Geochemical taphonomy of shallow marine vertebrate assemblages

摘要: Abstract Combined histological and geochemical analyses demonstrate complex processes leading to preservation of microbially altered bone. In certain situations, a chemical microenvironment distinct from surrounding pore waters is developed maintained within the The bone acts as closed system, hence palaeoenvironmental interpretations based on fossil apatite chemistry may not accurately reflect overall conditions sedimentary deposits where bones were buried. Geochemical techniques variance in trace element compositions different assemblages can be used measure relative degree mixing or taphonomic averaging marine vertebrate assemblages.
