Remigolepis is a genus of antiarch placoderm from Devonian. Species are described from East Greenland, China, Tula region of Russia, Kyrgyzstan, Australia, Belgium. In addition, indeterminate remains are known from Old Red Sandstone in Scotland. ^{[1] [2] [3]}

Description

Slab from Mandagery Sandstone including many specimens of R. walkeri and Bothriolepis yeungae

Remigolepis is a member of Asterolepidoidei, and it is considered as a sister taxon of Pambulaspis , while next most closely related genus is Asterolepis. R. walkeri from Mandagery Sandstone, Canowindra, New South Wales is known from over 1,000 specimens which shield length ranging between 7.8–18.5 centimetres (3.1–7.3 in). ^[1] While other Late Devonian antiarchs like Bothriolepis and Asterolepis lacked pelvic fins and had single dorsal fin, Remigolepis lacked both of pelvic and dorsal fins. ^{[1] [4]}
