Mass Extinctions and Environmental Implications

Abstract

Kliti will present research findings from her team using a multidisciplinary approach  (ranging from biomarkers, stable carbon and hydrogen isotopes of molecules, palynology, paleontology, petroleum systems and sedimentary geochemistry). She will provide a summary of their findings published in Science (Grice et al., ), Nature Scientific Reports (Melendez et al., ), Geology (Jaraula et al.,), Geochimica et Cosmochimica Acta (Williford et al.,) and Earth and Planetary Science Letters (Tulpani et al.; Grice et al., Nabbefeld et al.,).
Kliti will address three critical questions during her seminar.
1. When and how on Earth was Life Nearly entirely Wiped-Out?

2. How similar were three of the five mass Extinctions on Earth? (end- Permian, end-Triassic and Late Givetian – Early Frasnian

3. How did exceptional preservation of biological material occur? (The most extensive diagenetic continuum of 380 million years old (including intact geomolecules-sterols).
