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 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.
Is it true the first land plants appeared during the paleozoic era?
Yes it is, and Liverworts were the first land plants.
What kinds of plants lived in the Cenozoic era?
a few plants that lived during the Cenozoic era were Birch&&Sweetgum
The second era in geological time?
Warm, shallow seas covered most of Earth's surface near the end of the Paleozoic Era.
Where did most of the paleozoic era life forms live?
They lived in the ocean because they were marine animals.
