FIGURE 1. Miocene stratigraphy and temporal distribution of vertebrate faunas. Stratigraphy primarily based on Galloway et al. (1986) and reflects marine biostratigraphic control in down-dip locations. Symbol in the Catahoula Formation identifies approximate age of multiple Ar/Ar radiometric dates (Jordan et al., 2019). Blue bar highlights the Ba1 North American Land Mammal Age (NALMA). Time scale from Hilgren et al. (2012); Raffi, Wade and Pälike (2020). O = Orellan, W = Whitneyan, Ar = Arikareean, He = Hemingfordian, Ba = Barstovian, CL = Clarendonian, H = Hemphillian. Names shown for the vertebrate assemblages are local fauna names except for Lapara Creek Fauna (composed of multiple local faunas), and Belts Creek (single locality with three known taxa).
