Moderate to Elevated Atmospheric CO2 During the Early Paleocene Recorded by Platanites Leaves of the San Juan Basin, New Mexico

This data repository includes (1) All data from modern Platanus specimens and Paleocene fossil Platanites specimens from the San Juan Basin, New Mexico, USA used to produce modern and paleo-CO2 estimates and (2) the input files used to run the Franks et al. (2014) leaf gas-exchange model. The model was run using the R script of Kowalczyk et al. (2018). The R script is available in Kowalczyk et al. (2018) supplementary materials: https://doi.org/10.1029/2018PA003356.
