Transcript of Carboniferous Era

Carboniferous Era Pangea West half of Pangea was forming. When Pangea was forming, it created mountains such as the Rocky Mountains, the Ovachits mountain range, and the Appalachians. Animal Life- Pennsylvanian period Amniote egg was first created. This allowed for the arrival of birds, mammals, and reptiles. Earliest reptilia evolved from amphibians, known as Anapsids, which resemble lizards. Plant Life- Pennsylvanian Tropical plant life was lush, with forests of ferns, tree ferns, club mosses, horsetails, seed bearers. There were many tetrapods, detritavores, hexapods, herbivores, and winged insects. The Carboniferous era is split into two different periods: The Mississippian period and the Pennsylvanian period. Plant Life- Mississippian
There were many seeded plants that lived in drier habitats. There was also lycopsids, which was a club moss that lived in wet places.
The Mississippian period lasted from 360- 325 million years ago.
The Pennsylvanian period lasted from 325- 286 million years ago. Animal Life- Mississippian Period There were many fish, brachiopods, bryozoans, molluscs, echinoderms. There were also terrestrial tetrapods and winged insects. The Pennsylvanian period is known for its coal forming swamp forests that flourished during this period. It is also known for low-lying coastal regions. The Mississippian period is known for its large coal swamps. The Carboniferous era is actually named after the large coal swamps that formed during the Mississippian period. Climate- Mississippian As Gondwana continued to move across the South Pole during the Late Mississippian, temperatures cooled and ice began to form in great sheets.
As more water was frozen into these ice sheets, sea levels dropped and terrestrial habitats in turn increased. The globally warm climate became cooler later in the Mississippian. Climate- Pennsylvanian The middle of the continent was seasonally dry, and some of the changes in climate and vegetation recorded by fossils and rocks in North America and Europe probably reflect the movement of these areas from the warm, wet tropical belt into the seasonally dry subtropics. The world of that time was in an ice age, a generally cold global climate phase. Ice sheets were present at high latitudes, but the equator remained relatively wet and tropical for much of the period. Swamps dried out and many giant plants began to die out as the Pennsylvanian came to an end. The Earth was in a greenhouse climate state with relatively warm temperatures across a wide range of latitudes.
