摘要

The osteology of Caprosimilis carpathicus gen. et sp. nov., from the Early Oligocene Menilite beds of the Outer Carpathians, Poland, is described. This taxon possesses a unique combination of features that supports its recognition as a new genus of the superorder Acanthopterygii. It is characterized by: deep body, posterior part of frontals ornamented with curving ridges and spines, eight branchiostegal rays, 24 vertebrae (10 abdominal), ossified ribs present on 4th to loth abdominal vertebrae, nine spines and 21 soft rays in dorsal fin, four spines and 18 soft rays in anal fin, three anal-fin pterygiophores in first interhaemal space (between haemal spines of first and second caudal vertebrae), three supernumerary spines on first radial of anal fin. Caprosimilis carpathicus gen. et sp. nov. is compared with extant genera of Caproidae (Antigoniu and Capros), Zeiformes (Owns and Oreosoma) and Tetraodontiformes (Parahollardia), and with the Early Eocene genera Protozeus, Acanthonemus and Zorzinichthys to access its phylogenetic position. A phylogenetic analysis indicates that C. carpathicus gen. et sp. nov. is a close relative of the Caproidae.
