Herasmius is an extinct genus of heterosteid placoderm known from remains discovered in Norway.
Description
This genus is known from freshwater deposits of the early Eifelian-aged Verdalen member of the Stjørdalen formation in the Wood Bay series, Spitzbergen, Norway. In addition to being smaller than Heterosteus, Herasmius differs by having a comparatively broader, shorter skull.[1]
