Cortical bone remodeling in Amniota: a functional, evolutionary and comparative perspective of secondary osteons
(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 ...
Benthic Foraminifera Assemblages from Shallow-Water Ecosystems: Implications for Environmental Assessment and Monitoring
(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 ...
The plesiosaur: remarkable morphology, histology, and physiology
(2019-07-04)
In this dissertation, contributions to understanding the morphology, histology, and physiology of plesiosaurs, a major group of marine reptiles from the Age of Dinosaurs, are presented. By using comparative methods and new ......
Theropod dinosaurs from Thailand and Southeast Asia: phylogeny, evolution, and paleobiogeography
(2019-10-23)
Southeast Asia played an important role in dinosaur study during the Late Jurassic to mid-Cretaceous. Thailand is roughly in the third place in dinosaur discovery in Asia, after China and Mongolia. Nevertheless, there are ......
Funktionale Analyse von Fledertier-Gebissen (Chiroptera)
(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 ......
Bats (Mammalia: Chiroptera) are with about 1200 species in 18 families the second-largest order within the Mammalia after rodents and the only one with the ability for active flight. They have a nearly worldwide distribution ......

Biogeography and Diversity Hotspots of Larger Indo-Pacific Foraminifera: A Structural Faunal Analysis from Raja Ampat
(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 ...
Patterns of life history recorded in the dorsal rib histology of amniotes: and their implications for body size evolution and ecology of sauropod dinosaurs
(2019-06-06)
Dorsal ribs of tetrapods for centuries have never been in focus of scientific interest in any of the main areas of research in biology or paleontology. However, new insights into rib inner structures reveal the importance ...
Konstruktionsmorphologie hypsodonter Backenzähne bei rezenten und fossilen Rodentia (Mammalia)
(2019-06-12)
Die Backenbezahnung vieler herbivorer Säugetiere weist auf der Okklusalfläche Schmelzfalten oder Schmelzinseln auf, die die reibende Funktion der Bezahnung erhöhen. Ziel der vorliegenden Arbeit ist die Klärung der ......
Molar dentition of the docodontan Haldanodon (Mammaliaformes) as functional analog to tribosphenic teeth
(2019-06-18)
All extant mammals save the monotremes descend from an ancestor with tribosphenic tooth morphology, characterized by a distally situated crushing basin (talonid basin) on the lower and an interlocking cusp (protocone) on ......
Molarenbezahnung des Docodonten Haldanodon (Mammaliaformes) als funktionelles Analogon zu tribosphenischen Zähnen
Alle heutigen Säugetiere mit Ausnahme der Monotremen stammen von einem Vorfahren mit ......

Alle heutigen Säugetiere mit Ausnahme der Monotremen stammen von einem Vorfahren mit ......
The reproductive biology of Cretaceous oviraptorid dinosaurs and its implication for the origin of bird reproduction
(2018-11-13)
This dissertation aims to pioneer an integrative approach that includes all lines of evidence to comprehensively and in detail reconstruct the biology of an extinct animal. Specifically, the dissertation consists of several ...
