Prosolenostomus lessinii Blot 1981 Eocene Monte Bolca near Verona Italy The species of the family Syngnathidae belong to the order Syngnathiformes. The name "Syngnathiformes" means "conjoined-jaws". Syngnathiformes is an order of ray-finned fishes that includes among others false pipefishes, ghost pipefishes and tubemouth fishes (Solenostomidae), pipefishes and seahorses (Syngnathidae), razorfishes (Centriscidae), trumpetfishes (Aulostomidae) and cornetfishes (Fistulariidae). Fishes of this order have elongate, narrow, bodies surrounded by a series of bony rings, and small, tubular mouths. The tubular mouth shows that these members of the Syngnathiformes fed on small Crustaceans and such, much as their modern-day relatives Seahorses and Pipefishes. The family Syngnathidae includes the pipefishes and seahorses as well as the leafy and weedy sea dragons. The species of the subfamily Solenostomidae (false pipefishes) have elongated, thin, snake-like bodies with a highly modified skeleton formed into armored plating. The head is elongate with a long and slender, tubular snout; the mouth being small and toothless. The dorsal fin is the main part of locomotion. They are very weak swimmers in open water, moving slowly by means of rapid movements of the dorsal fin. In many respects, they are similar to the pipefishes (Syngnathidae), but can be distinguished by the presence of pelvic fins, a prominent, spiny, dorsal fin and star-shaped plates on the skin. The species of the subfamily Solenostomidae are abundant on coasts of the tropical and temperate zones. Most species of pipefish are usually no longer than 15 cm in length and generally inhabit sheltered areas in coral reefs, seagrass beds and sandy lagoons. -
Pesciarichthys baldwinae Sorbini & Tyler, 1998 was redescribed in 2012 by Bannikov & Tyler and the new genus Frigosorbinia established. Taxonomy from Fossilworks.org. Diagnosis from Bannikov and Tyler 1998, p. 27:" Body a deep ovoid in shape; head relatively small. Mouth small; teeth relatively small and lobate. Five branchiostegal rays. Vertebrae 22 (9 + 13); haemal spines of first two caudal vertebrae slender, oriented posteroventrally, and not in close proximity in their middle regions. Tenth caudal vertebra with elongate slender neural and haemal spines. One supraneural. Dorsal fin with eight spines and 23 soft rays. Both first dorsal-fin spine and first anal-fin spine protrude to exterior. Anal fin with three spines and 21 soft rays. Tenth interneural space with two basal pterygiophores; 11th space with one basal pterygiophore. First interhaemal space with two basal pterygiophores. Pelvic bone with relatively shallow subpelvic keel (12% of pelvic length). Scales very small over most of body and head. Each scale consists of a small basal plate with upright spinules. Larger rounded scale plates scattered posteriorly on body in region of caudal peduncle; these larger scales are densely spaced together and slightly more than twice the size of the small body scales elsewhere. Caudal peduncle with three moderate, fixed, keeled bony scutes." Line drawing from Sorbini & Tyler 1998, p. 25 : Identified by oilshale using Sorbini & Tyler 1998.
