Pacing of Paleozoic Macroevolutionary Rates by Milankovitch Grand Cycles [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance There has been long-standing debate about the relative roles of intrinsic biotic interactions vs. extrinsic environmental factors as drivers of biodiversity change. Here, we show that, relatively early in the history of complex life, Milankovitch “grand cycles” associated with astronomical rhythms explain between 9 and 16%

Filtering of Milankovitch Cycles by the Thermohaline Circulation

Journal of Climate, 1999
A low-order, basin-averaged, coupled atmosphere‐ocean paleoclimate model is developed and the results from a 3.2-Myr model paleointegration described. A three-basin version of the Wright‐Stocker ocean model is used to compute the thermohaline circulation component of the climate system, with a six-basin energy balance atmosphere coupled to the ocean ...

Uniformity of the Upper Famennian Milankovitch Cycle in China

Chinese Science Bulletin, 2000
Research on chemo-biostratigraphy reveals that the periodic fluctuation of Ce/La ratios in carbonate sequence may reflect Milankovitch 100 ka eccentricity cyclicity. The Ce/La curve of the upper Famennian of Huangmao (Guangxi) may be well correlated to that of Muhua (Guizhou) and of Mid-Tarim (Xinjiang).
