Fig. 2. Carbon isotopic values (with error bars) of individual Precambrian microfossils from single stratigraphic horizons of three geologic units measured by ion microprobe mass spectrometry compared with those of the carbonate and total organic carbon measured in bulk samples of the same geologic units. Values plotted for carbonate and total organic carbon are from Strauss and Moore (1992) for microfossils from the Bitter Springs and Gunflint Formations, from House et al (2000) and those for microfossils from the Dresser Formation, from Ueno et al. (2001).
