本文记述了基生辐鳍类一新种，哥哥沙丁鱼Gogosardina coatesi gen.et sp.nov.描述于西澳大利亚坎宁盆地上泥盆统戈戈组。新的分类群是已知的四个准备标本，显示了该地区的脊椎动物化石的典型例外保存。Gogosardina gen. nov.拥有一系列的四个小postrostrals，没有surangular和一个非常纤细的身体覆盖着超过140个垂直行的非常小的鳞片，所有都与独立的水平ganoine脊。其中一个标本含有牙形石元素，卡在鳃弓之间，表明饮食习惯和可能的死亡原因。
A new basal actinopterygian, Gogosardina coatesi gen. et sp. nov., is described from the Upper Devonian Gogo Formation of the Canning Basin, Western Australia. The new taxon is known from four prepared specimens that display the typical exceptional preservation of fossil vertebrates from the region. Gogosardina gen. nov. possesses a series of four small postrostrals, no surangular and a highly gracile body covered with over 140 vertical rows of very small scales, all ornamented with separate horizontal ganoine ridges. One specimen contains conodont elements lodged among the branchial arches, indicating dietary habits and a possible cause of death.
