Wuttagoonaspidae

Wuttagoonaspidae is a family of extinct primitive arthrodire placoderm fishes from Early Devonian China and Middle Devonian Australia. It contains two genera, Wuttagoonaspis and Yiminaspis, some of the more basal members of the order Arthrodira, as shown in the cladogram below:^[1]
