About 55 Myr ago, a brief period known as the Late Paleocene thermal maximum (Zachos et al., 1993) is defined in marine and terrestrial records by a sudden increase in proxy temperature estimates and a very large decrease in the ratio of to (Figure 13). Most of the carbon isotope shift appears to have occurred within a period of a few thousand years (Norris and Rohl, 1999), suggesting that the cause might have been a redistribution of carbon from the terrestrial biosphere to the oceans and atmosphere. But the magnitude of the shift, —2.5%o to —3%o, would have required the transfer of an amount of terrestrial organic carbon equivalent at least to virtually the entire modem terrestrial biosphere,... 

Figure 13 High-resolution carbon isotope records showing the anomaly corresponding to the Late Paleocene Thermal Maximum. The data are from three widely separated Ocean Drilling Program cores (Kennett and Stott, 1991 Bralower et al., 1995 Bralower et al., 1997) plotted on a common depth scale with the minimum at 0.0 m (Dickens (2001) reproduced by permission of the American Geophysical Union from Natural Gas Hydrates Occurrence, Distribution, and Detection, 2001, pp. 19-38 (figure 1)).
