Detailed studies of upper Cisuralian (i.e., upper lower Permian) fusulinids make it possible to decipher the paleobiogeographic relations of central Iran, as part of the Cimmerian terranes, with other Paleotethyan regions. Two sections, Bagh-e Vang and Shesh Angosht, located in east-central Iran, are revised. Four local fusulinid biozones are distinguished: upper Yakhtashian Pamirina darvasica and Sakmarella spp. Zone, lower Bolorian Misellina (Brevaxina) dyrhenfurthi Zone, mid-Bolorian Cuniculinella Zone, and upper Bolorian Misellina (Misellina) cf. M. (M.) termieri Zone (probably equivalent to the traditional Misellina (Brevaxina) parvicostata Zone). Taxonomically, the main results are as follows: (1) a clarification is provided of the fusulinid genus or subgenus “Cuniculina,” the name of which is pre-occupied, and its synonymy with Cuniculinella; and (2) a lectotype is designated for Darvasites (Alpites) sinensis (Chen, 1934). The mid-Bolorian Cuniculinella Zone is recognized for the first time in Iran. Among the Bolorian fusulinids, Cuniculinella is reported in SE Pamir, Karakoram, central Afghanistan, SW Japan, central Japan, and California, confirming the faunal affinity of the study area in east-central Iran with both Paleotethyan and Panthalassan bioprovinces. Such a distribution is considered to have resulted from combined effects of global warming during the upper Cisuralian, warm oceanic currents along the Paleotethys Ocean, and the northward drift of the Iran block toward lower paleolatitudes.

来自伊朗中东部的上 Cisuralian（上 Yakhtashian-Bolorian）有孔虫的生物地层学、分类学和古生物地理学，同时澄清了 Fusulinid 属 Cuniculinella 和 Cuniculina 的分类学

对上西苏拉纪（即上下二叠纪）梭状科的详细研究，可以破译作为西梅里阶地体一部分的伊朗中部与其他古特提斯地区的古生物地理关系。对位于伊朗中东部的 Bagh-e Vang 和 Shesh Angosht 两个部分进行了修订。区分了四个当地的梭菌类生物区：上雅赫塔什帕米里纳和萨克马雷拉spp. 下博洛里安区米塞利纳(布雷瓦西娜)地伦富蒂中波洛里安区库尼库尼拉区和上波洛里安米塞利纳(米塞利纳) 参照。米. (米.)特梅里区域（可能相当于传统的米塞利纳(布雷瓦西娜)细小虫区）。从分类学上看，主要结果如下：（1）阐明了镰孢菌属或亚属“库尼库利纳，”其名称被占据，它的同义词是库尼库尼拉; (2) 选型被指定用于达瓦西人(阿尔卑斯山)中华（陈，1934）。中波洛里安人库尼库尼拉区域在伊朗首次得到认可。在Bolorian fusulinids中，库尼库尼拉在东南帕米尔、喀喇昆仑、阿富汗中部、日本西南部、日本中部和加利福尼亚报道，证实了伊朗中东部研究区与古特提斯和潘塔拉桑生物省的动物群亲和性。这种分布被认为是由于上西苏拉纪全球变暖、古特提斯洋沿岸温暖洋流以及伊朗地块向低古纬度向北漂移的综合影响。
