瓦利斯危机导致了大多数在晚中新世中期和早期成功定居在欧洲的人科动物的灭绝，包括森林古猿、安卡拉古猿和希腊古猿。这一事件的发生时间为9.6 Ma，比7-8 Ma时C4草的蔓延和地球仪大部分地区森林的退缩早了100多万年。在特拉萨剖面（瓦勒斯-佩内德斯盆地）发现的大型植物群遗迹为与人科动物灭绝相关的植被变化的性质提供了新的线索。这一部分提供了丰富的晚瓦利斯期脊椎动物群，并已被准确地定年为9.2 - 9 Ma的古地磁。因此，它提供了瓦利斯危机后占据该地区的植被种类的最佳指示。有人建议，晚中新世西欧人科动物的灭绝与草的传播无关，但以落叶树木为主的植物群的显着增加。(C)2003爱思唯尔有限公司。保留所有权利。
The Vallesian Crisis involved the extinction of most of the hominoids that settled successfully in Europe during the middle and early Late Miocene, including Dryopithecus, Ankarapithecus and Graecopithecus. This event has been dated at 9.6 Ma, predating by more than one million years the spread of the C4 grasses and the retreat of forests over large parts of the globe at 7-8 Ma. The finding of macrofloral remains in the Terrassa section (Valles-Penedes Basin) sheds new light on the nature of vegetational change associated with the hominoid extinction. This section presents an abundant late Vallesian vertebrate fauna and has been accurately dated at 9.2 - 9 Ma by paleomagnetism. Therefore, it provides the best indication of the kind of vegetation that occupied the area after the Vallesian Crisis. It is suggested that the extinction of the late Miocene Western European hominoids was not related to the spread of grasses, but to a significant increase of a floral association dominated by deciduous trees.
