A new placoderm fish of uncertain affinity from the Early-Middle Devonian Hatchery Creek succession at Wee Jasper, New South Wales

A new genus and species of placoderm (Edgellaspis gorteri) has a parallel-sided skull including a deep orbital notch, a large crown-shaped nuchal plate reaching forward past the level of the orbits to contact the pineal plate, and three pairs of sensory grooves meeting at a central point on the nuch...
