Trilobites. Trilobites are extinct arthropods. Usually, only the skeleton is found as a fossil, and is rarely complete. The skeleton covered the upper side of the body and has a head (cephalon) and a tail (pygidium) separated by a flexible, jointed thorax. The skeleton is also divided length-wise into three lobes (giving trilobites their name ... Late Paleozoic trilobites exhibit biogeographic patterns that parallel global warming, cooling and sea level changes. Early Mississippian trilobites exhibit increasing levels of endemism following the Hangenberg extinction. Beginning in the Late Mississippian trilobite's reduced endemism was concurrent with the onset of the Late Paleozoic Ice Age.This legendary dinosaur became extinct 65 million years ago... while in contrast, trilobites emerged more than 500 million years ago. Then to put the astonishing parameters of Geologic Time in a proper perspective, consider the following: the last trilobites (proteids) swam in the Permian oceans some 251 million years ago.
Trilobite. A Trilobite is an extinct arthropod. These creatures lived in the oceans until about 252 million years ago. Before their extinction, they persisted on Earth for an impressive 300 million years. Researchers place these extinct creatures in the taxonomic class Trilobita.

The eurypterids were one of the fiercest predators in ancient seas. Some reached more than two meters (six feet) in length, making them the largest arthropods that ever lived. The last ones went extinct about 245 million years ago.The Paleozoic ("old life") era is characterized by trilobites, the first four-limbed vertebrates, and the origin of land plants. The Mesozoic ("middle life") era represents the "age of dinosaurs," though also is noteworthy for the first appearances of mammals and flowering plants.
