Целью настоящей работы является анализ динамики видового разнообразия конодонтов в фаменско-серпуховское время.</p></sec><sec><title> Материалы и методы</title><p> Материалы и методы. На основе обобщения литературных данных и материалов автора создана база данных, включающая информацию о стратиграфическом распространении (с точностью до зоны) 389 видов и подвидов фаменско-серпуховских конодонтов. Информация о распространении видов заносилась в базу данных (https://1drv.ms/x/s!AvPFMTPLPc7T4nFU81CaO5UJ6nlw), по которой для каждого стратиграфического подразделения вычислялись следующие параметры: таксономическое разнообразие, количество появившихся видов, количество вымерших видов и коэффициент обновления фауны.</p></sec><sec><title>Результаты</title><p>Результаты. Выделено четыре цикла, разделенных минимумами разнообразия: два фаменских, турнейский и визейско-серпуховский. Абсолютный максимум разнообразия для рассматриваемого временного интервала отмечается в фазе marginifera (81 вид в ранней marginifera и 80 видов в поздней marginifera), а в позднефаменско-серпуховское время происходило снижение видового разнообразия.</p></sec><sec><title> Выводы</title><p> Выводы. За исключением двух массовых вымираний (фран-фаменского и девонско-каменноугольного), глобальные геологические события оказывали слабое влияние на разнообразие конодонтов. Переход от парникового к ледниковому климату в начале раннего карбона и связанное с ним изменение морских экосистем, вероятно, явились причинами последовательного снижения разнообразия в позднетурнейскосерпуховское время.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Subject</title><p>Subject. The article is aimed to evaluate of the conodont diversity dynamics at the species level in the Famennian – Serpukhovian interval.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The database compiled from the published and original data contains information on the stratigraphic ranges of 389 Famennian-Serpukhovian conodont species (<ext-link xlink:href="https://1drv.ms/x/s!AvPFMTPL" ext-link-type="uri">https://1drv.ms/x/s!AvPFMTPL</ext-link> Pc7T4nFU81CaO5UJ6nlw). Conodont zones compose the geochronological basis of the database. The conodont diversity, origination, extinction, and diversification were calculated. Dynamics of these parameters in the Late Devonian–Early Carboniferous was analyzed.</p></sec><sec><title>Results</title><p>Results. The Famennian-Serpukhovian conodonts demonstrate four cycles in the diversity: the early Famennian (triangularis-early postera zones), the late Famennian (late postera-praesulcata zones), the Tournaisian (sulcata-anchoralis zones), and the Visean-Serpukhovian (texanus-bollandensis zones). The cycles are separated by the low-diversity episodes. The highest diversity (80 species) is detected in the early and late marginifera zones (Famennian).</p></sec><sec><title>Conclusions</title><p>Conclusions. The successive decreasing in diversity comprises interval from the late Famennian through Serpukhovian. The global events gave little influence on the conodont diversity except for the Frasnian/Famennian (about 70% conodont species became extinct) and Devonian/Carboniferous extinction events. Conodont diversity demonstrates weak dependence form the global sea level fluctuations. The transition from the green-house to ice-house climate at the beginning of the Carboniferous and successive changes in the marine ecosystems are considered as main probable cause of the decline in conodont diversity in the late Tournaisian-Serpukhovian.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>конодонты</kwd><kwd>разнообразие</kwd><kwd>поздний девон</kwd><kwd>ранний карбон</kwd><kwd>глобальные события</kwd></kwd-group><kwd-group xml:lang="en"><kwd>conodonts</kwd><kwd>diversity</kwd><kwd>Late Devonian</kwd><kwd>Early Carboniferous</kwd><kwd>global events</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Аристов В.А.
