Comparison of scales between Libys callolepis sp. nov. and some other Latimeriidae. A Libys callolepis sp. nov. (holotype, NMBE 5034072). Scales of the flank below the neural arches between the basal plates of the anterior and posterior dorsal fin. B Libys polypterus (‘L. superbus’) (BSM AS I 801a). Scales of the flank located between the neural arches and the basal plate of the second dorsal fin. C Undina penicillata (BSM 1870 XIV 22). Scales of the middle flank located on the neural arches below the basal plate of the second dorsal fin. D Trachymetopon (‘Macropoma’) substriolatum (holotype, SMC J27415) from the Kimmeridgian of Cottenham, Cambridgeshire. Scales of the middle flank. It is worth noting that this species was first attributed by Huxley (1866) to the genus Macropoma and latter to Coccoderma by Reis (1888). Forey (1998) kept this species within Coccoderma, but remarked that it shows affinities with Holophagus. Recently, Cavin et al. (2021a) attributed this specimen to the genus of Trachymetopon regarding, among other characteristics, the coarse ornamentation on the dermal bones
