Precambrian Era
The Mesozoic era.
Plants and animals first reached land during the Silurian period, which is part of the Paleozoic era. This occurred approximately 420 million years ago. These early land organisms played a crucial role in shaping terrestrial ecosystems and paving the way for future life on land.
The middle Paleozoic era is known as the Devonian period. The period ended with the death of many species of vertebrate life. During this time, many life forms transitioned from living in the water to living on land.

HORRIBLE!
During the Paleozoic era, which lasted from about 541 to 252 million years ago, key events included the Cambrian explosion marking the rapid diversification of multicellular life, the colonization of land by plants and insects during the Ordovician and Silurian periods, the emergence of fish and later tetrapods, and the extensive coal swamps of the Carboniferous period. The era ended with the Permian extinction, the largest mass extinction in Earth's history.
The colonization of land by plants did not occur during the Cenozoic era as it happened earlier during the Paleozoic era.
The Paleozoic Era, because rich fossil evidence displays that early life in the time of the Paleozoic Era, there existed a dicersity of marine life.

Mammals evolved adaptations that allowed them to live on land, in the air, and in the water during the Cenozoic Era. The Cenozoic Era began approximately 65 million years ago.
Life first appeared on land around 500 million years ago during the Ordovician Period. Plants and some arthropods were among the first organisms to colonize terrestrial habitats, followed by amphibians and eventually reptiles.
