A new florula, dominated by angiosperm leaves, is reported from the Upper Cretaceous (Turonian?) Malihah Formation of Saudi Arabia. The leaves are fragmentary preserved as impressions with a rust coloured, mineral coating, thus it is only possible to describe the best-preserved leaf forms as morphotaxa for the time being. Eight angiosperm and two gymnosperm morphotypes can be distinguished. Morphologically the flora exhibits more similarities to Aptian – Cenomanian floras than to Turonian floras from northern Gondwana. Knowledge about this florula fills a regional gap in our knowledge about Cretaceous floras from the Arabian Peninsula and its surroundings.

来自沙特阿拉伯上白垩统的一种以被子植物为主的小花

据报道,在沙特阿拉伯的上白垩纪(Turonian?)Malihah 组中发现了一种以被子植物叶为主的新植物群。叶子被残存为带有铁锈色矿物涂层的印记,因此暂时只能将保存最完好的叶子形式描述为 morphotaxa。可以区分八种被子植物和两种裸子植物形态类型。在形态上,该植物群与阿普提安 – 森诺曼尼亚植物群的相似性比与冈瓦纳北部的土伦植物群相似。关于这种植物群的知识填补了我们对阿拉伯半岛及其周边地区白垩纪植物群知识的区域空白。
