On the Inside of Travellers: Morphology of Early Juvenile Ammonites And Their Implications for Faunal Dynamics in the Late Cretaceous

菊石总科化石丰富、分布广泛，甚至广受欢迎，其中许多化石可用作精确的生物地层学指标。由于缺乏柔软部分的保存，人们对生物体本身知之甚少。如果更好地将它们理解为生物体，它们的丰富程度可以代表气候和古海洋地理变化对地球历史上微生物的影响。拟议项目的目的是对最内侧螺旋体的形态--即疑似洋流漂移的阶段--及其与所考虑物种在整个晚白垩世几个时间片中的古生物地理分布的联系进行物种研究和相互关联。这样，就可以得出晚白垩世许多环境变化对菊科生物的影响的结论。将使用研磨层析成像，同时测试进一步的应用，如化石的虚拟存储，例如在不稳定类型的保存中。

Ammonoidea are abundant, widespread and even popular fossils, many are useful as precise biostratigraphic indices. Due to the lack of soft part preservation, little is known about the organism itself. Ammonoidea in their richness could provide a proxy for the impact of climatic and palaeoceanograpic changes on microorganisms in Earth history, if they were better understood as organisms. The aim of the proposed project is a species-based study and correlation of the morphology of the innermost whorls, i.e. the suspected phase of drift in oceanic currents, and its connection with the palaeobiogeographical distribution of the considered species in several time slices throughout the Late Cretaceous. Like that, conclusions on the impacts of the many environmental changes of the Late Cretaceous on the ammonoidea as organisms can be drawn. Grinding tomography will be used and at the same time tested for further applications such as virtual storage of fossils, e.g. in unstable types of preservation.
