一个三维的，几乎完整的翼龙下颌骨从克拉托组（巴西东北部的早白垩世），阿拉里皮盆地，被描述为一个新的物种tapajarine tapejarid。塔佩贾林翼龙是一种特殊的无齿翼龙，其特征是颅嵴发达，喙向下，并被认为是食果的飞行爬行动物。虽然相对较好的代表性和分布，该集团的进化历史仍然知之甚少，其成员的内部关系也没有得到很好的理解。本文报道的新种，命名为塞阿叉趾虎Aymberedactyluscearensis gen.etsp.nov.，增加了关于该群体进化的新数据，关于它们的形态和地理起源。它不同于已知的tapejarids，因为其异常细长的关节后突和一个浅的窝在压上表现出独特的皱纹纹理。此外，它还展示了Tapejaridae内的一套基础和衍生条件，表明它们的形态特征可能是如何进化的，这些形式甚至比已经承认的更多样化。西萨无趾翼龙的发现为Tapejarinae的进化史提供了新的线索。
A three-dimensional and almost complete pterosaur mandible from the Crato Formation (Early Cretaceous of Northeastern Brazil), Araripe Basin, is described as a new species of a tapejarine tapejarid. Tapejarines are a particular group of toothless pterosaurs, characterized by well-developed cranial crests, downturned rostra, and have been proposed to represent frugivorous flying reptiles. Though comparatively well represented and distributed, the evolutionary history of the group is still poorly known, and the internal relationships of its members are not well understood. The new species here reported, named Aymberedactylus cearensis gen. et sp. nov., adds new data concerning the evolution of the group, concerning their morphology and geographical origin. It differs from known tapejarids due to its unusually elongate retroarticular process and a shallow fossa on the splenial exhibiting distinctive rugose texture. Furthermore, it exhibits a suite of basal and derived conditions within the Tapejaridae, demonstrating how their morphological traits probably evolved and that these forms were even more diverse than already acknowledged. The discovery of Aymberedactylus cearensis sheds new light on the evolutionary history of the Tapejarinae.
