Проведен анализ палеогеографического распространения папоротников рода Coniopteris на территории Европы, Центральной Азии и Сибири на протяжении семи веков (с геттангского по батский) ранне- и среднеюрской эпох. Установлено, что в геттангском веке род Coniopteris имел широкое распространение от Европы до Южной Сибири.
