摩洛哥的两个上古新世和一个下始新世地区(Ouarzazate盆地)产生了陆相组合，这些组合位于非洲板块古近纪罕见的两栖动物群中。这些藏品包括一种稀有的青蛙和非洲古近纪唯一已知的蜥蜴。上古新世的两个地区之一，Adrar Magorn 1，产生了一种不确定的无尾两栖动物和非洲中、新生代最多样化的鳞片岩组合。它已经产生了已知的最早的脊柱蛇类，以及来自非洲的最早的壁虎科、两栖类、特洛伊氏蛇科，也许还有博伊科。此外，标本代表了这块大陆上最后一种蝶齿类蜥蜴或最早的长齿蜥蜴。其中一个两栖动物代表了一个非常独特的新分类群，Todrasaurus gheerbranti gen。和sp.11月也有不确定的异形虫、裂片异形虫、马特索科和刺蛛科的存在。下始新世的动物群多样性不如上古新世，但有些分类群在这两个层次上都是共同的。与来自非洲板块的几乎所有其他古近纪两栖动物群相反，这些古新世和始新世组合包括陆生而不是水生的类群。(C)2006年爱思唯尔·马森公司。版权所有。
Two Upper Paleocene and one Lower Eocene localities from Morocco (Ouarzazate basin) have yielded terrestrial assemblages that stand among the rare herpetofaunas from the Paleogene of the African Plate. The collections include one of the rare frogs and the only lizards known from the Paleogene of Africa. One of the two Upper Paleocene localities, Adrar Mgorn 1, has produced an indeterminate anuran and the most diverse assemblage of squamates from the Mesozoic and Cenozoic of Africa. It has yielded the earliest known scolecophidian snake and the earliest Gekkonidae, amphisbaenians, Tropidophiidae, and perhaps Boidae from Africa. Moreover, a specimen represents either the last sphenodontian or the earliest acrodontan lizard from this continent. One of the amphisbaenians represents a very distinct new taxon, Todrasaurus gheerbranti gen. and sp. nov. Indeterminate scincomorphans, lacertilians, Madtsoidae, and Aniliidae are also present. The fauna from the Lower Eocene is less diverse than that from the Upper Paleocene, but some taxa are common to both levels. Contrary to nearly all other Paleogene herpetofaunas from the African Plate, these Paleocene and Eocene assemblages include taxa, that were terrestrial, not aquatic. (c) 2006 Elsevier Masson SAS.
