What animals lived during the Pennsylvanian Period?

Life was abundant and diverse during the Pennsylvanian Period, both in the seas and especially on the land. Many of the marine limestone and shale, although only a few feet thick in most cases, contain abundant marine fossils of brachiopods, clams, snails, cephalopods, bryozoans, and rare trilobites, among others.

What plants lived during the Pennsylvanian Period?

Dominant plants included giant club mosses and horsetails, tree ferns, seed ferns and cordaites (conifer-like trees). Specimens of all but cordaites are displayed in this case. Late Pennsylvanian temperate forests were dominated by cordaites.

What organisms first appeared in the Pennsylvanian Period?

The first reptiles appeared during the Pennsylvanian Period. One of the earliest was the lizard-like Hylonomus, which was lightly built with deep, strong jaws and slender limbs. Several other major groups of reptiles appeared during the Pennsylvanian.

What happened in the Pennsylvanian time period?

Pennsylvanian Subperiod, second major interval of the Carboniferous Period, lasting from 323.2 million to 298.9 million years ago. The Pennsylvanian is recognized as a time of significant advance and retreat by shallow seas. Many nonmarine areas near the Equator became coal swamps during the Pennsylvanian.

What went extinct in the Pennsylvanian Period?

The lepospondylians became extinct during the Pennsylvanian subperiod. The development of the reptiles was characterized by the improvement of terrestrial reproductive systems during the Carboniferous, a feature not preservable in the record as such.

Why was the Pennsylvanian Period named?

The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. ... The current internationally used geologic timescale of the ICS gives the Mississippian and Pennsylvanian the rank of subperiods, subdivisions of the Carboniferous Period.

What types of plants Flora lived during the Carboniferous Period?

The plant life of the Carboniferous period was extensive and luxuriant, especially during the Pennsylvanian. It included ferns and fernlike trees; giant horsetails, called calamites; club mosses, or lycopods, such as Lepidodendron and Sigillaria; seed ferns; and cordaites, or primitive conifers.

What animals lived in the Silurian period?

Mollusks, bryozoans, and especially brachiopods flourished, but trilobites and graptolites were on the decline. Invertebrates remained dominant, vertebrate fossils are rare. Fish with moveable jaws appear, and the first bony fish (osteichthyans) evolved.

Was there an ice age during the Pennsylvanian Period?

About 30 percent of Pennsylvania was covered by glaciers during the Ice Age. It was a time when large sheets of moving ice blanketed the northern half of North America.

What came after the Pennsylvanian 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.

What did Earth's surface look like during the Pennsylvanian Period?

The Pennsylvanian Period lasted from 320 to 286 million years ago. During the Pennsylvanian Period, widespread swamps laid down the thick beds of dead plant material that today constitute most of the world's coal . ... From the bottom up, a typical sequence is sandstone , shale, coal, limestone , and sandstone again.

Where was North America during the Pennsylvanian Period?

During the Pennsylvanian period (323 -299 million years ago), what is now Kansas and the surrounding states was an ancient, tropical ocean located near the equator. An illustration of the ancient paleogeography of North America highlights the position of Kansas under a shallow sea and shows the nearby mountains.

What happened during the Mississippian Period?

During the Mississippian Period, shallow seas covered much of North America. ... This period is sometimes called the “Age of Crinoids” because the fossils of these invertebrates are major components of much Mississippian-age limestone. Also noteworthy in this period is the first appearance of amphibians.
