Fig. 14. Palmatolepids (A–H, J–L) and ancyrognathids (I) from Middle Frasnian of the Holy Cross Mountains and Dębnik; SEM micrographs. A–C. Palmatolepis sp. A. A. GIUS 4−3428−6, sample KPK F1, Kowala. B, C. GIUS 4−3429−11 (B) and GIUS 4−3431−3 (C), sample Kt−V 128, Kostomłoty−Mogiłki. All specimens are characterized by the platform outline transitional between Palmatolepis transitans and Palmatolepis hassi. They possess slightly curved carina and laterally directed outer lobe demarcated by weak to moderate sinuses. The platform is nearly flat, poorly ornamented or covered with fine nodes. Some specimens (C) show affinities to Palmatolepis gutta Kuzmin, 1998, however, the wider platform of Palmatolepis sp. A has more pronounced, triangular outer lobe. From Palmatolepis punctata they differ in uniform and more delicate ornamentation and a sinusous course of carina, however the posterior carina is not as much curved inward as in Palmatolepis hassi. D, J. Palmatolepis hassi Müller and Müller, 1957 (sensu Ziegler and Sandberg, 1990). D. GIUS 4−3431−4, sample WId−W 62, Wietrznia Id−W. J. GIUS 4−3432−1, sample Kt−V 154, Kostomłoty−Mogiłki. E. Palmatolepis sp., GIUS 4−3428−7, sample WIe 233/2, Wietrznia Ie, specimen displaying similarity to Pa. maximovae Kuzmin, 1998 with its deep sinus in posterior part of the platform. F. Palmatolepis aff. triquetra Kuzmin, 1998, GIUS 4−3432−2, sample KPK F9, Kowala. G. Palmatolepis plana Ziegler and Sandberg, 1990, GIUS 4−3429−12, sample WIe 233/2, Wietrznia Ie. H. Palmatolepis aff. Pa. proversa Ziegler, 1958, GIUS 4−3432−3, sample WId−W62, Wietrznia Id−W. I. Ancyrognathus sp. A, GIUS 4−3432−4, sample Sl 16, Śluchowice. The Pa elements of the specimens are robust, covered irregulary with nodes or short transverse ridges on marginal sides; posterior carina is gently curved outwardly while secondary carina is slightly directed anteriorly; pit is large, elongated and diamond−shaped. K. Palmatolepis punctata (Hinde, 1879), GIUS 4−3428−8, sample Kt−V 128, Kostomłoty−Mogiłki. L. Palmatolepis bohemica Klapper and Foster, 1993, GIUS 4−3430−3, sample Kt−V 128, Kostomłoty−Mogiłki.
