The Cenozoic Era (66 million years ago through today) is the "Age of Mammals." Birds and mammals rose in prominence after the extinction of giant reptiles. Common Cenozoic fossils include cat …The late Paleozoic icehouse, also known as the Late Paleozoic Ice Age (LPIA) and formerly known as the Karoo ice age, was an ice age that began in the Late Devonian and ended in the Late Permian, occurring from 360 to 255 million years ago (Mya), and large land-based ice-sheets were then present on Earth's surface. It was the second major …

Era, a very long span of geological time; in formal usage, the second longest portion of geologic time after an eon. Ten eras are recognized by the International Union of Geological Sciences. An era is composed of one or more geological periods. The stratigraphic, or rock, term that corresponds to ‘era’ is ‘erathem.’.In the order of succession, the Palaeozoic era can be divided into six eras which are Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian eras. The Cambrian era lasted for 541 million years ago to 485.4 million years ago and is the first geological period of the Palaeozoic era.The paleozoic era is the earliest of three geologic eras of the Phanerozoic eon. This era spanned from roughly 542 million years ago to roughly 251 million years ago. The Paleozoic era is subdivided into six geologic periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.

Prehistory Paleozoic Paleogeographic reconstruction showing the Appalachian Basin area during the Middle Devonian period.. Michigan's fossil record stretches as far back as the Precambrian. Blue-green algae remains from this age were preserved between Copper Harbor and Eagle Harbor on the shoreline of Lake Superior. By the early part of the Paleozoic, Michigan was located in equatorial latitudes.The Paleozoic era is called “the cradle of ancient life.” Different types of plants and animals lived in both water and on land in this era. The fossil records of this era reflected the progression of different plants and animals. The fossils of first vertebrates appeared late in this era. Each era is again divided into periods. For example: Triassic, Jurassic and …The Paleozoic Era on the geological time scale is also known as the Primary Era or simply as the Paleozoic. It is the first era of the Phanerozoic Eon (which begins 541 million years ago and ends in our present days), which is followed by the Mesozoic and Cenozoic. It is also known as the “Age of Invertebrates”. ….

The temperature of a planet is linked with the diversity of life that it can support.
