Figure 2a. Palynomorph profile of 20 common taxa from the middle seam and overlying marine argillaceous sandstone. A stratigraphic section of the middle seam appears to the left with seam thickness measured in cm from the top of the seam (0). Yancey (this volume) gives a detailed, complete stratigraphic section of the spillway outcrop. A layer dominated by fern spores, Cicatricosisporites and Laevigatosporites, occurs at the base of the seam. Momipites coryloides predominates throughout most of the rest of the seam; Cupuliferoipollenites spp. and M. coryloides predominate in the burrowed upper 10 cm of this seam.

Figure 2b. Palynomorph profile of 20 common grains from the middle seam. A stratigraphic section of the lower seam appears to the left with seam thickness measured in cm from the top of the seam (0). A layer dominated by fern spores, Cicatricosisporites and Laevigatosporites, occurs at the base of the seam. Momipites coryloides predominates throughout most of the rest of the seam; however Cupuliferoipollenites spp. replaces M. coryloides in the burrowed upper 10 cm of this seam.

Figure 2c. Palynomorph profile of 20 common taxa from a replicate sample of the upper burrowed layer, the variable claystone and the underlying lignite of the middle seam. Momipites coryloides predominates throughout most of the rest of the seam; however Cupuliferoipollenites spp. replaces M. coryloides in the burrowed upper 10 cm of this seam.

Figure 2d. Palynomorph profile of 20 common taxa from a replicate sample of the upper burrowed layer, the variable claystone and the underlying lignite of the middle seam. Momipites coryloides predominates in most of this samples; however Cupuliferoipollenites spp. replaces M. coryloides in the burrowed upper 10 cm of this seam.
