More than 250 Pleistocene vertebrate trace fossil sites have been identified on the Cape south coast of South Africa in aeolianites and cemented foreshore deposits. These discoveries, representing the epifaunal tracks of animals that moved over these sand substrates, complement traditional body fossil studies, and contribute to palaeo-environmental reconstruction. Not described in detail until now, but also important faunal components, are the infaunal traces of animals that moved within these sandy substrates. Six golden mole burrow trace sites (Family Chrysochloridae) have been identified on the Cape south coast. In addition, three sites, including one on the Cape southeast coast, have been identified that show evidence of sand-swimming, probably by a golden mole with a means of locomotion similar to that of the extant Eremitalpa genus. Such traces have not been described in detail in the global ichnology record, and merit the erection of a new ichnogenus Natatorichnus, with two ichnospecies, N. subarenosa ichnosp. nov and N. sulcatus ichnosp. nov. Care is required in the identification of such traces, and the orientation of the trace fossil surface needs to be determined, to avoid confusion with hatchling turtle tracks. Substantial regional Pleistocene dune environments are inferred from these sand-swimming traces.

来自南非开普海岸的更新世金鼹鼠和游沙痕迹化石

已在南非开普南海岸的风积岩和胶结前滩沉积物中发现了 250 多个更新世脊椎动物踪迹化石遗址。这些发现代表了在这些沙底上移动的动物的表层动物足迹，补充了传统的身体化石研究，并有助于古环境重建。直到现在还没有详细描述，但重要的动物群成分是在这些沙质基质中移动的动物的动物踪迹。已在开普南海岸确定了六个金鼹鼠洞穴踪迹点（金黄鼹科）。此外，已经确定了三个地点，包括一个在开普敦东南海岸的一个地点，这些地点显示出沙游的证据，可能是由一种具有与现存运动方式相似的运动方式的金鼹鼠造成的。埃雷米塔尔帕属。这些痕迹在全球 ichnology 记录中没有详细描述，值得建立一个新的 ichnogenus游鱼, 有两个 ichnospecies,N. subarenosa伊奇诺普。十一月和N. sulcatus伊奇诺普。十一月 在识别此类痕迹时需要小心，并且需要确定痕迹化石表面的方向，以避免与孵化龟的痕迹混淆。从这些游沙痕迹推断出大量的区域更新世沙丘环境。
