Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 22C
Abstract
Cone maturity is as follows- cone A, immature (picture 1); cone B, basal section (picture 2); cone C, immature (picture 3); cone D, immature (picture 4); cone E, basal section (picture 5); cone F, immature (picture 6); cone G, basal section (picture 7). Cone A, B, C, F and F contained brown coprolites within their cone scales. Cone D contained a single golden coprolite. Plate 22C is a successive peel taken from the same coal ball as other plates labeled 22.
Description
These images were used in the research for a master's thesis from the Texas A&M University Dept. of Geology and Geophysics (Date of submission: May 2020).Images were taken from slides on loan from the Harvard Paleobotanical Herbarium.

3 basal sections
Cone A contained 16 brown coprolites.
Cone B and F contained 1 brown coprolites.
Cone C contained 10 brown coprolites.
