Analysis of functional morphology in carnassial dentitions (Carnivora, Dasyuromorphia, Hyaenodonta)
Lang, Andreas (2023-08-14)Functional and structural changes in the evolution of carnassial teeth in the Carnivora, Dasyuromorphia and Hyaenodonta are analyzed by a combination of Occlusal Fingerprint Analysis, Dental Topographic Analysis (quantification ... -
Der Austausch der terrestrischen Säugetierfauna an der Pleistozän/Holozän-Grenze in Mitteleuropa
Fahlke, Julia M. (2009-09-09)Obwohl die Pleistozän/Holozän-Grenze als Ende der letzten Eiszeit und jüngstes Aussterbeereignis bereits ausgiebig erforscht ist, konnte bisher keine zufriedenstellend detaillierte räumliche und zeitliche Auflösung des ... -
Benthic foraminifera as proxies to infer paleoenvironmental conditions: Case studies from Western Siberia, and the Arabian and Mediterranean Sea
Trubin, Iaroslav (2024-01-22)Foraminifera are among the most important microfossils and invaluable tools for geosciences. Because of their small size and abundance, foraminifera are widely involved in applied studies where they are used for age-dating, ... -
Benthic Foraminifera Assemblages from Shallow-Water Ecosystems: Implications for Environmental Assessment and Monitoring
Fajemila, Olugbenga Temitope (2017-03-03)Benthic foraminifera have proved to be useful as present and past indicators in aquatic habitats because they are sensitive and react rapidly to environmental changes in various ecosystems. The knowledge of their modern ... -
Biogeography and Diversity Hotspots of Larger Indo-Pacific Foraminifera: A Structural Faunal Analysis from Raja Ampat
Förderer, Esther-Meena (2018-07-05)This thesis is the first comprehensive study on the species-rich benthic foraminiferal fauna of Raja Ampat (Indonesia) and the first to evaluate the biogeographic richness patterns and faunal provinces of recent Indo-Pacific ... -
Bone histology and growth of the prosauropod dinosaur Plateosaurus engelhardti MEYER, 1837 from the Norian bonebeds of Trossingen (Germany) and Frick (Switzerland)
Klein, Nicole (2005)Predominately long- and flat bones of the prosauropod <i>Plateosaurus engelhardti</i> from the Norian localities of Trossingen and Frick were sampled for paleohistological study. Both localities yield rich material of adult ... -
Changing distribution patterns of selected conifers in the Quaternary of Europe caused by climatic variations
Terhürne-Berson, Ruth (2005)Extreme climatic variations in the Quaternary of Europe did not only lead to an intense reduction of plant diversity, but also to significant changes in plant distribution. It is the aim of this work to exemplary investigate ... -
Climate- and Human-Induced Vegetation Changes in Northwestern Turkey and the Southern Levant since the Last Glacial
Miebach, Andrea (2017-04-20)Northwestern Turkey and the southern Levant are key regions for studying vegetation and climate developments during migration phases of modern humans and the origin and expansion of agriculture. Both regions have a long ... -
Comparative bone histology of the turtle shell (carapace and plastron): implications for turtle systematics, functional morphology and turtle origins
Scheyer, Torsten Michael (2007)The bone histology of the turtle shell is valuable for addressing osteoderm and shell formation, reconstruction of fossil integumentary soft-tissue structures, phylogenetic hypotheses and functional aspects of the turtle ... -
Cortical bone remodeling in Amniota: a functional, evolutionary and comparative perspective of secondary osteons
Mitchell, Jessica (2017-05-15)In this dissertation, contributions to understanding the formation, function and evolution of secondary osteons are presented. By using comparative methods and including fossil taxa, new insights are developed. I analyze ... -
Diversity of feeding and pollination strategies of Mesozoic beetles
Bao, Tong (2020-08-23)Beetles (Order: Coleoptera) as the most diverse and successful animals on the earth, comprise about 400,000 species, constituting almost 40% of described insects and a quarter of all animal species. They are distributed ... -
Estimating sauropod body mass and gait: by the analysis of recent and fossil tetrapod tracks with photogrammetry and soil mechanics
Läbe, Sashima (2017-08-15)This dissertation presents an analysis of recent and fossil tracks with quantitative and in-terdisciplinary methods for estimating the body mass and locomotion of a sauropod trackmaker. By employing methods from natural ... -
Evolutionsstadien der Kaufunktionen früher Artiodactyla
Schwermann, Leonie C. (2016-09-13)Ein differenziertes Gebiss mit spezialisierten Molaren und deren Mastikation sind Merkmale der Säugetiere. Besonders die postcanine Bezahnung zeigt spezifische Anpassungen an eine effiziente Zerkleinerung der jeweiligen ... -
Faunal Provinces and Patterns of Diversity in Late Cretaceous (Santonian-Maastrichtian) Larger Foraminifera
Goldbeck, Elke J. (2008)A detailed biogeographical analysis of the global distribution of 25 different genera of larger symbiont-bearing foraminifera from the Late Cretaceous reveals that they exhibit distinct patterns. On a generic level, the ... -
Fossil record and new aspects of evolutionary history of Calcium biomineralization and plant waxes in fossil leaves
Malekhosseini, Mahdieh (2023-10-30)Calcium oxalate (CaOx) is one of the most common bio-minerals in extant plants. It plays a major role in a better understanding of plant taphonomy, environmental effects and evolution of calcium minerals in fossil plants. ... -
Functional analysis of molars in “symmetrodontan” mammals
Plogschties, Thorsten (2020-03-10)The “symmetrodontan” molar pattern is characterized by triangulation of the main cusps in combination with a reversed-triangle occlusion. In the fossil record, the “symmetrodontan” molar pattern occurred in various taxa ... -
Funktionale Analyse von Fledertier-Gebissen (Chiroptera)
Hielscher, Romina Christin (2018-04-13)Fledertiere (Mammalia: Chiroptera) sind mit ungefähr 1200 Arten in 18 Familien die zweitgrößte Säugetierordnung nach den Nagetieren und die einzige, die zum aktiven Flug fähig ist. Sie sind nahezu weltweit verbreitet und ... -
