Paleozoic Fossil Record. In the Paleozoic Era, plant and animal life began to develop greater range and complexity. Insects, reptiles, fish, and invertebrates advanced during this time, as well as vascular plant life. Cambrian exposures in Wyoming represent a transgressive depositional sequence (sandstones overlain by shale and limestone ...The Lower Paleozoic Era ended with the Ice Age, the temperature dropped, and a large number of species died. Later it was a period of stable weather, the weather was hot and humid, and there was a lot of carbon dioxide available in the atmosphere.Warm, shallow seas covered much of Earth's surface during early Paleozoic time. What covered most of Earth's surface at the beginning of the second era? Why is the earth covered in water?The Paleozoic era is represented by 47 minutes of the clock. In this era, plants and animals moved onto land and learned to co-exist. It is also the time when mass extinction happened and eliminated most of the species of life that existed. The Mesozoic Era. The Mesozoic era is represented by 29 minutes. In this era, plants and animals adapted to life on land. It is …the Palaeozoic, an era of arthropods, amphibians, fishes, and the first life on land; the Mesozoic, which spanned the rise, reign of reptiles, climactic extinction of the non-avian dinosaurs, the evolution of mammals and birds; and. the Cenozoic, which saw the rise of mammals. The Phanerozoic is divided into three eras: the Paleozoic, Mesozoic ...It is the earliest period in the Paleozoic ("old life") Era. Until relatively recently paleontologists thought this marked the beginning of life. Primitive life is now know from the Pre-Cambrian Eon.Eons are divided into eras, which are further divided into periods, epochs, and ages. Geologic dating is extremely imprecise. For example, although the date listed for the beginning of the Ordovician period is 485 million years ago, it is actually 485.4 with an uncertainty (plus or minus) of 1.9 million years.Paleozoic Era: Devonian. Back. In the course of the Devonian (from 416 to 360 million years ago) the largest Palaeozoic tropical reef in Europe appeared, ...At the end of the Paleozoic, about 250 million years ago, as many as 96% of species in the oceans became extinct. They didn't die all at once. It took over 8 million years for the mass extinction to wipe out all those species. This was the largest mass extinction of all time. Last modified June 1, 2005 by Lisa Gardiner.Cretaceous Period, in geologic time, the last of the three periods of the Mesozoic Era. The Cretaceous began 145.0 million years ago and ended 66 million years ago; it followed the Jurassic Period and was succeeded by the Paleogene Period (the first of the two periods into which the Tertiary Period was divided).The Paleozoic Era is composed of several periods: Cambrian Period. This Period that began approximately 542 Million years ago. It begins with the "Cambrian Explosion", an event that would change the history of life. Before the Cambrian, in the Ediacaric, life was reduced to simple and uncomplicated organisms, but in this "explosion" the ...The Paleozoic Era would see an explosion of variety of diverse life forms in the ocean, and eventually make the leap onto land.

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".Precambrian Eon. Precambrian is the general name for the geologic time period between when the Earth formed in the Solar System (in Hadean Time about 4.56 billion years ago) and the beginning of Phanerozoic Eon (about 540 million years ago). The oldest rock on Earth are Precambrian age. The Precambrian is subdivided into three Eons: • Hadean Eon (before about 4 billion years ago)The Paleozoic era is a period of time which was about 541 to 250 million years ago. The Paleozoic era is special in that the most rapid evolution of species happened here. The beginning of this period saw relatively simple lifeforms like trilobites and it ended with relatively more complicated lifeforms we know as the earliest dinosaurs.The Cenozoic Era is the most recent of the three major subdivisions of animal history. The other two are the Mesozoic and Paleozoic Eras. The Cenozoic spans only about 65 million years, from the end of the Cretaceous Period and the extinction of non-avian dinosaurs to the present. The Cenozoic is sometimes called the Age of Mammals, because the …The Paleozoic Era is a time period in Earth’s history that lasted from 541 to 252 million years ago. It is divided into six periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The Cambrian Period was the first period of the Paleozoic Era.
