The Paleozoic Era was full of new life and of extinction. However, in the Ordovician Period, the plant life found was green and red algae (Christmas colors!) and stromatoporoids. Stromatoporoids are sponge life creatures that invertebrates, and were ecspecially helpful in reef-forming. The climate in the Ordovician Period was warm and tropical, yet cold and moist. There where, however, many volcanos going off at this time, making it very blackend and rocky. The animals living in this time had mollusks, anthropods, cephalopods, brachipod, trilobite (everywhere!), and orthocerida.
What else can I help you with?
Which life forms dominates the early middle and late parts of paleozoic era?
During the early Paleozoic era, marine invertebrates such as trilobites dominated. In the middle Paleozoic, fish and early land plants became more prominent. By the late Paleozoic, amphibians, reptiles, and forests of ferns and seed plants were thriving.
What life form that lived during the Paleozoic period is an important index fossil?
The life forms that lived during the Paleozoic are Permian, the Carboniferous, (both the Mississippian and the Pennsylvanian), the Devonian,the Silurian, the Ordovician, the Cambrian, and the Precambrian. The Paleozoic Era lasted from 570 to 225 Million Years Ago. Complex forms of life appear. During this 345 million year period, plants and animals underwent rapid evolution.The Paleozoic era lasted about 345 million years. It includes the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian periods. Index fossils of the first half of the Paleozoic era are those of invertebrates, such as trilobites, graptolites, and crinoids. Remains of plants and such vertebrates as fish and reptiles make up the index fossils of the second half of this era.
Ask us anythingMatch the time frame listed on the left with the characteristic listed on the right. A. Mesozoic era Tyrannosaurus Rex lived. B. End of the Paleozoic era The largest mass extinction hap?
A. Mesozoic era - Tyrannosaurus Rex lived during the late Mesozoic era, specifically in the late Cretaceous period. B. End of the Paleozoic era - The largest mass extinction event, known as the Permian-Triassic extinction event, occurred at the end of the Paleozoic era, approximately 252 million years ago.
The second era in geological time?
The second era in geological time is the Paleozoic era, which lasted from about 541 million years ago to 252 million years ago. It is known for the evolution of early marine life, the colonization of land by plants and animals, and the formation of the supercontinent Pangaea. Major events during this era include the Cambrian explosion, the colonization of land by plants during the Silurian period, and the mass extinction at the end of the Permian period.
Many of the plants in a paleozoic forest would have belonged to the division lycophyta?
Yes, during the Paleozoic era, lycophytes, which are primitive vascular plants, were dominant in forests. These plants had small leaves and reproduced by spores. Lycophytes contributed significantly to the vegetation that existed during that time period.
Seed plants which first appeared in the Paleozoic Era?
Gymnosperms.
Plants and animals began to live on land during this era?
paleozoic
Which era do did first mammal dinosaurs and plants appeared in?
Mammals and dinosaurs emerged in the Mesozoic era. Plants appeared in the Paleozoic era, which came before it.
Which life forms dominates the early middle and late parts of paleozoic era?
During the early Paleozoic era, marine invertebrates such as trilobites dominated. In the middle Paleozoic, fish and early land plants became more prominent. By the late Paleozoic, amphibians, reptiles, and forests of ferns and seed plants were thriving.

A. Mesozoic era - Tyrannosaurus Rex lived during the late part of the Mesozoic era, specifically in the Late Cretaceous period. B. End of the Paleozoic era - The largest mass extinction event occurred at the end of the Paleozoic era, known as the Permian-Triassic extinction event, which led to the loss of a significant percentage of species on Earth.
The second era in geological time?
The second era in geological time is the Paleozoic era, which lasted from about 541 million years ago to 252 million years ago. It is known for the evolution of early marine life, the colonization of land by plants and animals, and the formation of the supercontinent Pangaea.

What is the 1st period in the Paleozoic Era?
The first period in the Paleozoic Era was the Cambrian.
What are the names of the eras?
The Eras go like this: Precambrian Era Paleozoic Era Mesozoic Era Cenozoic Era Dinosaurs lived during the Mesozoic Era, and we live in the Cenozoic Era. Paleozoic means "ancient life" Mesozoic means "middle life" Cenozoic means "recent life" All eras end in a huge disaster
What era is silurian in?
The Paleozoic Era
What organism dominated the paleozoic era?
It's not much of the organisms that dominated the paleozoic era, it's the species of animals. Alot of the larger reptiles and early ancestors of dinosaurs conquered and dominated the paleozoic era.
Many of the plants in a paleozoic forest would have belonged to the division lycophyta?
Yes, during the Paleozoic era, lycophytes, which are primitive vascular plants, were dominant in forests. These plants had small leaves and reproduced by spores. Lycophytes contributed significantly to the vegetation that existed during that time period.
