摘要
在伊朗西北部(Zal和Poldasht地层剖面)的二叠纪-三叠纪沉积序列的Wordian中发现了一种新的小型双胺类有孔虫Globigaetania angulata gen. n. sp. n.。这一新分类群由Maurizio Gaetani教授发现，其独特的形态、卷曲和结构特征与Globivalvulininae Reitlinger亚科(1950)、Globivalvulinidae Reitlinger科(1950)、Biseriamminoidea Chernysheva超科(1941)相似。新分类群的引入有助于认识古生代双列微粒有孔虫的系统学和演化。
GLOBIGAETANIA ANGULATA GEN. N. SP. N. (GLOBIVALVULININAE, FORAMINIFERA) FROM THE WORDIAN (MIDDLE PERMIAN) OF NW IRAN
A new small biseriamminoid foraminifer, Globigaetania angulata gen. n. sp. n., is here described from the Wordian of a Permian –Triassic sedimentary succession of NW Iran (Zal and Poldasht stratigraphic sections). The new taxon, dedicated to Prof. Maurizio Gaetani, is characterised by peculiar morphology, coiling, and structures that are characteristic of the subfamily Globivalvulininae Reitlinger, 1950, family Globivalvulinidae Reitlinger, 1950, superfamily Biseriamminoidea Chernysheva, 1941. The introduction of the new taxon contributes to the knowledge of the systematics and evolution of the Palaeozoic biserial microgranular foraminifera.
期刊介绍：
The Rivista Italiana di Paleontologia e Stratigrafia was founded in 1895. It publishes original papers dealing with all fields of paleontology and of stratigraphy, from Italy and the Mediterranean to the Tethys, as well across the globe from China to North America.
