Stable Isotope Diet Analysis Of Teleoceras Fossiger From The High Plains Of Kansas, Patrick J. Wilson
Stable Isotope Diet Analysis Of Teleoceras Fossiger From The High Plains Of Kansas, Patrick J. Wilson
Master's Theses
Stable isotope geochemistry provides a way of examining both modern and ancient ecosystems. One important use of stable carbon isotopes is to determine the amount of C3 versus C4 plant biomass in the diet of herbivorous mammals. C3 plants have a more negative stable carbon isotope ratio (δ13C) than C4 plants because of the different photosynthetic pathways each type uses. These different δ13C values are preserved in the hydroxyapatite of herbivores upon consumption of the different plant types. The purpose of this study it to use δ13C values from serial samples of tooth enamel from six isolated permanent molars of …
Mammalian Fauna From The Fullerton Gravel Pit (Ogallala Group, Late Miocene), Morton County, Kansas, Michael Anthony Calvello
Mammalian Fauna From The Fullerton Gravel Pit (Ogallala Group, Late Miocene), Morton County, Kansas, Michael Anthony Calvello
Master's Theses
The Fullerton Gravel Pit, Morton County, Kansas is one of many sites in western Kansas at which the Ogallala Group crops out. The Ogallala Group was deposited primarily by streams flowing from the Rocky Mountains. Evidence of water transport is observable at the Fullerton Gravel Pit through the presence of allochthonous clasts, cross-bedding, pebble alignment, and fossil breakage and subsequent rounding. Fluvial mechanisms also played an important role in the distribution of fossil material. When the fossils from the Fullerton Gravel Pit are placed in Voorhies Groups, it appears that a majority of them were removed from suspension gradually and …
