Two major groups of land plants dominated the landscape by Carboniferous time, the ...Permian Period, in geologic time, the last period of the Paleozoic Era, lasting from 298.9 million to 252.2 million years ago. The climate was warming throughout Permian times, and, by the end of the period, hot and dry conditions were so extensive that they caused a crisis in Permian marine and terrestrial life.

The Paleozoic Era began with the Cambrian Explosion, a relatively rapid period of speciation that kicked off a long period of life flourishing on Earth. Vast amounts of life forms from the oceans moved onto the land. Plants were the first to make the move, followed by invertebrates. Not long afterward, vertebrates took to the land.

Mesozoic Era, second of Earth’s three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for “middle life.” The Mesozoic Era began 252.2 million years ago, following the conclusion of the Paleozoic Era, and ended 66 million years ago, at the dawn of the Cenozoic Era.

The Devonian was a period of major atmospheric, climatic, and environmental changes, many of which can be linked to the spread of vascular land plants (Algeo et al., 2001; see Section 5.1) and to the incipient assembly of the supercontinent Pangea (Kidder and Worsley, 2004; see Section 5.2).Viewed from space, the Paleozoic Earth would be a foreign world. During this era, seas flooded the continents and receded several times. During the early Paleozoic three small continents— Laurentia, Siberia, and Baltica—split apart from the rest of the supercontinent Gondwana and formed the Lapetus Ocean in between.During the Mesozoic Era, both gymnosperm (conifers, etc.) and subsequently angiosperm plants evolved in forms comparable to their modern form. Plant growth also allowed the subsequent development of extensive coal beds. Like the Paleozoic, the Mesozoic Era closed with an episode of extinction.Cenozoic (66 million years ago until today) means ‘recent life.’ During this era, plants and animals look most like those on Earth today. Periods of the Cenozoic Era are split into even smaller parts known as Epochs, so you will see even more signposts in this Era. Cenozoic signposts are colored yellow.While the trilobites of the Paleozoic era and the overgrown chickens of the Jurassic may be long gone, some of the plants that dominated way back then are still alive and even thriving today. These “living fossils” can tell us a lot about the fascinating adaptations that plants have come up with. Scientists can study the advent of seeds ...

Life During the Paleozoic. The Paleozoic Era is literally the era of “old life.” It lasted from 544 to 245 million years ago and is divided into six periods. Major events in each period of the Paleozoic Era are described in Figure below. The era began with a spectacular burst of new life. This is called the Cambrian explosion. Cambrian Period, earliest time division of the Paleozoic Era and Phanerozoic Eon, lasting from 538.8 million to 485.4 million years ago. The Cambrian System, named by English geologist Adam Sedgwick for slaty rocks in southern Wales and southwestern England, contains the earliest record of abundant and varied life-forms.Characterized by a surge in biodiversity and evolutionary development, the Paleozoic Era ushered in the beginnings of life as we know it. Within these pages, readers will discover the fossil and geologic evidence from this time that reveals a dynamic planet, where new species of plants and animals were constantly emerging and continents were …The late Paleozoic rock strata hold the evidence of great forests of primitive plants thriving on land with their remains forming the great coal beds of Europe and eastern North America.

At present, fossil evidence of land plants dates to the Ordovician Period (about 485.4 million to 443.8 million years ago) of the Paleozoic Era.Fossilized cells, cuticles, and spores of early land plants have been dated as far back as the Ordovician period in the early Paleozoic era. The evolution of plants occurred by a gradual development of novel structures and reproduction mechanisms. At present, fossil evidence of land plants dates to the Ordovician Period (about 485.4 million to 443.8 million years ago) of the Paleozoic Era.Carboniferous Period.

Ordovician (490–435 Myr BP) Cambrian (543–490 Myr BP) Precambrian (beginning of the Earth – 570 Myr BP) For the Paleozoic era (570–236 Myr BP), more reliable data on the oceanic temperatures exist only for the late period ( the Permian ). However, there is evidence of large climate variations during the Paleozoic.For the Paleozoic era ... The development of simple plant life in the ocean was critical to the formation of an atmosphere that contained oxygen.
