Abstract
Geochemistry has become increasingly important to the field of paleontology. This thesis comprises two geochemical case studies examining questions at very different scales. The first examines possible controls on the formation of deposits where exceptional preservation of non-biomineralized tissues occurs throughout the Phanerozoic by the creation and analysis of a database of Phanerozoic Konservat-Lagerstatten. Potential controls examined include the influence of marine geochemistry, the availability of fossiliferous strata and evolutionary events. The second case study involves the application of Raman microspectroscopy in pathology and paleopathology. Raman microspectroscopy is used to demonstrate biotic origin for a new type of trace fossil, and to study the mineralogical changes that occur in bone presenting with osteomyelitis and hyperplastic bone marrow disease.
