项目摘要
In recent years, the upper Permian of the Dead Sea region (Jordan) has yielded a rich and varied flora. This flora is of special interest because: (1) it is one of the very few rich and diverse late Permian floras, (2) of its superb preservation with excellent cuticles which enable whole-plant reconstructions, (3) it consists of a mixture of elements from different floral provinces, i.e. Euramerica, Cathaysia and Gondwana, and (4) of the precocious occurrences of major plant clades so far only known from the Mesozoic. Funds are requested for fieldwork in two newly discovered, hardly exploited localities in the Umm Irna Formation and for studying this material. Rhipidopsis foliage is particularly common in these localities and found in close association with a peculiar type of fructification that is so far unknown. Rhipidopsis is commonly regarded as an early ginkgophyte. However, a first screening shows that the stomata are very different from those of ginkgophytes and that the associated fructification looks very Caytonia-like. The Caytoniales are a small Mesozoic group of seed-ferns that is often regarded as ancestral to the flowering plants. The aim of this small project is to collect new material in order to test the hypothesis that Rhipidopsis is of caytonialean affinity.
近年来,死海地区(约旦)的上二叠统产生了丰富多样的植物群。这种植物群具有特殊的意义,因为:(1)它是极少数的丰富多样的晚二叠世植物群之一,(2)它保存得极好,具有良好的保护作用,能够进行全植物重建,(3)它由来自不同植物区系的成分组成,即欧亚大陆,华夏大陆和冈瓦纳大陆,(4)迄今为止只知道中生代的主要植物分支的早熟出现。申请资金用于在Umm Irna组两个新发现的、几乎未开采的地点进行实地考察和研究这些材料。Rhipidopsis叶子在这些地区特别常见,并且与一种迄今为止未知的特殊类型的果实密切相关。Rhipidopsis通常被认为是早期银杏植物。然而,第一次筛选表明,气孔是非常不同的银杏植物和相关的果实看起来非常Caytonia一样。Caytoniales是一个小型的中生代种子蕨类植物群,通常被认为是显花植物的祖先。这个小项目的目的是收集新的材料,以测试假设Rhipidopsis是caytonialean亲和力。
