      Cambrian: Stratigraphy. A lot can happen in 40 million years, the approximate length of the Cambrian period. Animals showed dramatic diversification during this period of Earth's history. This has been called the "Cambrian Explosion".

Stratigraphic framework of Cambrian and Ordovician rocks in the central Appalachian Basin from Medina County. The Stratigraphy of the Cambrian period currently has several schemes used for ordering geologic formations from the period.

The International Commission on Stratigraphy−ICS scheme has set a stratotype section for the base of the Cambrian, dated quite accurately to ± million years ago.

Russian and Chinese scientists have developed a different scheme. Stops in this field trip will focus on the succession of rocks exposed in the Frederick Valley and Great Valley of central Maryland and the Nittany arch of central Pennsylvania (Fig.

Stratigraphy of the Cambrian is part of WikiProject Geology, an attempt at creating a standardized, informative, comprehensive and easy-to-use geology resource. If you would like to participate, you can choose to edit this article, or visit the project page for more information.

Start This article has been rated as Start-Class on the project's quality scale. Because the international stratigraphic subdivision is not yet complete, many local subdivisions are still widely used.

In some of these subdivisions the Cambrian is divided into three epochs with locally differing names – the Early Cambrian (Caerfai or Waucoban, ± to ± mya), Middle Cambrian (St Davids or Albertan, ± to ± mya) and Furongian ( ± to.

The Cambrian and Ordovician systems originated from study of rock successions in Wales, and the resulting classification set a stratigraphical standard that was adopted worldwide.

For example, the development of graptolite biostratigraphy owed much to Lapworth’s pioneering 19th century studies of Scottish and Welsh successions, which ultimately contributed to the existing Lower Palaeozoic.
