Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 22B
Abstract
Cone maturity is as follows- cone A (picture 1), immature; cone B, basal section (picture 2); cone C, immature (picture 3); cone D, immature (picture 4); cone E, basal section (picture 5); cone F, basal section (picture 6); cone G, immature (picture 7). Cone A and C were filled with brown coprolites. Cone G contained 4 golden coprolites. Plate 22B is a successive peel taken from the same coal ball as other plates labeled 22.
