Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 60A
Abstract
Cone maturity is as follows- cone A, immature (picture 1); cone B, mature (picture 2); cone C, mature (picture 3, top); cone D, mature (picture 3, bottom). Picture 4 depicts pollen grains of Florinites with ruptured trilete marks. 3 golden coprolites were identified in the cone B. A large golden coprolite (> 300) possibly from an insect was found in the matrix (picture 5). Plate 60A is a successive peel taken from the same coal ball as other plates labeled 60.
