FIGURE 2. Stratigraphic section in the vicinity of Panaca that yielded vertebrate fossils (bone symbols). Sections are arranged according to the correlations in figure 7 of Lindsay et al. (2002). Note that we have not indicated any fossil site in the Little Hogback section, which is where we believe fossils were collected by Stock (1921). Small circles and X's to the right of the sections indicate magnetic polarity determinations (open circle = reversed polarity, closed circle = normal polarity, x = indeterminate polarity).
