    On the significance of tuskless specimens of Dicynodon grimbeeki Broom
    (Bernard Price Institute for Palaeontological Research, 1958-06-01) Barry, T. H.
    It has hitherto been accepted that Dicynodon grimbeeki, a species of the extinct Karroo mammal-like reptiles, possesses canine tusks in the males only. This theory is discussed in detail. An investigation is also made of the extent of the influence of sexual dimorphism on the dentition of extant forms. It is concluded that the evidence against the theory that the males only are tusked is such that it cannot be accepted.
