Osteology and taxonomy of the arthrodires from the Kellwasser facies (Frasne, Upper Devonian) of southern Morocco and Bad Wildungen, Germany, with an analysis of the palaeoenvironment including the microvertebrates

首次发现的节足类（Placodermi）从Kellwasser相的南部摩洛哥将研究其骨骼学和分类学，并与标本从Kellwasser石灰石的Bad Wildungen（Germary）。此外，还将研究以下目标：1）摩洛哥新发现的牙形刺和其他微脊椎动物标本的地层位置。2)根据Kellwasser相节肢动物的埋藏学，对古环境和沉积体制作出结论。3)Tafilalt台地和Tafilalt盆地（摩洛哥南部）之间过渡带的沉积学以及节肢动物和微脊椎动物组合从浅水沉积物到深水沉积物的变化。4)对冈瓦纳大陆沿着节肢动物组合的关系进行了重建。和劳鲁西亚的南部边缘

First discoveries of arthrodires (Placodermi) from the Kellwasser facies of southern Morocco will be studied with respect to their osteology and taxonomy and compared with specimens from the Kellwasser limestone of Bad Wildungen (Germary). In addition the following objectives shall be investigated: 1) The stratigraphical position of the new discoveries from Morocco and the specimens from Bad Wildungen based on conodonts and other microvertebrates. 2) Conclusions on the palaeoenvironment and the depositional regime based on the taphonomy of the Kellwasser facies arthrodires. 3) The sedimentology in the transitional zone between the Tafilalt Platform and the Tafilalt Basin (southern Morocco) and the changes of the arthrodire and microvertebrate assemblages from shallow into deep water deposits. 4) The reconstruction of the relationships between the arthrodire assemblages along the northern margin of Gondwana... and the southern margin of Laurussia...
