What separates the Mississippian period from the Pennsylvanian period?
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.
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.

Today's fossil fuels began forming about 300 million years ago in pennsylvanian period. what was most likely true about that time period?
During the Pennsylvanian period, Earth's landmasses were consolidated into the supercontinent Pangea. The climate was warm and humid, leading to extensive swamp forests that eventually formed the coal deposits we extract as fossil fuels today. The period was characterized by the diversification of early reptiles and the emergence of the first insects to fly.

Did dinosaurs roam the lands during the pennsylvanian period?
No, dinosaurs did not roam the lands during the Pennsylvanian Period. The Pennsylvanian Period occurred from approximately 323 to 298 million years ago, while dinosaurs first appeared much later in the Triassic Period, around 230 million years ago. During the Pennsylvanian Period, the dominant land animals were early amphibians and reptiles, along with a diverse array of plant life.
When did cockroaches first appear?
Actually they were from the Pennsylvanian Period and the Paleozoic Era...
What lived during the Pennsylvanian Period?
There are several things that lived during the Pennsylvanian Period. Giant water scorpions, eels, crocodiles, newts, salamanders, and many other things lived during this time.
How did the Pennsylvanian era start?
The Pennsylvanian period began around 323 million years ago during the Carboniferous period. It is characterized by the abundant growth of ferns, amphibians, and early reptiles, leading to the formation of extensive coal swamps. The Pennsylvanian era was a time of significant environmental and evolutionary changes.
What separates the Mississippian period from the Pennsylvanian period?
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 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.
During what period did the insects first appear?
Silurian Period 408 - 438 Million Years Ago
