). Small denticles are present along the upper edge of the enameled surface. Unlike adult ceratopsian teeth, these have a single unbifurcated root, a condition Hatcher and others (1907) noted for young incipient teeth. It is doubtful that these small teeth are incipient teeth of an adult, because they are well developed and have a long root, which is unlike the short, thin-walled, open root of the adult. It is probable that the root became bifurcated as the animal matured. Because there are two genera of ceratopsians (
