摘要

在位于伊朗南部Zagros山脉的Kuh-e Gadvan和Banesh剖面的下白垩统矿床(Gadvan和Dariyan组)中发现了两种属于Heteraster Orbigny, 1853年的spatanoid棘球类。Heteraster couloni (Agassiz, 1839)在Barremian和Heteraster delgadoi (Loriol, 1884)在伊朗Aptian-Albian晚期得到证实。在伊朗发现的Heteraster和其他spatanoid类棘虫显示了早白垩世特提斯南缘和北缘的明显区别。

Early Cretaceous Toxasterid Echinoid Heteraster from the high Zagros basin, south of Iran

Two species of spatangoid echinoid belonging to Heteraster Orbigny, 1853, are described from Lower Cretaceous deposits (Gadvan and Dariyan formations) at the Kuh-e Gadvan and Banesh sections situated in Zagros Mountains, south of Iran. Heteraster couloni (Agassiz, 1839) is confirmed in the Barremian and Heteraster delgadoi (Loriol, 1884) in the late Aptian-Albian of Iran. The occurrences of Heteraster and other spatangoid echinoids in Iran show a clear distinction between assemblages from the southern and northern margins of the Tethys during the Early Cretaceous.
