Errivaspis is an extinct genus of pteraspid heterostracan agnathan vertebrate known from fossils at the Wayne Hereford Quarry, of Early Devonian England, and of Podolia, Early Devonian Ukraine. It was originally described by Dr. Errol Ivor White as one of five form-variants of Pteraspis rostrata, i.e., "Pteraspis rostrata var. waynesis.[1] In 1984, Alain Blieck moved var. waynesis into its own genus, Errivaspis, which he named after Dr. White.[1][2] Other later researchers would then mistakenly assume that Blieck synonymized the entire genus of Pteraspis into Errivaspis.
