- Thick carbonate series of deposits formed at the end of each of the ice ages. One such rock unit, the Marinoan (aka Elatina), has been designated as the basement of the Ediacaran Period, that covered a time span of 635-542 million years ago, reaching a thickness of about 4 km.

Sponge Well-preserved fossil sponges from about 580 million years ago in the Ediacaran period have been found in the Doushantuo Formation. These fossils, which include spicules, pinacocytes, porocytes, archeocytes, sclerocytes and the internal cavity, have been classified as demosponges.

- The Ordovician Period. The Ordovician Period lasted almost 45 million years, beginning 488.3 million years ago and ending 443.7 million years ago.* During this period, the area north of the tropics was almost entirely ocean, and most of the world's land was collected into the southern supercontinent Gondwana.he Ordovician is best known for its diverse marine invertebrates, including graptolites, trilobites, brachiopods, and the conodonts (early vertebrates). A typical marine community consisted of these animals, plus red and green algae, primitive fish, cephalopods, corals, crinoids, and gastropods.

Silurian Period Facts: Climate, Animals & Plants The Silurian Period occurred from 443 million to 416 million years ago. It was the third period in the Paleozoic Era. It followed the Ordovician Period and preceded the Devonian Period. During this time, continental landmasses were low and sea levels were rising.

Ediacaran The Ediacaran Period, spans 94 million years from the end of the Cryogenian Period 635 million years ago, to the beginning of the Cambrian Period 541 Mya. It marks the end of the Proterozoic Eon, and the beginning of the Phanerozoic Eon. It is named after the Ediacara Hills of South Australia. The Ediacaran Period's status as an official geological period was ratified in 2004 by the International Union of Geological Sciences, making it the first new geological period declared in 120 years.

Geology chapter 19 The Devonian is a geologic period and system of the Paleozoic Era spanning from the end of the Silurian Period, about 419.2 ± 3.2 Mya (million years ago), to the beginning of the Carboniferous Period, about 358.9 ± 0.4. It is named after Devon, England, where rocks from this period were first studied.

Cambrian The Cambrian Period was the first geological period of the Paleozoic Era, of the Phanerozoic Eon. The Cambrian lasted 55.6 million years from the end of the preceding Ediacaran Period 541 million years ago to the beginning of the Ordovician Period 485.4 mya. Its subdivisions, and its base, are somewhat in flux. The period was established by Adam Sedgwick, who named it after Cambria, the Latinised form of Cymru, the Welsh name for Wales, where Britain's Cambrian rocks are best exposed. The Cambri

Precambrian Time Paleobiology It was some 4 billion years afterwards, with some exceptions, that animals first left their mark in the fossil record. But it was during this Precambrian period when profound events occurred, leading ultimately to life as we know it today. From 4500 to 3800 mya (the Hadean) the earth was indeed a hostile place. During this period the sun formed by gravitational compaction, and eventually reached the temperature and pressure conditions for nuclear fusion.

Ordovician Period This requires the latest version of Flash Player. Click here to download. During the Ordovician period, part of the Paleozoic era, a rich variety of marine life flourished in the vast seas and the first primitive plants began to appear on land—before the second largest mass extinction of all time ended the period.or the most part the Earth's climate was warm and wet, with sea levels rising as much as 1,970 feet (600 meters) above those of today. But once Gondwana took up its polar position in the late Ordovician, massive glaciers formed over Africa at the supercontinent's center.

Devonian Period The Devonian, part of the Paleozoic era, is otherwise known as the Age of Fishes, as it spawned a remarkable variety of fish. The most formidable of them were the armored placoderms, a group that first appeared during the Silurian with powerful jaws lined with bladelike plates that acted as teeth.ome Devonian trees are known to have grown 100 feet (30 meters) tall. By the end of the period the first ferns, horsetails, and seed plants had also appeared.

Shallow seas covering much of Gondwana became breeding grounds for new forms of trilobites. Many species of graptolites went extinct by the close of the period, but the first planktonic graptolites appeared.
