Transcript of Silurian Period
He was studying rocks from this age and realized they were younger than the Cambrian and older than the Devonian
This period is named after the Silures, an ancient Celtic tribe that lived along the now Welsh-English border This period lasted from 416 mya to 444 mya
Overall it lasted 28 my
This was during the Paleozoic Era and the Phanerozoic Eon Important Geologic Events Gondwana drifted across the South Pole
At the end of this age Laurentia and Baltica collided forming Euramerica raising mountain ranges
Rising sea level formed a nearly continuous sea from New York to Nevada
Other shallow seas covered parts of other continents
The Equator was in North America Climate In the early Silurian period high altitudes were covered by ice sheets
Later the climate warmed globally
A greenhouse phase later began, melting ice sheets and raising sea levels Rocks and Minerals In the mid-US precipitation of limestone, dolomite, gypsum and halite from ocean water was occuring
Shale and sandstone formed from the Taconic Mountain Erosion
