The Carboniferous Period has been divided into the Lower Carboniferous (Mississippian) and the Upper Carboniferous (Pennsylvanian) based on the differing stratigraphy found on different continents. The Mississippian has a stratigraphy that was mostly limestone, and most coal-bearing deposits (not all) were found in the Pennsylvanian.
What else can I help you with?
How long did the pennsylvanian period last?
The Pennsylvanian Period was from about 325 million to 280 million years ago. It is part of the Paleozoic Era. The Pennsylvanian and the Mississippian (345 to 325 MYA) are often grouped together as the Carboniferous Period.
What is Mississippian period?
The Mississippian period was a cultural, social, and economic era in pre-Columbian North America, lasting from around 800 to 1600 AD. It was characterized by the development of complex societies, large-scale agriculture, and chiefdoms, centered around the Mississippi River Valley region. Mississippian cultures are known for their earthen mounds, extensive trade networks, and distinctive pottery styles.
Does an outcrop containing Jurassic dinosaur fossils overlying Pennsylvanian coal deposits represent uninterrupted deposition?
No, the outcrop does not represent uninterrupted deposition. The presence of Pennsylvanian coal deposits indicates a gap in time between the deposition of the coal and the Jurassic dinosaur fossils, suggesting a period of erosion or non-deposition between the two.
What was volcanic activity like in the Pennsylvanian time period?
During the Pennsylvanian time period, there was a lot of volcanic activity and these constituted a lot of rock formation. Volcanic ashes also settled on the earth's surface and buried some trees.
When was redwall limestone formed?
Redwall limestone was formed during the Mississippian period of the Paleozoic era, approximately 340 million years ago. It is a prominent feature in the Grand Canyon region of the United States.
What is the Mississippian and Pennsylvanian periods grouped together?
The Mississippian and Pennsylvanian periods are grouped together as the Carboniferous period. This period lasted from approximately 358.9 million to 298.9 million years ago and is known for the widespread deposition of coal-forming swamps.
What are the Pennsylvanian and mississippian periods called together?
The Pennsylvanian and Mississippian periods can be best explained by the carboniferous system which is divided into a number of sections. The division came from the North America stratigraphy.
Is the mississippian period in paleozoic era?
Yes. The Mississippian period is a part of the Paleozoic era, along with the Cambrian, Ordovician, Silurian, Devonian, Pennsylvanian, and Permian periods.
Carboniferous period was subdivided into what two periods?
The Carboniferous period is subdivided into the Mississippian and the Pennsylvanian periods.
How long did the pennsylvanian period last?
The Pennsylvanian Period was from about 325 million to 280 million years ago. It is part of the Paleozoic Era. The Pennsylvanian and the Mississippian (345 to 325 MYA) are often grouped together as the Carboniferous Period.
What happened 544-245 million years ago?
The Paleozoic Era began. Development of fish amphibians, insects and reptiles. Cambrian Period Ordovician period Silurian Period. Devonian Period Mississippian Period Pennsylvanian Period Permian Period
Why are pennysylvanians and mississppians Periods named after the US states?
The Pennsylvanian and Mississippian are sub divisions of the Carboniferous Period and in North America comprise marine limestones, while in Europe (where the Carboniferous was first described), the equivalent rocks form one more-or-less continuous sequence of lowland continental deposits. The Pennsylvanian and Mississippian are therefore worthy of separate description and are named after the US states in which they have their greatest outcrops.
What geologic ages were Athyris alive?
Athyris was a genus of brachiopods that existed during the Carboniferous Period, specifically in the Mississippian and Pennsylvanian epochs. This places Athyris in the geologic ages of the Carboniferous Period, which lasted from approximately 359 to 299 million years ago.
Period during which source of great coal deposits in West Virginia Pennsylvania Ohio and Illinois existed?
pennsylvanian period
What is Mississippian period?
The Mississippian period was a cultural, social, and economic era in pre-Columbian North America, lasting from around 800 to 1600 AD. It was characterized by the development of complex societies, large-scale agriculture, and chiefdoms, centered around the Mississippi River Valley region. Mississippian cultures are known for their earthen mounds, extensive trade networks, and distinctive pottery styles.
When did the Pennsylvanian period start?
I have no clue.
What was the dominant reptile in the Pennsylvanian period?
bicth
