EVENT STRATIGRAPHY AND CORRELATION PROBLEMS OF THE ORDOVICIAN STRATA OF GORNY ALTAI AND SALAIR
Study of the Ordovician sedimentary sequences of Gorny Altai and Salair has revealed lithological and paleontological features correlating with global sedimentary events:(1) The Acerocare Regressive Event (an initial event in the Early Tremadocian);(2 ...

Abstract The current study presents new bed‐by‐bed brachiopod δ13C and δ18O records from Öland, Sweden, which together with previously published data from the East Baltic region, constitutes a high‐resolution paired brachiopod and bulk rock carbon and oxygen isotope archive through the Lower to Upper Ordovician successions of Baltoscandia.

Allogenic succession in Late Ordovician reefs from southeast China: a response to the Cathaysian orogeny [PDF]
Several Late Ordovician (late Katian) reef complexes are known from the border area of Jiangxi and Zhejiang provinces in southeast China. We studied two coral–stromatoporoid reefs exposed in the Xiazhen Formation at Zhuzhai (Yushan, Jiangxi).

Ordovician climate changes in the northern subtropics: The δ18O record from the Tunguska Basin, Siberia [PDF]
Oxygen isotopes from bioapatite (conodonts) have been used for several decades to reconstruct the Palaeozoic climate history. During the Ordovician, conodont-based δ18Ophos studies have revealed a general cooling trend throughout the system.

Late Ordovician jawed polychaete fauna from the Spiti Valley, northern India [PDF]
The final part of the Ordovician Period was characterised by major perturbations in climate, environments and ecosystems, as proved by numerous studies. These changes resulted in one of the biggest extinctions in Earthâs history. Most research in early

Palaeozoic correlations and the Palaeogeography of the Sibumasu (Shan-Thai) Terrane - a brief review [PDF]
Furongian sandstones yield shallow-water trilobite faunas along the length of the Sibumasu Terrane in the four regions of NW Malaysia (Langkawi), southern Thailand (Satun), the Shan States of Myanmar and the Baoshan Block of western Yunnan.

A new Late Ordovician bubble-headed trilobite species from South West Wales and its implications for biostratigraphy [PDF]
A new species of bubble-headed trilobite, Staurocephalus oliveae sp. nov., is described from 250 specimens collected from a recently discovered locality in the Sholeshook Limestone Formation (upper Katian, Upper Ordovician; Ashgill, Cautleyan Zone 1 ...
