Portentosoceros , the new genus for the Neogene fish Pentaceros sakhaliniсus Gretchina (Perciformes, Percoidei) from the western Pacific and its taxonomic position
The Miocene fossil fish † Pentaceros sakhaliniсus Gretchina, 1975, (Perciformes, Pentacerotidae) is redescribed based on the holotype and numerous additional materials collected on Sakhalin Island (western Pacific, Russian Far East) at the end of the 20th century. The general appearance and body pro...
