Calcareous nannofossils assemblages for provenance analysis of European paintings: From the sample preparation to the assemblage comparison
Jaques, Victory Armida Janine ; Holcová, Katarína (advisor) ; Caruso, Francesco (referee) ; Oszczypko-Ciowes, Marta (referee)
This PhD thesis is a commentary of four studies published and a fifth study submitted in peer reviewed and impacted scientific journals. Three studies are methodological work for the preparation of painted micro-samples to improve the measurements accuracy, the samples visualisation, and the combination of measurements methods. The two other papers focus on the fossil assemblages determination and comparison between reference historical areas and original paintings. This work is divided into three main parts, namely the introduction, the methods, and the calcareous nannofossils assemblages. In the introduction, detailed explanations are given about the paintings, historical materials, trade roads, what are nannofossils, how and why to use them. In the methods section, developed preparatory methodologies are summarised, and the most important results are explained. In the third part, the nannofossils assemblages, the differences between the assemblages from different areas in Europe compared to original paintings are explained and correlated to the literature. The impact of the preparatory methods on the results is discussed, and a conclusion is drawn from it in the context of painted artefacts in the Cultural Heritage field are unique, and so are the micro-samples from them. To extract most...

Oyster bioherms in the Bohemian Cretaceous Basin
Rantuch, Jakub ; Košťák, Martin (advisor) ; Frank, Jiří (referee)
Frustration from shape and size variability of oyster's species Rhynchostreon suborbiculatum (Lamarck) is long known phenomenon. In current state of his systematic it is not possible to consider it fully satisfying. Is it is shown in study of genus Gryphaea by Jones and Gould (1999), that application of modern analytical methods, undoubtly lightens long-darkned places of evolution process. Idea of Videt and Neraudeau (2003), that shape variability of Rhynchostreon suborbiculatum (Lamarck) probably also mirrors heterochronic processes, introduces inspirative and good foundation for future research in this field. Occurence of this oyster is proved from huge range of sites in Bohemian Cretaceous Basin area. It is combination of rich occurance, unique preservation and variability of lithological settings, which gives us unique starting point for next step to solve significant problem. Based on population analyses consisting of biometrical studies supported by oxygen isotope analyses, in future, it will be possible to reach sufficient conclusions of this issue, and progress in our knowledge.
