Having identified the Flattops One sandstones, Jasper Forest bed/Rainbow Forest Bed, and Camp Butte beds as all being stratigraphically distinct, it becomes clear that the strata referred to as the "Jim Camp Wash beds" by Heckert and Lucas [11] and Woody [12] actually occur at two separate stratigraphic levels (Figure 5, Figure 7 9).
A short-axis image of the PTN was visualized, captured, and stored at each of three separate levels, specifically 1 cm, 3 cm, and 5 cm proximal to the cephalad border of the medial malleolus (Fig. 1).
