From: Reassessing the temporal evolution of orchids with new fossils and a Bayesian relaxed clock, with implications for the diversification of the rare South American genus Hoffmannseggella(Orchidaceae: Epidendroideae)

Figure 4

Temperature curve over the past 65 million years (adapted from Zachos et al.[40]), illustrating the different results obtained here using BEAST as compared to previous estimates under the Penalized Likelihood algorithm. (A): Mean age of the major diversification of Orchidaceae (subfamilies Orchidoideae and Epidendroideae) as estimated by Ramirez et al. [4] using PL. (B): approximate median age of these clades estimated here using BEAST. (C): median age of the South American genus Hoffmannseggella in the Late Miocene, estimated here. The temperature scale is relative to the current mean global temperature ([41] provides an explanation and expanded data, but not a mean temperature curve).
