Comments

Probably Propercarina cf. rebeli Pauca, 1929.

Alternative name: Palimphyes cf. rebeli (Pauca, 1929).

Taxonomy according to Fossilworks.org.

Diagnosis for the genus Propercarina according to Prikryl et al., 2014, p. 693: “Emended diagnosis (according to Pauca, 1929, 1934 and Bannikov, 1995, 2010, modified): Body elongated. Dorsal and ventral edges of body are almost parallel and they run alongside the axis of the vertebral column; the body is covered by small cycloid scales; the lateral line is parallel to the dorsal edge of the body and runs just dorsal to the vertebral column; massive but short preorbital area (snout); mouth gap is moderate; jaws possess teeth; ventral edge of the preopercle smooth; the postcleithrum is massive and long (almost reaching the ventral profile of body); three predorsals; two separated dorsal fins (first with six to nine spines; second with one spine and numerous posteriorly shortened soft rays); the dorsal fins are separated by about 5 or 6 ray-less interneurals; anal fin with two short spines and numerous soft rays; anal-fin rays more numerous than soft dorsal-fin rays; pectoral fins are relatively short and situated just under the level of the vertebral column; pelvic fins with a spine and 5 rays, located under pectoral fins, present in adults; caudal fin is moderately long and forked; 35–36 rectangular vertebrae with the posterior abdominal ones bearing long parapophyses with associated thin and long ribs.”
