 All seven maxillary teeth are molariform, though they vary greatly in size; the first three and the last two are much smaller than the two middle ones, only about half the size overall.All the maxillary teeth have one deep root, oval in cross-section, and there is a slight constriction between this and the crown of the teeth, which are flattened obliquely to produce a spatulate shape.The outer surfaces of the maxillary teeth are smooth and bear a few grooves, whereas the inner surfaces are covered in denticles that grow smaller towards the tip of each tooth.
