Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 20A
Abstract
Cones A (picture 2) and B (picture 1) are mature cordaitean cones laden with golden and brown coprolites, both types deposited in strings (pictures 3, 4, 5 and 6). No coprolites were found in the matrix. Picture 8 shows a grain of Florinites with a ruptured trilete mark. Plate 20A is a successive peel taken from the same coal ball as other plates labeled 20.
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.
2 Mature Cones
Two cones filled with golden and brown coprolites.
Cone A contains 4 golden coprolites and 17 brown coprolites.
Cone B contains 24 golden coprolites and 1 brown coprolite.
Florinites grains have a ruptured trilite mark.
Mounted peels were made by William C. Darrah.
