Murrindalaspis

Extinct genus of fishes

Murrindalaspis is an extinct genus of acanthothoracid placoderm found in the McLarty Member of the Murrindal Limestone, of the Early Devonian-aged Buchan Group in eastern Victoria, Australia. Murrindalaspis differs from other acanthothoracids by having a dorsal plate with a large, blade-like flattened, recurved crest emanating from the medial line, and no ventral keel. So far, the genus is known only from dorsal plates and ossified eyeballs. The genus differs from the closely related Weejasperaspis in that the dorsal crest of the latter is shorter, and triangular-shaped.
