title: Data from: Katian (Late Ordovician) trilobites of the North Qilian Mountains and their palaeogeographical implications for the Proto-Tethys Archipelagic Ocean (PTAO)

description: Trilobites from the middle Koumenzi Formation (Katian, Upper Ordovician)
 of the North Qilian Mountains, Menyuan, northeastern Qinghai Province are
 systematically documented for the first time. The fauna consists of five
 families, seven genera and seven species, amongst which one is new
 (Remopleurides zhangi sp. nov.), showing a close relationship to those of
 the Kazakh terranes (such as Chu-Ili terrane, Chingiz-Tarbagatai area and
 KNNTS (Karatau-Naryn and North-Tien Shan Microcontinents)), North China
 and Laurentia palaeoplates during the Katian (Late Ordovician). The
 cluster and Non-metric Multidimensional Scaling analyses of the
 Middle–Late Ordovician (late Darriwilian–Katian) trilobite faunas with 299
 genera or subgenera from 46 horizons of 37 areas, provide valuable
 information for the palaeogeographical reconstruction of the Proto-Tethys
 Archipelagic Ocean (PTAO) of this interval. The Qilian terrane and
 adjacent areas are essential components of the PTAO, some of which include
 the Qilian terrane (QT), the North Qilian Mountains area (NQ), the Altun
 faulted terrane (AFT), the Hexi Corridor area (HX) and the East Qinling
 terrane (EQT). Their relative positions within the PTAO are inferred by
 the palaeobiogeography of trilobite faunas. Based on further discussions
 on the spatiotemporal distribution of those faunas, the Pliomerina and/or
 Sinocybele Province of the Middle–Late Ordovician (late
 Darriwilian–Katian) age is defined as a trilobite faunal province of the
 PTAO. Moreover, a distinct faunal subprovince, essentially comprised of
 the South China Palaeoplate and its neighbours (e.g. Tarim, Annamia,
 Sibuma, East Qinling, Turkestan-Alai and probably Talesh), might be
 surrounded by the equatorial cold-water tongue.

 file of this dataset. 3. Additional related data collected that was not
 included in the current data package: No. 4. Are there multiple versions
 of the dataset? yes/no No. METHODOLOGICAL INFORMATION 1. Description of
 methods used for collection/generation of data: To investigate the
 palaeogeographical significance of a new trilobite fauna in the
 reconstruction of the ProtoTethys Archipelagic Ocean, 299 genera or
 subgenera of roughly late Middle to early Late Ordovician age were
 selected, and their presence or absence from 46 horizons in 37
 geographical areas was determined. The data were collected from published
 papers and monographs. 2. Methods for processing the data: The data have
 not been processed by any method. 3. Instrument- or software-specific
 information needed to interpret the data: No specific information needed
 to interpret the data. 4. Standards and calibration information, if
 appropriate: None 5. Environmental/experimental conditions: None 6.
