Devonian Precambrian Mesozoic Cenozoic Carboniferous and more.Long before people appeared on Earth , other forms of life existed. Many of these living things are now extinct, meaning they have died out completely. The period when they lived is called prehistory, or prehistoric times.The Quaternary Period (2.6 million years ago to the present) is composed of the Pleistocene and Holocene epochs. The Holocene Epoch began 11,700 years ago and continues into modern time. The vast interval of time that spans Earth’s geologic history is known as geologic time. It began roughly 4.6 billion years ago when Earth began to form …

The Paleozoic Era is divided into the Cambrian, Ordovician, Silurian, Devonian, and Carboniferous periods, each with characteristic groups of fossils. The Cambrian Period saw the explosion of new kinds of invertebrate animals in the oceans, including trilobites (Figure 2), primitive kinds of shellfish, including brachiopods and molluscs, and other groups of …The Devonian period is a geological interval in the Paleozoic Era that spans between the Silurian and the Carboniferous. It marks the first transition of vascular plants and certain animals from ...During the Paleozoic Era (541 to 252 million years ago) Fish diversified and marine organisms were very abundant during the Paleozoic. Common Paleozoic fossils include trilobites and cephalopods such as squid, as well as insects and ferns. The greatest mass extinction in Earth's history ended this era.

It is also known as the age of dinosaurs. It lasted from 245 to 65 million years ago and is divided into the three periods described in Figure below. The Mesozoic began with the supercontinent Pangaea. Then, during the era, Pangaea broke up and the continents drifted apart.The Ordovician System rounded out the threefold division of early Paleozoic rocks (i.e., Cambrian, Ordovician, and Silurian), which are all named for Welsh tribes. Recognizing the Ordovician between the Cambrian and Silurian ended a 40-year controversy, eliminated an “overlapping system,” and created a new interval of time in its own right.Throughout the Palaeozoic era, about 540 to 250 million years ago, plants colonized land and rapidly diversified.

The heavily armored fish from the Devonian became extinct, being replaced with more modern-looking fish fauna. Though many spectacular plant forms dominated the Carboniferous, most of them disappeared before the end of the Paleozoic.For the Paleozoic era ... The development of simple plant life in the ocean was critical to the formation of an atmosphere that contained oxygen. Starting about 2.4 billion years ago, oxygen was released from the seas as a by-product of photosynthesis by cyanobacteria (Figure 1). Oxygen levels slowly rose, reaching the current level by about ...Video transcript. The Earth is now starting to get closer to being hospitable to people like us or animals like us. In the last video, we saw during the Proterozoic Eon, oxygen began to accumulate in the atmosphere. This actually caused this first snowball Earth and this mass extinction of all the anaerobic species.
