''[[Brindabellaspis]]'' ("[[Brindabella Ranges|Brindabella's]] shield") was a long-snouted placoderm from the [[Early Devonian]]. When it was first discovered in 1980, it was originally regarded as a [[weejasperaspid]] [[acanthothoracid]] due to anatomical similarities with the other species found at the same locality. According to [[Philippe Janvier]], anatomical similarities in the brain of ''[[Brindabellaspis stensioi]]'' and the brain of a [[jawless fish]] suggest it is a basal placoderm closest to the ancestral placoderm. Various Early to Middle Devonian placoderm ''[[incertae sedis]]'' have also been inserted in the order.
