Abstract

Six Early Carboniferous brachiopod species in four genera of the Superfamily Spiriferoidea are described from the Qaidam Basin, northwestern China, including a new genus, Qaidamospirifer, and two new species: Grandispirifer qaidamensis and Qaidamospirifer elongatus. Additionally, a new genus, Triangulospirifer, is also proposed to replace Triangularia Poletaev, 2001 that was preoccupied by a Devonian molluscan genus.

On the basis of the new material as well as published information, we have reviewed the taxonomic composition and the stratigraphic and palaeobiogeographic distributions of the three previously established genera from the viewpoint of palaeobiogeography. The study reveals that Grandispirifer has a relatively long stratigraphic range from the late Tournaisian to Serpukhovian. During this interval, the genus attained a wide geographical distribution, reaching Northwest China, western Yunnan of West China, Japan, as well as Iran and North Africa. Angiospirifer first occurred in western Europe in the Viséan, and later migrated to North Africa during the late Viséan. In the Serpukhovian, it migrated eastward, reaching the Donets Basin of Ukraine and the Qaidam Basin in Northwest China. Anthracothyrina evolved from Brachythyrina in North Africa in late Viséan, then dispersed north-westward to western and eastern Europe and, further eastward to the Qaidam Basin during the Serpukhovian.

Introduction

The Early Carboniferous brachiopod faunas from the Qaidam Basin in Northwest China (Fig. 1) have received limited attention, due to the area's remoteness and poor accessibility. As a follow-up study of the Early Carboniferous athyridid brachiopods from the Qaidam Basin (Chen et al., 2003), the present paper focuses specifically on the spiriferoids. The detailed taxonomy of these spiriferoids not only allows us to further constrain the age of the faunas, but also provides new insights into the biogeographical aspects of the Early Carboniferous brachiopod faunas as constrained by the contemporaneous palaeogeographic/palaeoclimatic conditions of the Qaidam Basin and neighbouring tectonic blocks.

Stratigraphy and age

Although a number of stratigraphic studies have been published for the Qaidam Basin in Northwest China (e.g., Lu and Zhao, 1962, Yang et al., 1962a, Yang et al., 1962b, Mu et al., 1963a, Mu et al., 1963b, Mu et al., 1963c, Wang, 1981, Wang, 1987, Wang, 1990, Shi, 1983), the detailed Lower Carboniferous stratigraphy of this basin was not firmly established until recent times. According to Chen et al. (2003), the Lower Carboniferous in the Qaidam Basin is sandwiched between the underlying

Palaeobiogeographic distributions: centres of origin and migratory paths of Grandispirifer, Angiospirifer, and Anthracothyrina

Grandispirifer Yang, 1959 has been known from widely distributed areas in the Palaeo-Tethys during the Viséan (Table 1). The genus was originally erected with materials from the lower Viséan succession of the northern Tienshan areas, Xinjiang, Northwest China (Yang, 1959, Yang, 1964). Later, it was also reported from the Viséan of the southern Junggar Basin, Xinjiang, Northwest China (Zhang et al., 1983); of western Yunnan, Southwest China (Jin, 1987); and of the Akiyoshi Limestone Group,

Systematic palaeontology

The classification of the Spiriferoidea adopted here follows Carter et al. (2006) and Gourvennec and Carter (2007). All morphological terms are in current use, as in Brunton et al. (1996) and Williams and Brunton (1997). All described specimens were collected from the Lower Carboniferous Chuanshangou section in the Amunike Mountain, Wulan County, Qinghai Province, Northwest China (Fig. 1) by one of the authors (ZLP) and his colleagues from the Chinese Academy of Geological Sciences from 1976 to
