Paleozoic Fish, arthropods, amphibians, reptiles, and synapsids all evolved during the Paleozoic. Life began in the ocean but eventually transitioned onto land, and by the late Paleozoic, it was dominated by various forms of organisms.

Suffragette Suffragist is a more general term for members of the suffrage movement. The term suffragette is particularly associated with activists in the British WSPU, led by Emmeline Pankhurst, who were influenced by Russian methods of protest such as hunger strikes.

Geological time scale The Ordovician and Cambrian Periods are referred to as the age of invertebrates, with trilobites abundant. In this period, brachiopods became more abundant that the trilobites, but all but one species of them are extinct today. In the Ordovician, large cephalopods developed as predators of size up to 10 meters.

The Paleozoic Era The Beginning Of An Explosion Of Life Forms The Paleozoic Era is the beginning of an explosion of life forms. The Cambrian Explosion marks the era with thousands of new life forms in the ancient seas. There was certainly life before the Cambrian Period. There were even many complex life forms. In late Precambrian time was a period called the Ediacaran. Ediacaran fossils are found in the Ediacaran Hills of Australia, Northwest Territories, Yukon, British Columbia, and Newfoundland in Canada.

Mesozoic Era: Age of the Dinosaurs Credit: Carl Buell. During the Mesozoic, or Middle Life Era, life diversified rapidly and giant reptiles, dinosaurs and other monstrous beasts roamed the Earth. The period, which spans from about 252 million years ago to about 66 million years ago, was also known as the age of reptiles or the age of dinosaurs. Boundaries

Ungulate Cladogram showing relations within Artiodactyla. As with many extant mammal groups, even-toed ungulates first appeared during the early Eocene (about 55 million years ago). In form, they were rather like today's chevrotains: small, short-legged creatures that ate leaves and the soft parts of plants.ladogram showing relations within Artiodactyla.

- Terrestrial life: Many arthropods, including eurypterids, arachnids (spiders and their kin) and primitive wingless insects invaded the land. Towards the end of the period the first fish-like tetrapods move ashore. Seed-bearing plants (Gymnosperms) also appeared during the latest Devonian.

Paleozoic Era The major divisions of the Paleozoic Era , from oldest to youngest , are the Cambrian ( 541 million to 485.4 million years ago ) , Ordovician ( 485.4 million to 443.8 million years ago ) , Silurian ( 443.8 million to 419.2 million years ago ) , Devonian ( 419.2 million to 358.9 million years ago ) , Carboniferous ( 358.9 million to 298.9 million ...

Paleozoic Era Flight was first achieved also during the Carboniferous Period as insects evolved wings. The Permian extinction, at the end of the Paleozoic Era, eliminated such major invertebrate groups as the blastoids (an extinct group of echinoderms related to the modern starfish and sea lilies), fusulinids, and trilobites.

Geology During the Paleozoic Era (300 to 500 million years ago), seas covered the region, leaving layers of marine sediment and the fossils of many types of marine animals. The present landscape was shaped between 5 million and 35 million years ago, during the Cenozoic Era.

Unit 8: The Paleozoic Era Paleogeographic Evolution of the continents during the Paleozoic. At the beginning of the early Paleozoic the continents were relatively close together. By the late Cambrian or early Ordovician they had separated into four continents: Laurentia, Baltica and Siberia in the north and Gondwanaland in the South.

Unit 1: Many Planets, One Earth // Section 7: Early Life: Single-Celled Organisms Throughout the Proterozoic era, from about 2.3 billion years ago until around 575 million years ago, life on Earth was mostly single-celled and small. Earth's biota consisted of bacteria, archaea, and eukaryotic algae. Food webs began to develop, with amoebas feeding on bacteria and algae.

- Unlike the other ancient eras, the Proterozoic Era contains good evidence of fossils which were mainly from archaeans and bacteria. This evidence is the proof that living organisms were in abundance in this era. The Era lasted from 2.5 billion years to 543 million years ago. Two major living organisms in existence of eukaryotic cells. At the mid of the Proterozoic Era there was an increase in the atmospheric oxygen.

- During the Ordovician Period, the surface of the earth was dramatically different than it is today. Nearly all life on earth was in the oceans. The only land life was in the form of very primitive plants very near the water line of the coasts, probably mosses and algae and were of a non-vascular nature.y the end of the Ordovician Period, primitive jawless fish called Ostracoderms appeared. These primitive fish were covered with bony plates and were among the first vertebrates on the earth.

The first tetrapods  land-living vertebrates  appeared during the Devonian, as did the first terrestrial arthropods, including wingless insects and the earliest arachnids.

Early vascular plants, collectively known as rhyniophytes, first appeared in the late Early Silurian and diversified considerably through the Late Silurian.rthropods are the most diverse group of animals on Earth and include insects, crustaceans, arachnids, myriapods, and onychophorans as well as extinct forms like trilobites. eurypterid. Any member of an extinct order (Eurypterida) of mostly aquatic, scorpion-like arthropods that were common in the early Paleozoic.
