Morphological disparity in CP seen in elephant, tarsier, platypus and dog skull models.

CP morphological disparity viewed in 3D models constructed with Mimics and 3-matic software from high-resolution CT scans. Yellow top center: CP of the African elephant (Loxodonta africana), viewed here from brain case, has the largest absolute and relative surface area and ~1,000 foramina for passage of olfactory nerves to the brain. Extreme reduction of complexity is evident in CPs of the tarsier (Tarsius syrichtus) (green, lower left) and platypus (Ornithorhynchus anatinus) (orange, bottom center) CPs. Dog (Canis familiaris) CP (blue, lower right). The inset superimposed over elephant model shows tarsier, platypus and dog CPs to scale with the elephant’s CP.本数据集展示了通过高分辨率计算机断层扫描（CT）采集数据、借助Mimics与3-matic软件构建的三维模型中呈现的筛板（Cribriform Plate，CP）形态差异。图中上中部的黄色标注对象为非洲象（Loxodonta africana）的筛板，从颅腔视角呈现，其具备最大的绝对表面积与相对表面积，且拥有约1000个供嗅觉神经通入大脑的筛孔。跗猴（Tarsius syrichtus，绿色，左下）与鸭嘴兽（Ornithorhynchus anatinus，橙色，底部中央）的筛板结构复杂度显著降低。家犬（Canis familiaris）的筛板以蓝色标注，位于右下侧。叠加于大象模型之上的内嵌插图，展示了跗猴、鸭嘴兽与家犬的筛板与大象筛板的比例尺寸对应关系。
