The importance of Hindeodus parvus (Conodonta) for the definition of the Permian-Triassic boundary and evaluation of the proposed sections for a global stratotype section and point... by Yurij D. Zakharov, Cheng-yuan Wang, Anton Ramovš, Heinz W. Kozur

“…The biostratigraphic Permian/Triassic (P/T) boundary is defined by the first appearance of H. parvus. The first appearance of H. parvus within the dine H. latidentatus-H. parvus is a globally recognizable event in the conodont evolution.The first appearance of H. parvus is not facies related and can be observed both in ammonoid-free shallow-water deposits and in ammonoid-bearing pelagic deposits. …”

Guadalupian (Middle Permian) Conodonts of Sponge-Bearing Limestones from the Margins of the Delaware Basin, West Texas by Heinz W. Kozur, Helfried Mostler

“…For this reason, the top of the Guadalupian can be well correlated with the Tethyan scale, in which the Late Permian Lopingian Series is defined. The first appearance of Clarkina crofti KOZUR & LUCAS in the uppermost Lamar Limestone and in the uppermost Altuda Formation is very important as it is penecontemporaneously with the first appearance of C. altudaensis. …”

Alans in Mongol Service in First Third of 13th Century by E. V. Kaziev

“…The author considers actual and, despite the presence of a number of written medieval sources and a wide consideration of the topic in scientific literature, discussion questions about the Alans who were in the service of the Mongol Kaans and emperors of the Yuan dynasty, and about the time of the first appearance of the Alans in the Mongol service. The novelty of this study lies in the fact that the question of establishing the time of the first appearance of the Alans in the service of the Mongols is solved in it through determining the time of the introduction of Mongol rule in the territory of the Ciscaucasia. …”
