The Sandbian is the first stage of the Upper Ordovician.It follows the Darriwilian and is succeeded by the Katian.Its lower boundary is defined as the first appearance datum of the graptolite species Nemagraptus gracilis around 458.2 million years ago.

Fossils of this plant have been recorded in Australia, [39] [40] Canada, [41] and China. [42] Eohostimella heathana is an early, probably terrestrial, "plant" known from compression fossils [43] of Early Silurian (Llandovery) age. [44] The chemistry of its fossils is similar to that of fossilised vascular plants, rather than algae. [43]
The Late Ordovician glaciation is widely considered to be the leading cause of the Late Ordovician mass extinction, [2] [12] and it is the only glacial episode that appears to have coincided with a major mass extinction of nearly 61% of marine life. [13]
The Devonian (/ d ə ˈ v oʊ n i. ən, d ɛ-/ də-VOH-nee-ən, deh-) [9] [10] is a geologic period and system of the Paleozoic era during the Phanerozoic eon, spanning 60.3 million years from the end of the preceding Silurian period at 419.62 million years ago (), to the beginning of the succeeding Carboniferous period at 358.86 Ma.
In fact, the Hirnantian (also known as the End Ordovician and the Ordovician-Silurian) mass extinction event represents the second largest such event in geologic history. Approximately 85% of marine (sea-dwelling) species died. Only the End-Permian mass extinction was larger. Unlike many smaller extinction events, however, the long-term ...
The Ordovician saw the highest sea levels of the Paleozoic, and the low relief of the continents led to many shelf deposits being formed under hundreds of metres of water. [41] The sea level rose more or less continuously throughout the Early Ordovician, leveling off somewhat during the middle of the period. [41]
