Isotopic measurements of 3 foraminifer species from ODP Hole 171-1050C, supplement to: Isaza-Londoño, Carolina; MacLeod, Kenneth G; Huber, Brian T (2006): Maastrichtian North Atlantic warming, increasing stratification, and foraminiferal paleobiology at three timescales.

Analysis of 944 single specimens of three species of late Maastrichtian planktonic foraminifera (Racemiguembelina fructicosa, Contusotruncana contusa, and Rugoglobigerina rugosa) from 38 samples spanning the last 3 Myr of the Cretaceous shows consistent isotopic trends through time, consistent isotopic differences among taxa, and high within-sample isotopic variability throughout. Within-sample variability does not change systematically through time for any taxon, but average d18O values decrease by approx. 1.5 per mill, and average d13C values diverge up...
