[3] Trilobites are a common fossil in many of the early to middle Paleozoic rocks of central Pennsylvania. These rocks range in age from 541 to 359 million years old. Complete fossil specimens are rare because a trilobite’s rigid outer skeletal segments were joined by flexible organic connections that decayed on the death of the animal. The Ordovician System rounded out the threefold paleontological division of the Early Paleozoic. The boundaries of Lapworth’s Ordovician System were based solely on its distinctive fossil content (Eicher 1976). Originally geologists defined the beginning of the Cambrian Period as the point where fossils appeared.Echinoids from the Paleozoic era had thin tests and their fossils are often incomplete, consisting of groups of plates or isolated spines. Later echinoids had more robust tests and fossilised well, usually with the spines detached from the test. Fossils of echinoids are common in rocks from the Jurassic and Cretaceous age, ...Fossils are important in understanding the history of the world because they provide physical evidence of animals and plants that lived in the past. Through their discovery, paleontologists uncover new ideas about former life on earth.Introduction. The Paleozoic Era was a major interval of geologic time. It began 541 million years ago with a rapid expansion of life-forms and ended 252 million years ago with the largest mass extinction in Earth’s history.
