Cone A (picture 1, left) and B (picture 1, right) are mature cordaitean cones containing no coprolites.

Cone maturity is as follows- cone A, mature (picture 1); cone B, taphonomically degraded (picture 2); cone C, basal section (picture 3); cone D, mature (picture 4), cone E, taphonomically degraded (picture 5), cone F, ...

Cone maturity is as follows- cone A, immature (picture 1); cone B, basal section (picture 2); cone C, taphonomically degraded (picture 3). Plate 78A is a successive peel taken from the same coal ball as other plates labeled 78.
