角（腹面）以及拍摄日期。部分标本被拍摄三次，每次拍摄前均重新调整颅骨的摆放位置；这类重复照片采用相同的博物馆标本编号，后缀_1A、_2A与_3A以标识为同一份颅骨的复刻照片。本批照片为我针对马岛猬类与其他哺乳动物类群开展的形态多样性研究的组成部分。
