The Victorian naturalist . The unanswered ques-tions are discussed as well as the rela-tively firm conclusions, for in theformer lie the most fertile ground forfuture research. Batesford In October 1975, Mr Greg Sack ofHawthorn, Victoria, when on a visit tothe Batesford Quarry of AustraliaPortland Cement Ltd, near Geelong,discovered the left and right mandiblesof a Zygomaturus sp, a member of thefamily Diprotodontidae, NationalMuseum of Victoria P42530. Bothmandibles had M2-4 preserved, unfor-tunately in an extremely advancedstate of wear preventing a more pre-cise identification. Measurements in-dicate that this individual is as large asthe largest available specimens of thePleistocene Zygomaturus trilobus andthe Pliocene Zygomaturus keani, thelargest of the recognized species in thegenus. Where did the enclosing matrix comefrom? During the course of quarrying acti-vity, the block of matrix in which thespecimen occurred was moved at least100 metres to the place it was foundon the quarry floor by Mr Sack. That. Fig. 2.
