In North America, the Paleozoic is characterized by multiple advances and retreats of shallow seas and repeated continental collisions that formed the Appalachian Mountains. Common Paleozoic fossils include trilobites and cephalopods, as well as insects and ferns. The greatest mass extinction in Earth's history ended this era.Paleozoic Era. Tens of thousands of feet of Paleozoic sediments have been found in the central United States alone, layer upon layer upon rock. We can look at these from the lowest level of rock, from nearly 570 million years ago, right up through the whole Paleozoic; and see the succession of changing life as we go through these rock cuts.The Ordovician (/ ɔːr d ə ˈ v ɪ ʃ i. ə n,-d oʊ-,-ˈ v ɪ ʃ ən / or-də-VISH-ee-ən, -⁠doh-, -⁠ VISH-ən) is a geologic period and system, the second of six periods of the Paleozoic Era.The Ordovician spans 41.6 million years from the end of the Cambrian Period 485.4 million years ago (Mya) to the start of the Silurian Period 443.8 Mya..

The era began with a spectacular burst of new life. This is called the Cambrian explosion.The Paleozoic era is marked by an unprecedented boom of invertebrates and a subsequent spread of higher plants, fishes, and amphibians. Not only individual plant and animal groups, but also whole ecosystems developed, and still other new habitats were colonized.
