Temperature data during the Cenozoic. Modified from the
set in RPANDA, originally inferred
from delta O18 measurements.
A data frame with 17632 rows and 2 variables:
A numeric vector representing time since the beginning of the data
frame age, approximately 67 million years ago, in million years. We set this
from past to present as opposed to present to past since birth-death
paleobuddy consider time going in said direction.
A numeric vector representing temperature in degrees
celsius corresponding to time
t. Note there might be more than one
temperature for each time
t given the resolution of the data set.
