Five incomplete skeletons of fishes of the extinct monotypic family Polymerichthyidae (Aulopiformes: Alepisauroidei) from the Paleogene and Neogene of Sakhalin Island, Russia, are identified as Polymerichthys sp., described in detail, and compared with known representatives of the family. The results of this study suggest that polymerichthyids were characterized by a prolonged rostrum, behind which the upper jaw symphysis was placed; by an anal fin without spinules, contrary to what was assumed… 
A Miocene pearleye, Benthalbella praecessor, sp. nov. (Teleostei, Aulopiformes), from Sakhalin Island, Russia: the first known skeletal record for the family Scopelarchidae
Paleoecological considerations suggest that Benthalbella praecessor was a deep-sea fish that inhabited the cold-temperate waters of the northwestern Pacific about 14 Ma, and appears to be closely related to the extant B. dentata.

Abstract. A fossil palatine of an alepisauroid fish collected from the middle Miocene Yokoo Formation in Nagano Prefecture, central Japan is described as Omosudis sp. Although the palatine is only a
Fossil impression of a nephtyid polychaete (Polychaeta: Nephtyidae) in the Miocene sediments of Sakhalin (NW Pacific)
During the expedition of the Zoological Institute of the Russian Academy of Sciences (ZIN RAS) in 1998, a fossil impression of a polychaete worm belonging to the family Nephtyidae Grube, 1850,
Osteology of the Southern Ocean daggertooth (Anotopterus vorax) and status of the Anotopterus genus in the Aulopiformes order
Cladistic analysis has been performed with the finding that the Southern Ocean daggertooth is united with the A. pharao and the Polymerichthys fossil genus into one clade, which takes an intermediate status between the representatives of the Alepisauridae and Paralepididae families.
Fossil impressions of pectinariid tubes (Polychaeta) in Miocene sediments of the Sakhalin Island
The fossil impressions of tubes belonging to the bristle worms of the family Pectinariidae and probably the genus Pectinaria Savigny, 1818 was found at the coastal cliffs of the Tartar Strait
Fossil impression of a nephtyid polychaete ( Polychaeta : Nephtyidae ) in the Miocene sediments of Sakhalin ( NW Pacific )
Based on the analysis of the jaw shape, it is concluded that the nephtyid impression may belong to the genus Nephtys Cuvier 1817 or the genus Aglaophamus Kinberg, 1865.


Fossil bristlemouth Cyclothone mukhachevae sp. nov. (Stomiiformes: Gonostomatidae) from the Neogene of western Sakhalin, Russia
The first Russian record of fossil bristlemouth from the Middle-Late Miocene of Sakhalin Island (Kurasi Formation) is reported and described as a new species, Cyclothone mukhachevae (Pisces:
Paraulopidae and Paraulopus, a new family and genus of aulopiform fishes with revised relationships within the order
Paraulopus clearly belongs in Aulopiformes owing to an enlarged uncinate process on the second epibranchial, the absence of a swimbladder, and fusion of the medial processes of the pelvic girdle, but the phylogenetic position of Paraulopus is defined by a cladistic analysis of 101 morphological characters, in 21 genera of Aulipiformes.

Attachment modes 2, 3, and 4 are each associated with a major evolutionary lineage within the Teleostei and the degree to which paedomorphosis has been a factor in teleostean evolution is discussed.
