This means that rocks from the Phanerozoic contain fossils, lots of fossils! The Paleozoic period lasted about million years, from about million years ago to about million years ago. So much happened during the Paleozoic that it is divided into seven geologic time periods, shown on the red steps of the "Staircase of Time".

Oct 30, · The Paleozoic (or Palaeozoic) Era is the earliest of three geologic eras of the Phanerozoic Eon, spanning from roughly to million years ago (ICS, ). It is the longest of the Phanerozoic eras, and is subdivided into six geologic periods (from oldest to least old): the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and.
Ordovician: Stratigraphy. The Ordovician was named by the British geologist Charles Lapworth in He took the name from an ancient Celtic tribe, the Ordovices, renowned for its resistance to Roman domination. The epochs and series of the Ordovician each have a type location in Britain, where their characteristic faunas may be found. limestones of southern Ontario, Canada: Storm sedimentation on a shoal-ba% shelf model. Sediment. Geol., The mid-Ordovician (Caradocian) limestones of southern Ontario were deposited on a rhelf undergoing collision with a magmatic arc. Within the general deepening-upwards sequence, shoals and islands complicate the facies.

Overlying the Canadian Shield in the far north and in southern Ontario are young sedimentary rocks which range in age from to million years. The fossil evidence suggests that these sedimentary rocks were formed when Ontario was flooded by shallow, tropical seas.
THE PALEOZOIC AND MESOZOIC ROCKS; A DISCUSSION TO ACCOMPANY THE GEOLOGIC MAP OF THE UNITED STATES By PHILIP B. KING and HELEN M. BEIKMAN ABSTRACT This report deals with the Paleozoic and Mesozoic rocks that are exposed within the area covered by the Geologic Map of the United States and treats them in terms of the map legend.

Middle Ordovician platform carbonates on the Mingan Islands are characterized by two major paleokarst unconformities and numerous local paleokarst surfaces which are today exposed on extensive bedding planes. The lower paleokarst unconformity was developed on Lower Ordovician dolomites (Canadian to earliest Whiterockian) of the Romaine rafaelrvalcarcel.com by: permeability rocks themselves.
