Description and analysis of the complex structure of enamel can be facilitated through the application of a system of hierarchical levels of structural complexity. Five interdependent levels are distinguished. These are the levels of: 1) crystallites, 2) prisms, 3) enamel types, 4) schmelzmuster, and 5) dentition. This system provides a basis for analysis(More)
The functional interpretation of the cheek teeth and the mastication cycle of Lagomorpha are deduced from various aspects of tooth morphology of fossil and extant species. Mastication is composed of an almost orthal shearing and transverse grinding in a lingual direction. Shearing blades are not only indicated by facets but as well by thickened enamel. A(More)
To investigate the diversity of the enamel structures in rodent molars, the schmelzmuster of more than 270 genera from the various fossil and extant groups was investigated. Only three basic types of schmelzmuster were recognized. The most prominent one, the C-type, is characterized by a basal ring of lamellar enamel (BRLE) surrounding the molars at the(More)
Hunter-Schreger-Bänder (HSB) sind eine auffällige Struktur im Schmelz von Säugetierzähnen, die als Bruchsicherung verstanden werden kann. Eine einfache Methode zur Beobachtung der Bänder wird beschrieben. Die hellen und dunklen Bänder werden durch die unterschiedliche Orientierung der Schmelzprismen hervorgerufen. Die häufige Aufgabelung der HSB sowie der(More)
An additional method for the investigation of the microstructure of enamel is described using the teeth of Coryphodon, Uintatherium, Entelodon, and Crocuta. Under low magnification natural surfaces or sections of teeth display details of the enamel microstructure when the light guide effect of prisms is used. Under the same low magnification even more(More)
Among medium- to large-sized terrestrial ‘ungulates,’ there is often a relationship between increasing body size, correlated changes in diet, and increased complexity of the enamel microstructures [notably the development of Hunter-Schreger bands (HSB)]. An exhaustive survey of the enamel microstructures of living and extinct Hyracoidea demonstrates,(More)
