anterior rim of the crown is gently convex and constitutes an
articular facet that, in life, connected to the posterior face of a tooth
located immediately in front. The posterior rim is generally straight,
and forms a shelf for an articulation with the anterior margin of
a tooth positioned immediately posterior in life. The crown overhangs
an anaulacorhizous root that varies in shape among the
different tooth types but is weakly bilobate or flat. A number of teeth
in the specimen do not preserve a root, but instead have a cancellous
dentine that fills the basal side of the enameloid ‘crown cap.’ Such
