The Miocene sands of the Swiss Jura Mountains, long exploited in quarries for the construction industry, have yielded abundant fossil remains of large mammals. Among Deinotheriidae (Proboscidea), two species, Prodeinotherium bavaricum and Deinotherium giganteum, had previously been identified in the Delémont valley, but never described. A third species, Deinotherium levius, from the locality of Charmoille in Ajoie, is reported herein for the first time in Switzerland. These occurrences are dated from the middle to the late Miocene, correlating to the European Mammal biozones MN5 to MN9. The study is completed by a discussion on the palaeobiogeography of deinotheres at the European scale.

瑞士侏罗山脉中新世恐鸟科的记录（瑞士侏罗州）

瑞士侏罗山脉的中新世砂岩长期被用于建筑业的采石场，产生了大量大型哺乳动物的化石遗骸。在恐禽科 (Proboscidea) 中，有两个物种Prodeinotherium bavaricum和Deinotherium giganteum之前曾在德莱蒙山谷中被发现，但从未被描述过。第三个物种Deinotherium levius来自 Ajoie 的 Charmoille 地区，这是瑞士首次在此报道。这些事件可追溯到中新世晚期，与欧洲哺乳动物生物区 MN5 至 MN9 相关。该研究是通过对欧洲尺度上恐兽类的古生物地理学的讨论而完成的。
