Young, Gavin C., 2003, A new species of Atlantidosteus Lelièvre, 1984 (Placodermi, Arthrodira, Brachythoraci) from the Middle Devonian of the Broken River area (Queensland, Australia), Geodiversitas 25 (4), pp. 681-694 : 684

Genus Atlantidosteus Lelièvre, 1984

REMARKS

Lelièvre (1984a) defined his new genus on the following features of the SO plate: suborbital lamina strongly incurved in a medial direction; high postorbital lamina; ornamentation of very small tubercles. The unusual shape of this new example of the SO plate closely resembles that of the type species, in having a high postorbital lamina with a curved dorsal margin, an unornamented mesially directed suborbital lamina, and a distinctive sensory groove pattern.
