Ostracod fauna, environmental trends and phases of the global Taghanic Biocrisis through time in the Peran-Perlora and Carranques cumulated sections. For stratigraphical column caption and bio- and chronostratigraphic correspondences, see Figure 2. A. Ostracod faunal succession and phases of the global Taghanic Biocrisis through the series: 1. decline of the diversity of the “ Givetian ” ostracod fauna; 2. occurrence of short-ranging opportunistic taxa; 3. interval of rare fauna; 4. renewal of the ostracod taxa with installation of the new “ Frasnian ” fauna. Possible equivalents of the transgressive pulses IIa-Tagh and IIa-Gen are indicated, as well as the Taghanic Biocrisis assumed interval (grey hatched part) and the Geneseo Bioevent (dark grey rectangle). B. Palaeoenvironmental reconstruction based on analyze of ostracod assemblages for each sample (black dots), crossed with information from lithology and other faunas (white dots: biostromal units; the dashed line indicates the general trend through time). All the ostracods collected through the series belong to the Eifelian Mega- Assemblage (see Casier 1987 b, 2008): Assemblage I is dominated by Eridostracina, Palaeocopina, Platycopina and is indicative of semi-restricted environments; Assemblage II is dominated by Podocopina (of which thick-shelled taxa) and is indicative of open-marine peri-reefal agitated environments; Assemblage III, showing well diversified Metacopina, Podocopina, Eridostracina, Palaeocopina, Platycopina and characterized by an increase of the proportion of Metacopina with depth coupled to a decrease of the Podocopina one, is indicative of open-marine deeper environments. Units M, N and O show disturbed environments (see text)." pageId="53" pageNumber="54">Fig. 5</figureCitation>

Large elongated carapace, subtrapezoidal to subhexagonal in lateral view, biconvex in dorsal view. Overlap of the larger LV over the RV very pronounced dorsally, otherwise slight at free margins of the carapace. Bow-shaped projection in ventral view. Hmax median; Lmax at 2/5 ventral; Wmax slightly ventral. Dorsal margin regularly convex in its middle part, becoming more convex towards anterior and posterior and then concave near anterior and posterior extremities of the carapace. Ventral margin convex, becoming more arched at its extremities. Dorsal and ventral margins converging both posteriorly and anteriorly. Anterior margin slightly concave in its dorsal part to the anterior end point about at mid-height, and, from this point, regularly convex in its ventral part. Anterior end forming an angle of about 110°. Posterior margin slightly concave in its dorsal part to the posterior end point (posterior Lmax point), and from this point, convex in its ventral part. Posterior end very sharp and forming an angle of about 85°. Anterior end of the carapace higher than the posterior one. Anterior part of the carapace higher than the posterior one. Surface smooth.
