'''''Lepidaspis serrata''''' ("serrated scaly shield") is an extinct [[heterostraci|heterostracan]] [[jawless fish]] from Early [[Devonian]] [[Canada]]. Its scientific name refers to the fact that the armor is composed of hundreds of tiny scales with serrated edges.

Although it is regarded as a heterostracan, its exact placement within Heterostraci is regarded as ''[[incertae sedis]]'', as the fact that it is currently impossible to discern where its dorsal and ventral plates (which are made up of a mosaic of the aforementioned tiny scales) end or begin.  Some experts regard it as being descended from the basal heterostracans of the [[Silurian]].
