Professors David De Vleeschouwer and Lawrence Percival, both former members of AMGCer's, authored a major review paper on Cyclostratigraphy and Paleoclimate that constitutes an major advance towards a fully astronomically-calibrated timescale for the entire Phanerozoic.
This paper summarizes the current status of Cyclostratigraphy and Astrochronology in the Paleozoic and Mesozoic and highlights several key elements related to uncertainties the astronomical solutions of precession, obliquity and eccentricity parameters, the global C cycle, major greenhouse/ice-house astronomical drivers, oceanic anoxia, and mass extinctions. A must read.
