The Silurian is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at 443.8 million years ago (Mya), to the beginning of the Devonian Period, 419.2 Mya. The base of the Silurian is set at a series of major Ordovician Silurian extinction events when up to 60% of marine genera Lower to Upper Devonian (Kaskaskia-i Sequence) Laurentian margin, corresponding to the middle part of the Kaskaskia-I sequence.

Denis Lavoie, in The Sedimentary Basins of the United States and Canada (Second Edition), 2019 Western Yunnan and the major part of Xizang (including northern Xizang of the Himalayas) featured continuous Silurian-Devonian deposition, yielding common fossils such as brachiopods Stringocephalus and from Hou & Wang (1985) and new data from various sources.
