Fig. 2From: Mid-Cenozoic climate change, extinction, and faunal turnover in Madagascar, and their bearing on the evolution of lemursChanges in global temperatures during the Cenozoic. a Global temperature from 50 Ma to today. Smoothed values (red line) are generated by a 300-knot generalized additive model (GAM) with cubic splines of temperature over time. b Rate of change of global temperature from 50 Ma to todayBack to article page
