How did the Ordovician period get its name?

Answer 1

The Cretaceous period got its name from the type of rock that was deposited along the northern shores of the Tethys seas at this periods time. This rock, formed from the metamorphosed deposits of the tiny limestone GH.LGUJLG of algae known as diatoms,is known as chalk.

Answer 2

The Permian period was named in 1841 by the geologist Murchison after a tour ofImperial Russia to include the "vast series of beds of marls, schists, limestones, sandstones, and conglomerates" that overlay the Carboniferous formations in the eastern part of the country. He named it after the ancient kingdom of Permia and the present city of Perm near the Ural mountains.

Answer 3

A scientist named Frederick von Alberti ,1795-1878, named the period of geological time where three layers of rock were overlayed. Triad meaning three. Red beds of sandstone overlaying white beds of chalk laid down about 65 million years ago

Answer 4

The Triassic period was named in 1834 by the German geologist Friedrich August Von Alberti (1795-1878) (it was originally named the "Trias"). It got its name because this period of geologic time is represented by a three-part division of rock types in Germany. These three distinctive rock layers are (from the bottom or earliest) the Bunter (which is brown sandstone and red beds), the Muschelkalk, and the Keuper. These are local rock types that are not found globally.

Answer 5

The Carboniferous period extended from approximately 360 Mya to about 300 Mya from the end of the Devonian Period to the beginning of the Permian Period. In the middle of this period the Carboniferous Rain forest Collapse occurred and resulted in the deposition of many coal beds. The name comes from the Latin word carbo which means coal. The word Carboniferous means coal-bearing.

Answer 7

The Ordovician era (~488.3 to 443.7 million years ago) was named for the Ordovices, a Celtic tribe.
