Plants from the paleozoic era.
the Palaeozoic, an era of arthropods, amphibians, fishes, and the first life on land; the Mesozoic, which spanned the rise, reign of reptiles, climactic extinction of the non-avian dinosaurs, the evolution of mammals and birds; and. the Cenozoic, which saw the rise of mammals. The Phanerozoic is divided into three eras: the Paleozoic, Mesozoic ...
Important Events of the Paleozoic: Carboniferous (354-290 million years ago): The first "forests" composed of large primitive trees provide a swampy habitat for early reptiles. Devonian (417-354 million years ago): Certain fish develop the ability to crawl onto land, leading to the evolution of the first amphibians. Silurian (443-417 million years ago): …This era was between about 250 to 66 million years ago. During this period, life evolved and diversified. It gets its name from the Greek language, which means ‘Middle life.’. This period is also famous as the age of dinosaurs or the age of reptiles. The Mesozoic era existed between the Paleozoic and the Cenozoic era.However, the swamps bearing these plants would dry up before the end of the Paleozoic era. A gap in the rock record spans the remainder of the Paleozoic after the end of the Carboniferous because local sediments were being eroded away faster than they were being deposited. During the Mesozoic, Pangaea began to break apart.Paleozoic Era, or Palaeozoic Era, Major interval of geologic time, c. 542–251 million years ago. From the Greek for “ancient life,” it is the first era of the Phanerozoic Eon and is followed by the Mesozoic Era.

The era encompasses six geologic periods, and from youngest to oldest, they are: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The Paleozoic was a time of extreme evolutionary change and the foundations of life as we know it were set during this period. Immediately prior to the Paleozoic, there were few, if any animals ...
Trilobites were increasingly scarce while foraminifers were abundant. The heavily armored fish from the Devonian became extinct, being replaced with more modern-looking fish fauna. Though many spectacular plant forms dominated the Carboniferous, most of them disappeared before the end of the Paleozoic.
The Carboniferous Period is famous for its vast swamp forests, such as the one depicted here. Such swamps produced the coal from which the term Carboniferous, or "carbon-bearing," is derived. The Carboniferous Period lasted from about 359.2 to 299 million years ago* during the late Paleozoic Era.

Mesozoic. Mesozoic (252-66 million years ago) means 'middle life' and this is the time of the dinosaurs. This era includes the Triassic, Jurassic, and Cretaceous Periods, names that may be familiar to you.

A glacial period during the Ordovician is evidenced by widespread …What plants were on Earth during the Ordovician Period? The first land plants appeared. They were similar to mosses and other plants without deep roots or leaves. What was Virginia like during the Ordovician Period? Near the end of this period, North America and northern Europe collided, forming the Taconic Mountains north of Virginia.The periods that followed the Cambrian during the Paleozoic Era are marked by further animal evolution and the emergence of many new orders, families, and species. As animal phyla continued to diversify, new species adapted to new ecological niches. During the Ordovician period, which followed the Cambrian period, plant life first appeared on land.Vascular plants that surfaced during this period (known as Cooksonia) enabled plants to earn a foothold on land, while the recent rise in sea levels resulted in a significant increase in water-based species. ... The last period of the Paleozoic Era was the Permian Period, which started off in spectacular fashion, marked by a joining of the ...
Cambrian Period (540-485 million years) The Cambrian Period is the oldest of the named geological periods of the Paleozoic Era. At the beginning of the Cambrian Period the combination of tectonic …The Paleozoic Era (541-252 Ma) is before the Mesozoic Era. There is rapidly land plants evolvement into the vacant niches so they could thrive on land. It was a time for plant innovation and evolution. During this time land plants evolve to emerge from water, first as moss-sized plants. After that become towering trees by the end of period.
