Open publisher page 2 citations

Abstract

Ordovician cold-water chitinozoan species, viz. Tanuchitina sp. cf. achabae Paris, Linochitina pissotensis Paris and Siphonochitina bella sp. nov., are discovered from the TZ-32 Well (the Charchaq Formation) and QB-1 Well (the Heituao Formation) in the Tarim Basin, Xinjiang, China. Species of Linochitina and Siphonochitina were mainly found from high latitude areas. The findings of these species in the Tarim Basin confirms that these cold-water origin genera can be obtained outside the Gondwanaland margin. The age of those fossils is Middle to Late Ordovician. Three species are described and illustrated in the present paper.
