1 Answer. We live in the Holocene Epoch, of the Quaternary Period, in the Cenozoic Era (of the Phanerozoic Eon).
Q. Who survived the Devonian extinction?
Although freshwater fish were barely affected, marine animals were much more so. Placoderms, for example, did not survive, acanthodians were decimated, and almost all agnathans vanished. Numerous brachiopods became extinct, conodonts all but disappeared, and only one family of trilobites survived.

Q. When did the Devonian period start and end?
419.2 (+/- 3.2) million years ago – 358.9 (+/- 0.4) million years ago
Q. When did the Carboniferous period start and end?
358.9 (+/- 0.4) million years ago – 298.9 (+/- 0.15) million years ago
Q. What ended the Pennsylvanian Period?
The end of the Pennsylvanian Period was marked by a dry climate, the gradual disappearance of the vast coastal coal swamps and changes in plants and animals. These changes were brought about by the assemblage of the super-continent, Pangaea, and retreat of the shallow seas from interior continental areas.
Q. What came after the Carboniferous Period?
Carboniferous Period, fifth interval of the Paleozoic Era, succeeding the Devonian Period and preceding the Permian Period. In terms of absolute time, the Carboniferous Period began approximately 358.9 million years ago and ended 298.9 million years ago.
Q. When did the Carboniferous period start?
358.9 (+/- 0.4) million years ago
Q. What animals existed during the Carboniferous Period?
Land animals included primitive amphibians, reptiles (which first appeared in the Upper Carboniferous), spiders, millipedes, land snails, scorpions, enormous dragonflies, and more than 800 kinds of cockroaches.
Q. Why were there so many plants in the Carboniferous period?
The shallow seas became swamps between the ocean and the dry land. New plants developed in the warm, humid climate and swampy conditions of this period. Large trees covered with bark and huge ferns grew in the middle Carboniferous swamps. The plants gave off so much oxygen that the air had much more oxygen in it.
Q. What did Earth look like during the Carboniferous Period?
Early in the Carboniferous Period, Earth’s climate was warm. Later, glaciers formed at the poles, while equatorial regions were often warm and humid. Earth’s climate became similar to today’s, shifting between glacial and interglacial periods.
Q. When did the first dinosaur appear on Earth?
230 million years ago
Q. How long did the Permian period last?
The Permian period lasted from 299 to 251 million years ago* and was the last period of the Paleozoic Era. The distinction between the Paleozoic and the Mesozoic is made at the end of the Permian in recognition of the largest mass extinction recorded in the history of life on Earth.
Q. What event started the Permian period?
The Permian period, which ended in the largest mass extinction the Earth has ever known, began about 299 million years ago. The emerging supercontinent of Pangaea presented severe extremes of climate and environment due to its vast size. The south was cold and arid, with much of the region frozen under ice caps.
Q. What was the Earth like before Pangea?
Many people have heard of Pangaea, the supercontinent that included all continents on Earth and began to break up about 175 million years ago. But before Pangaea, Earth’s landmasses ripped apart and smashed back together to form supercontinents repeatedly.
Q. What animals existed during Pangea?
Pangaea existed for 100 million years, and during that time period several animals flourished, including the Traversodontidae, a family of plant-eating animals that includes the ancestors of mammals. During the Permian period, insects such as beetles and dragonflies flourished.
