The plants and animals found in concretions recovered from the Francis Creek Shale are some of the most exciting and important fossils that have been found in the state of Illinois. These fossils are known as the Mazon Creek fossils, because they were originally found along Mazon Creek in northeastern Illinois. ...

The Cambrian Period marks an important point in the history of life on earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the Cambrian Explosion , because of the relatively short time over which this diversity of forms appears. It was once thought that the Cambrian rocks contained the first and oldest fossil animals, ...

The Paleozoic Era The Paleozoic is bracketed by two of the most important events in the history of animal life. At its beginning, multicelled animals underwent a dramatic explosion in diversity, and almost all living animal phyla appeared within a few millions of years. At the other end of the Paleozoic, the largest mass extinction in history wiped out approximately 90% of all marine animal ...

The Devonian 410 to 360 Million Years Ago The Rhynie Chert in Scotland is a Devonian age deposit containing fossils of both Zosterophyllophytes and Trimerophytes, the two major lines of vascular plants. This indicates that prior to the start of the Devonian, the first major radiations of the plants had already happened. The oldest known vascular plants in the Northern Hemisphere are Devonian.

Paleozoic Era, The Permian Period.

The Carboniferous 360 to 286 Million Years Ago The Carboniferous Period occurred from about 360 to 286 million years ago during the late Paleozoic Era. The term Carboniferous comes from England, in reference to the rich deposits of coal that occur there. These deposits of coal occur throughout northern Europe, Asia, and midwestern and eastern North America. The term Carboniferous is used ...

Carboniferous Period 362-290 Million Years Ago. During this period snakes emerged as well as salamander type amphibians.

The Permian 286 to 245 Million Years Ago The Permian period lasted from 286 to 245 million years ago and was the last period of the Paleozoic Era. The distinction between the Paleozoic and the Mesozoic is made at the end of the Permian in recognition of the largest mass extinction recorded in the history of life on Earth. It affected many groups of organisms in many different environments, but ...

The Ordovician 505 to 440 Million Years Ago The Ordovician period began approximately 510 million years ago, with the end of the Cambrian, and ended around 445 million years ago, with the beginning of the Silurian. At this time, the area north of the tropics was almost entirely ocean, and most of the world's land was collected into the southern super-continent Gondwana. Throughout the ...

Permian Period Animal Printout. Many amazing animals lived during the Permian Period, which ended with the largest mass extinction in the history of the Earth.

The Silurian 440 to 410 Million Years Ago The Silurian (440 to 410 million years ago) was a time when the Earth underwent considerable changes that had important repercussions for the environment and life within it. The Silurian witnessed a relative stabilization of the earth's general climate, ending the previous pattern of erratic climatic fluctuations. One result of these changes was the ...
