Most knowledge of Late Mesozoic terrestrial vertebrate faunas comes from fossil deposits in the New World, Europe, and Asia, whereas from Africa there is little information based on only a few isolated localities. In particular the northeastern part of the continent has so far remained dramatically understudied. We propose to explore the poorly known fauna of Late Mesozoic terrestrial vertebrates of east Saharan Africa by performing palaeontological fieldwork in Upper Cretaceous sediments of central northern Sudan, which promise to provide invaluable insights into the patterns of vertebrate diversity in northeastern Gondwana shortly before the K/T extinction event. Fieldwork comprises the relocation and excavation of previously known localities but also the prospecting for new finds, as well as the digital and detailed record of stratigraphic position and palaeoenvironmental context of localities.

大多数关于晚中生代陆栖脊椎动物区系的知识来自新大陆、欧洲和亚洲的化石沉积，而来自非洲的信息很少，仅基于少数孤立的地点。特别是非洲大陆的东北部，迄今为止仍然严重缺乏研究。我们建议探索鲜为人知的动物群的晚中生代陆生脊椎动物的东撒哈拉非洲中部北方苏丹，这有望提供宝贵的见解，在冈瓦纳东北部的脊椎动物多样性的模式前不久的K/T灭绝事件进行古生物学野外工作。野外工作包括重新定位和挖掘以前已知的地点，但也勘探新的发现，以及数字和详细的记录地层位置和古环境的地方。
