Givetian ostracods of the Candás Formation (Asturias, North-western Spain): taxonomy, stratigraphy, palaeoecology, relationship to global events and palaeogeographical implications Author Maillet, Sebastien Author Milhau, Bruno Author Vreulx, Michel Author Posada, Luis-Carlos Sánchez De text Zootaxa 2016 4068 1 1 78 journal article 10.11646/zootaxa.4068.1.1 b9c1e3a3-e591-4b34-9f30-d6d88a230673 1175-5326 270644 80E89736-33F2-4FF5-9B01-8B7239407875 Cryptophyllus sp. P2 (Pl. II: Fig. 13) ? 1964 Cryptophyllus sp. 3; Magne: pl. 21, figs. 94–96. 2013 Cryptophyllus sp. P2; Maillet: 98, pl. XII, fig. 22. Material. 21 specimens (4 C, 10 V , 7 F). Description. Medium-sized elongated carapace, asymmetric and sub-oval in lateral view. Moult retention ostracod with at least 4 large exuviae. Almost straight dorsal margin. Rounded umbo prominent over dorsal margin at 2/5 anterior. Anterior cardinal angle of about 160°. Posterior one of about 150°. Free margins of the carapace well rounded, more convex in anterior and posterior parts. Anterior part of the carapace slightly higher than the posterior one. Hmax at 2/5 anterior; Lmax at 1/3 dorsal; Wmax clearly dorsal and slightly anterior (umbo). Overlap of the valves unknown. Surface smooth. Discussion. With their elongated carapace, these specimens maybe compared with Cryptophyllus sp. 3 of Magne (1964), from the Middle and Upper Givetian of the Ardenne and the Boulonnais. In our specimens, the umbo is however less prominent over the dorsal margin. The bad preservation of exuviae makes any species identification difficult. Occurrence. Middle Givetian (Candás Fm, mbs B and C), Asturias (Peran-Perlora section).
