Guy M. Narbonne, FRSC
My research centers on the origin and early evolution of animals and their ecosystems through the Neoproterozoic and into the Cambrian. These studies are carried out at the interface between paleontology, sedimentology, and geochemistry to elucidate how the early evolution of animals was interrelated with equally profound global physical and chemical changes (including global “snowball” glaciations and a major increase in atmospheric oxygen) during this critical interval in Earth evolution. My research over the past three decades has focussed on the Ediacara biota, Earth’s first experiment in complex multicellular life, with studies currently underway in Newfoundland, NW Canada, and Namibia. I have also done extensive research on the Neoproterozoic-Cambrian boundary and the Cambrian “explosion” of animal life, and on Proterozoic reefs and other carbonates. All of this work requires a finely calibrated time scale, and I have worked with others to define the international standard (GSSP) for the Cambrian Period (Narbonne et al., 1987) and the newly named Ediacaran Period (Knoll et al., 2006), and continue to be active in Neoproterozoic subdivision. I am also active in public outreach, including appearing in recent documentaries by David Suzuki (“The Nature of Things”, 2007) and Sir David Attenborough (“First Life with David Attenborough”, 2010), and working towards nomination of Mistaken Point as a UNESCO World Heritage Site.

I accept students with backgrounds in geology and/or biology, and tailor their projects to match their specific background skills. All of my projects involve fieldwork. My current students and their projects are listed below:
