Fig. 1 in Dietary niches of creodonts and carnivorans of the late Eocene Cypress Hills Formation

Fig. 1.—Creodont and carnivoran species richness during the Eocene. Time is millions of years ago (Ma). Vertical dashed line indicates the age of the Calf Creek Local Fauna. Light gray indicates creodont species richness. Dark gray indicates carnivoran species richness. The data were downloaded from the Paleobiology Database on March 2018, using the group name 'mammalia' and the following parameters: time intervals = Cenozoic, region = North America, paleoenvironment = terrestrial. Species richness plot was constructed using the paleotree R package (Bapst 2012).
