1937 Trans. Amer. Philos. Soc. 30 301 No evidence of replacement of the true molars has been seen, nor of a pre-lacteal series.

1968 Arch. Oral Biol. 13 171 (title) The early development of the incisor teeth of Setonix brachyurus (Macropodidae: Marsupialia) with special reference to the prelacteal teeth.
