Comment:
Original 87Sr/86Sr data are from Zachos et al. (1999) data set: doi:10.1594/PANGAEA.695370. The 87Sr/86Sr ratios were normalized to NIST-987= 0.710248 (McArthur et al., 2001) by adjusting the values for Hole 748B by adding 4*10**-6. The 2 sigma values of Zachos et al. (1999) were adjusted to a minimum of 14 to reflect the maximum precision for multiple runs of the NIST-987 Sr standard. Ages were determined for the 87Sr/86Sr values using the look-up tables of McArthur et al. (2001). Minimum and maximum ages were determined using the 2sigma uncertainties and the look-up tables.
