What is "laurentia"

Laurentia (North American Craton) is a large continental craton that forms the ancient geological core of the North American continent. Many times in its past, Laurentia has been a separate continent as it is now in the form of North America, although originally it also included the cratonic areas of Greenland and also the northwestern part of Scotland, known as the Hebridean Terrane. During other times in its past, Laurentia has been part of larger continents and supercontinents and itself consists of many smaller terranes assembled on a network of Early Proterozoic orogenic belts. Small microcontinents and oceanic islands collided with and sutured onto the ever-growing Laurentia, and together formed the stable Precambrian craton seen today.

The craton is named after the Laurentian Shield, which in turn is named after the Laurentian Mountains.

Laurentia is a genus of snout moths. It was described by Ragonot in 1888.

Laurentia is a bioregion atop the Laurentian craton in the northeastern United States and eastern Canada, and centering on the Great Lakes.

The bioregion spans the Eastern Woodlands of North America from the easternmost part of the Great Plains to the Atlantic Coast of the Northeastern United States and Canadian Maritimes. From north to south, it spans from the edge of the boreal forest in Canada, generally up to approximately the 50th parallel give or take a couple degrees of latitude and south to approximately the Ohio River, Potomac River and Ozarks.

The largest ecoregion within Laurentia is called the Laurentian Mixed Forest Province.
