Funktionelle Morphologie und Abnutzungsmuster prätribosphenischer Molaren am Beispiel der Dryolestida (Mammalia, Cladotheria)
(2012-03-09)
Für die Dryolestida, primitive mesozoische Säugetiere, sind die mesiodistal verkürzten und buccolingual verbreiterten Molaren in Ober- und Unterkiefer kennzeichnend. Die Molaren sind in Form von alternierenden Dreiecken ...
Underwater flight in sea turtles and plesiosaurs: Dissection, muscle reconstructions, analog models, and finite element structure analyses inform on flipper twisting and muscle forces in plesiosaurs
(2020-08-13)
This dissertation contributes to our understanding of plesiosaur locomotion by providing foreflipper and hindflipper muscle reconstructions and studying aspects of their muscle physiology (functions, forces, muscle length ......
Climate- and Human-Induced Vegetation Changes in Northwestern Turkey and the Southern Levant since the Last Glacial
(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 ...
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 ......
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 ......

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 ......

Occlusion and Function of Triconodont Dentitions
(2020-12-18)
Over the last decades, many studies have focused on the tribosphenic molar and its functional aspects because it is considered to be a key innovation in mammalian evolution. Early triconodont dentitions have been examined ...
