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.

What period did life move to land?
The period during which life began to move on land was the Ordovician Period. It was during this time that evidence of plant spores from living fossils were found on land.
What are some important events that happened during the Ordovician time period?
You might see volcanic action.
During what period did the first vertebrates appear?
The first vertebrates evolved during the Cambrian Explosion about 525 million years ago. The Cambrian Explosion, obviously, occurred during the Cambrian period. The Cambrian period was part of the Paleozoic era.

Where did ostracoderms live?
Ostracoderms were a group of early jawless fish that lived in marine environments during the Paleozoic era. They were found in oceans worldwide, with fossil records indicating distribution in regions such as North America, Europe, and Australia.
