摘要
虽然阿根廷中西部一些上古生界盆地已经被广泛研究，但其他盆地对生物地层学知之甚少。目前盆地间生物带的不均匀性可能是采样不完全的无脊椎动物化石组合的人工产物，妨碍了精确的相关性。因此，我们对在Arroyo del Imperial、Quebrada de La Horqueta和Cañón del Atuel的El Imperial组含化石层中发现的腕足动物进行了分类评估。发现了两个不同的生物带:(1)在Cañón del Atuel剖面发现了一个明显的莫斯科雅卡伦蒂夫托尼亚- inaequiornatus生物带(TS);(2)在Arroyo del Imperial和Quebrada de La Horqueta剖面中发现一个新的巴什基早期晚期saltospiri虫guevarae - periospira sanjuanensis生物带。TS菌群包括阿根廷菌stappenbecki, Oehlertella annae, Orbiculoidea saltensis, Coolkilella aredesi, Calytrixia piersoni, Costatumulus sp.和Septosyringothyris?sp组合包括Buxtonia riojana、Streptorhynchus inaequiornatus、septosyringgothyris (precosyringgothyris) feruglioi、septosyringgothyris (precosyringgothyris) jaguelensis、Spiriferellina sp.、Saltospirifer guevarai和sanjuanpericospira。El Imperial组腕足动物生物带为区域岩石地层单元间的精确生物对比提供了基础，并阐明了阿根廷中西部宾夕法尼亚纪上古生界的生物年代地层方案。Cristian Adrián Pardo [pardocr22@gmail.com]， Investigación Esquel de Montaña y Estepa Patagónica (CIEMEP) CONICET-UNPSJB, Roca 780, Esquel (U9200)，阿根廷Chubut。生物多样性研究实验室(LIEB)，自然科学与科学学院(FCNyCS)， esde Esquel, Aulas大厦，km 16.5, Esquel, chuut, U9200，阿根廷;c·奥古斯托·塔博达[ctaboada@mef.org.ar]， Paleontológico Egidio Feruglio (MEF)-CONICET博物馆，阿根廷丘布丘市特雷卢丰塔纳大街140号;Arturo csamar Taboada [taboadaart@gmail.com]， Investigación Esquel de Montaña y Estepa Patagónica (CIEMEP) CONICET-UNPSJB, Roca 780, Esquel (U9200)， Chubut，阿根廷。生物多样性研究实验室(LIEB)，自然科学与科学学院(FCNyCS)， esde Esquel, Aulas大厦，km 16.5, Esquel, chuut, U9200，阿根廷;María Alejandra Pagani [apagani@mef.org.ar]， Museo Paleontológico Egidio Feruglio (MEF)-CONICET, Avenida Fontana N°140,Trelew, Chubut, U9100GYO，阿根廷。
Pennsylvanian brachiopod faunas from the El Imperial Formation (San Rafael Basin) of central-western Argentina
Abstract While some Upper Paleozoic basins in central-western Argentina have been extensively studied, others have poorly understood biostratigraphy. The current biozone heterogeneity between basins could be an artefact of incompletely sampled invertebrate fossil assemblages preventing precise correlations. Here, we therefore provide a taxonomic assessment of brachiopods recovered from fossil-bearing beds of the El Imperial Formation at Arroyo del Imperial, Quebrada de La Horqueta, and Cañón del Atuel. Two distinct biozones are identified: (1) a conspicuous Moscovian Tivertonia jachalensis–Streptorhynchus inaequiornatus Biozone (TS) from the Cañón del Atuel section; (2) a new early late Bashkirian Saltospirifer guevarai–Pericospira sanjuanensis Biozone (SP) from the Arroyo del Imperial and Quebrada de La Horqueta sections. The TS assemblage includes Argentiella stappenbecki, Oehlertella annae, Orbiculoidea saltensis, Coolkilella aredesi, Calytrixia piersoni, Costatumulus sp. and Septosyringothyris? sp. The SP assemblage comprises cf. Buxtonia riojana, Streptorhynchus inaequiornatus, cf. Septosyringothyris (Precosyringothyris) feruglioi, cf. Septosyringothyris (Precosyringothyris) jaguelensis, ?Spiriferellina sp., Saltospirifer guevarai and cf. Pericospira sanjuanensis. The El Imperial Formation brachiopod biozones provide a basis for accurate biocorrelation between regional lithostratigraphical units, and clarify the Upper Paleozoic biochronostratigraphical scheme for central-western Argentina during the Pennsylvanian.
