晚石炭世早期腕足动物地理区划

BRACHIOPOD PALEOBIOGEOGRAPHY OF EARLY STAGE OF LATE CARBONIFEROUS

收集了全球范围内晚石炭世早期(Bashkirian—Moscovian期)的腕足动物化石共176属,同时参考珊瑚、菊石、植物等生物化石资料,将晚石炭世早期全球腕足动物划分为北极大区、特提斯大区和冈瓦纳3个大区.北极大区包括北美北部、北亚,晚石炭世早期腕足动物特征属为:Orulgania、Praehorridonia、Pseudosyrinx、Horridonia、Attenuatella、Tomiopsis、Syringothyris、Jakutoproductus、Alispirifer、Levipustula等凉水型分子;冈瓦纳大区包括南美南部、非洲南部、澳大利亚、我国藏南地区、印度、阿富汗等地区腕足动物典型属为:Levipustula、Alispirifer、Kitakamithyris、 Syringothyris、Trigonotreta等凉水型分子;特提斯大区分布于晚石炭世早期中低纬度地区,包括西欧、中南亚、非洲北部、格棱兰岛北美南部、南美北部等地区.腕足动物特征属为Enteletes、Orthotichia、Neochonetes、Juresania、 Derbyia、Reticulatia、Kutorginella、Meekella、Anthracospirifer、Kozlowskia等暧水型。

176 Brachiopod genus in the world, which is from Bashkiran～Moscovian in the early stage of late carboniferous was collected, then referring other fossils, three brachiopod realms of the early stage of late carboniferous are recognized, including Gondwana, Tethys and Boreal realm, the Boreal realm includes the north of North America, North Asia, it's chracteristic Genera are the coldwater brachiopods of Orulgania、Praehorridonia、 Pseudosyrinx、 Horridonia、 Attenuatella , Tomiopsis , Syringothyris , Jakutoproductus、Alispirifer、Levipustula.
