FIGURE 2 in Fruits, seeds and flowers from the Puryear clay pit (middle Eocene Cockfield Formation), western Tennessee, USA
FIGURE 2. Simplified stratigraphic column of the middle Eocene Claiborne Group in northern Mississippi and western Tennessee (after Dockery, 1996). Specimens examined in this paper were collected from the Cockfield Formation at the Puryear locality (P), Tennessee. Specimens from other localities used for comparison were collected from the Tallahatta Formation at the Bovay and Bolden localities (BB), Mississippi and the Cockfield Formation at the Warman clay pit (W; stratigraphically lower than the Puryear locality), Tennessee.
