Erikaspis

Erikaspis is an extinct monospecific genus of arthrodire placoderm fish found in Lochkovian-Pragian (Lower Devonian) deposits of Podolia, Western Ukraine. The type species Erikaspis zychi was originally described in 1945 by Erik Stensiö based on a partial skull-roof, and was named Kujdanowiaspis zychi. In 2007, it was subsequently reassigned to the newly named genus Erikaspis, based on significant differences from Kujdanowiaspis.

It is one of the more basal members of the order Arthrodira, as shown in the cladogram below:
