Dapedium stollorum THIES & HAUFF 2011 Early Jurassic Posidonia shale Holzmaden Germany Length 23cm Lit.: D. Thies and B. Hauff: A new species of Dapedium LEACH, 1822 (Actinopterygii, Neopterygii, Semionotiformes) from the Early Jurassic of South Germany. Palaeodiversity 4: 185–221; Stuttgart 30 December 2011. -
Taxonomy from Thies & Waschkewitz 2015. Formerly identified as D. punctatum. Quote from Thies et Hauff, 2011: "Specimens of Dapedium from the Posidonia Shale identified as D. punctatum by QUENSTEDT (1858) were already suspected of not being conspecific with D. punctatum AGASSIZ, 1835 from the Lower Liassic (Sinemurian) of England by WAGNER as early as 1860." Diagnosis from Thies & Hauff 2011, p. 188: "Body ellipsoidal to circular in outline, rostral and ventral borders of the operculum forming an obtuse angle of 100° to 120°, caudal margin of scales serrated, anterior scales behind the operculum of the second to fourth vertical row with a length/height ratio ranging between 0.29 and 0.32, marginal teeth unicuspid."
