Abstract
The vertebrate microfauna from the Early Devonian Buchan Group in northeastern Victoria is dominated by remains of acanthodians and placoderms, with osteichthyans less common, and chondrichthyans and thelodonts rare. Acanthodian remains include scales of Nostolepoides platymarginata, "No,stolepis" guangxiensis, Gomphonchus? bogongensis, scales similar to those of Cheiracanthoides comptus and C. wangi, and possible Rhadznacanthus scales. Scales of artluodires Goodradigbeeon and Buchano,steus are the most abundant placoderm remains; placoderm plate fragments are attributed to Buchanosteus and Murrindalaspis Osteichthyan remains include a scale of the actinopterygian Ligulalepis toombsi, and onychodont scales and teeth. Taxa previously undescribed from Buchan ar•e acanthodians "Nostolepis" guangxiensis, Cheiracanthoides sp. cf C wangi and Rhadinacanthus, chondrichthyan Ohiolepis sp, and osteichthyan Ligulalepis toombsi
