Originally the fish was described by Agassiz in 1833 under the name Palaeoniscus vratislaviensis. Taxonomy from Štamberg 2021. Diagnosis of Paramblypterus vratislaviensis from Štamberg 2021, p. 77:”. Small fish usually ranging from 100 to 120 mm, exceptionally to 150 mm. The frontal is 3.5 times longer than wide and 2.5 times longer than the length of the parietal. The anterior margin of the frontal is concave medially, interfrontal suture only slightly undulated and without folds, the sculpture on the frontal consists of ridges parallel with the posterior margin of the bone. The dermosphenotic is narrow, elongated anteroposteriorly. The dermopterotic, with lateral process but without posterior process, is narrower anteriorly than posteriorly. The infraorbital superior, dermosphenotic and supraorbital anterior form the dorsal edge of the orbit. The maxilla has a short and high maxillary plate which is convex dorsally, the length/height ratio of the maxillary plate is 1 or less than 1. The operculum is oblong in shape, 1.4 times deeper than it is long. The scales on the anterior part of the body bear fine ridges extending posteriorly to the denticles. Denticulation decreases on the scales in the posterior direction and the last denticulate scale appears in the 13th scale row. A field of small scales occurs along the base of the anal and dorsal fins.” Line drawing from Štamberg 2021, p. 82: Paramblypterus vratislaviensis (Agassiz, 1833). a: restoration of the body in lateral view, scale bar 10 mm.

Taxonomy from Fossilworks.org. Emended diagnosis from Dietze 2003, p. 942: "Little ornamentation of parietals, postparietals, extrascapulars, posttemporals, dermosphenotics, supratemporals and supracleithra. Parietals with lateral process. One or two medial extrascapular(s). Additional lateral extrascapulars do not contact opercle. Rostral tapering anteriorly. Sclerotic bones absent. Five `suborbital' bones. Maxillary plate deep. One to three dermohyal bones. `Spiracular' rounded. Eight branchiostegal rays. D-values of scales higher than 2:0: 42 6 2 scale rows along lateral line. Area of serrated scales on body not tapering towards anal fin. Ornamentation of scales fairly prominent." Line drawing from Dietze 2003, p. 942: Identified by oilshale.
