FAMENNIAN CONODONTS FROM KAL-E-SARDAR SECTION, EASTERN TABAS, CENTRAL IRAN

Abstract

<p class="abstract-testo">Sixty-three conodont species and subspecies from the Kal-e-Sardar section indicate that the strata span early to late Famennian. Contrary to most of the sections measured in the Shishtu Formation, the icriodid-polygnathid biofacies is restricted to the lower part of Kal-e-Sardar Famennian succession. Palmatolepid and bispathodid-dominated  biofacies in the middle and upper part of section represent a deep shelf to mid-continental slope marine environment. The currently accepted ranges of <em>P. tichonovitchi, P. tenellus</em> and <em>P. inconcinnus</em> are early Famennian, late Frasnian-early Famennian, and early to middle Famennian, respectively, together with middle to late Famennian for <em>P. nodoundatus.</em> Two new species, <em>Polygnathus sardarensis</em> and <em>P. yazdii,</em> are proposed.</p><p class="abstract-testo"> </p>
