Applications of molecular fossils in lacustrinestratigraphy
MetadataShow full item record
Biomarkers, or the so-called molecular fossils, are used tentatively in the Eogene lacustrine stratigraphy study in the Jiyang Sub-basin. Notwithstanding the fact that unidentified microfossils or amorphism and acritarchae are widely distributed in lacustrine source rocks, molecular fossils are useful to identify the sources. It is helpful to reconstruct the palaeo-enviroment, palaeo-ecosystem and compartmentalize the stratigraphic sequence by using molecular fossils with which the existence and types of microbes including bacteria, archaea and certain algae can be identified.

A critical evaluation of how ancient DNA bulk bone metabarcoding complements traditional morphological analysis of fossil assemblagesGrealy, Alicia; McDowell, M.; Scofield, P.; Murray, D.; Fusco, D.; Haile, J.; Prideaux, G.; Bunce, Michael (2015)When pooled for extraction as a bulk sample, the DNA within morphologically unidentifiable fossil bones can, using next-generation sequencing, yield valuable taxonomic data. This method has been proposed as a means to ...
Factors controlling the abundance and carbon isotopic composition of land-plant derived compounds in crude oils.Murray, Andrew P. (1998)This thesis describes a study in petroleum geochemistry and specifically of the application of Land-plant derived hydrocarbons to elucidating source matter type, depositional environment and thermal maturity of crude oils. ...
Highly skewed sex ratios and biased fossil deposition of moa: ancient DNA provides new insight on New Zealand’s extinct megafaunaAllentoft, M.; Bunce, Michael; Scofield, R.; Hale, M.; Holdaway, R. (2010)Ancient DNA was isolated from the bones of 267 individuals of the extinct New Zealand moa (Aves: Dinornithiformes) from two late Holocene deposits [Pyramid Valley (PV) and Bell Hill Vineyard (BHV)]located 5.7 km apart in ...
