Colonization of land by plants occurred during the paleozoic era about years ago.

Colonization of land by plants occurred during the paleozoic era about 200 milion years ago.

The Paleozoic Era is the earliest of three geologic eras of the Phanerozoic Eon. The Paleozoic Era is subdivided into six geologic periods: the Cambrian, Ordovician, Devonian, Carboniferous,  Silurian, and Permian. During the first period of the paleozoic era large number of creatures evolved, this is called Cambrian explosion. Whereas the Permian spanned from 299 to 252 million years ago and was the last period of the Paleozoic Era.  At the beginning of The Permian period, all continents joined together forming the supercontinent Pangaea, which was encircled by one ocean called Panthalassa.

The Paleozoic era occurred between 542 million years ago to 251 million years ago. The era began with the breakup of one supercontinent and the formation of another with Plants becoming widespread. Colonization of lands by plants occured during the Paleozoic era about 200 million years ago. Plants were among the earliest organisms to leave the water and colonize land The Devonian marks the beginning of extensive land colonization by plants, through their effects on erosion and sedimentation and brought the significant climatic change.

Colonization of land by plants occurred during the paleozoic era about 200 years ago.

Further Explanations:

The Palaeozoic Era was amongst the most primitive of the three geologic ages of the “Phanerozoic Eon”. The era was subdivided into six geological stages namely Carboniferous, Cambrian, Devonian, Silurian, Ordovician, and Permian. During the initial period of the era, numerous creatures evolved and this phenomenon was known as the “Cambrian explosion”. The Permian bridged amidst 299 to 252 million eons ago and was the preceding phase of the Palaeozoic Era.  

The era is known to have occurred amid 542 - 251 million eons ago. I began with the separation of the super continent Pangaea and then the formation of another continent with plants going with on it irregularly. Colonization by plants occurred somewhat since 200 million years. Plants were among the earliest entities to inhabit the land. The Devonian marked the beginning of most widespread land colonization by plants, through its effects of corrosion and sedimentation along with climatic change.
