Figure 4. Micromorphological differences amongst the three major clades (XXI, XIX, XVII). The vertically oriented plates shown in each photo are septa. The projections along their upper margins are teeth, and those across their lateral faces are granules. Clade XXI (A-C) is distinguished by regular blocky teeth with pointed tips, and aligned granules. Clade XIX (D-F) is distinguished by irregular lobate or bulbous teeth with elliptical tooth bases, and rounded granules enveloped by extensive thickening deposits. Clade XVII (G-I) is distinguished by irregular multiaxial teeth with circular bases, and irregular scattered granules.
