Erikaspis Explained

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.^{[1] [2]}

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