Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 01(2019) Lakeram, ScottA single immature cordaitean cone containing no pollen.Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 02(2019) Lakeram, ScottA pollen mass located in the center of a mature cordaitean cone (picture 1), 2 brown coprolites were identified in the matrix with one displayings possible bite marks (picture 2 and 3).Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 03(2019) Lakeram, ScottA mature cordaitean cone (picture 6) yeilding 6 golden coprolites, four of which are deposited in a string formation (picture 1). A single small golden coprolite was located in the matrix (picture 3). Pictures 2 and 4 were taken under crossed polarized light showing intact pollen grains having no change in birefringence.Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 04(2019) Lakeram, ScottA mature cordaitean cone (picture 1) containing 41 golden coprolites desposited throughout the cone. Coprolites are primiarly composed of cuticle and highly macerated pollen grains of Florinites (picture 2 and 3).Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 05(2019) Lakeram, ScottCones A (picture 3) and B (picture 4) are mature cordaitean cones containing large pollen masses (picture 1 and 2).Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 06(2019) Lakeram, ScottA single immature cordaitean cone containing no pollen.Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 07(2019) Lakeram, ScottA single immature cordaitean cone containing no pollen.Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 08A(2019) Lakeram, ScottA string of 3 golden coprolites composed of mascerated Florinites near cone A (picture 1 and 3), both cone A (picture 2) and cone B (picture 4) are mature. A pollen mass can be found in the matrix above the coprolite string (picture 3).Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 08B(2019) Lakeram, ScottA large oblong coprolite near cone A picture 1, possibly originating from an insect. both cone A (picture 1) and cone B (picture 2) are mature. Picture 3 displays pollen originating from Cordaitina sp. in ruptured pollen sacks from cone A. Plate 8B is a successive peel taken from the same coal ball as plate 8A.Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 09(2019) Lakeram, ScottA mature cordaitean cone (left) and basal section (right).Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 10(2019) Lakeram, ScottA single immature cordaitean cone containing no pollen.Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 11(2019) Lakeram, ScottA mature cordaitean cone (picture 1) containing 10 small golden coprolites (picture 2). A large oblong golden and a brown coprolite coprolite possibly produced by an insect is located in the matrix.Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 12(2019) Lakeram, ScottA mature cordaitean cone (picture 4) containing Cordaitina sp. and 2 golden coprolites within its cone scales (picture 3). A large brown coprolite can be identified in the matrix to the left of the cone (picture 4). Picture 2 was taken under crossed polarized light showing intact pollen grains having no change in birefringence.Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 13(2019) Lakeram, ScottA mature a cordaitean cone (picture 4) filled with Florinites pollen grains and 3 golden coprolites (picture 1, 2 and 3).Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 14(2019) Lakeram, ScottA taphonomically degraded cone that is unidentifiable.Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 15(2019) Lakeram, ScottA mature cordaitean cone (picture 1) with a brown coprolite in the matrix (picture 2).Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 16(2019) Lakeram, ScottA mature cordaitean cone with ruptured pollen sacks.Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 17(2019) Lakeram, ScottA mature cordaitean cone with pollen clusters between the cone scales (picture 1). Picture 2 shows the ruptured trilete mark of pollen grains from Florinites.Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 18(2019) Lakeram, ScottA mature cordaitean cone (picture 1) conatining 13 golden coprolites. Coprolites are ovoid to oblong in shape (picture 2, 3 and 4).Item Cordaitean Predation Photos 2019: Mounted Peels, Harvard Collection. Plate 19A(2019) Lakeram, ScottA mature cordaitean cone containing pollen grains of Florinites. Plate 19A is a successive peel taken from the same coal ball as other plates labeled 19.
