LOWER DEVONIAN MICROVERTEBRATES FROM THE POINT HIBBS FORMATION, TASMANIA

Palaeozoic microvertebrate remains are documented from the Point Hibbs Formation, Point Hibbs, western Tasmania. They comprise scales, teeth and ornamented dermal bone from acanthodians ''Nostolepis'' guangxien sis, Nostolepis spp., Gomphonchus? bogongensis, Trundlelepis cervicost ulata and Watsonacanthus? sp., onychodontiform sarcopterygians, and fo ur types of placoderms. The microvertebrate fauna supports a Lower Dev onian (Pragian) age for the deposit, when compared with other eastern Australian occurrences of the these taxa.
