A thin concentric ring is present at the tooth base on some specimens. Teeth largely consist of smooth enameloid crowns, with large open basal pulp cavity. Pulp cavity flat to weakly concave. Tooth plates with sub-oval occlusal outline, flat to dome-shaped in profile, consisting of vertically stacked rows of teeth. Largest teeth positioned medially within tooth plate; tooth diameter decreases laterally. Tooth stacking very tight, little interstitial bone.</paragraph>
