What is the Mississippian and Pennsylvanian periods grouped together?
The Carboniferous Period
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.
Carboniferous period was subdivided into what two periods?
Mesozoic era and Cenozoic Era
What are the geologic periods named from?
Most geologic periods are named for the location where rock formations were first found that contained fossils from that period, some others (e.g. Carboniferous) were named for materials associated with the fossils.
What are the different era?
Modern dating techniques have given a range of dates as to when the various geologic time periods have started, as they are listed below: Cenozoic Quaternary Holocene 10,000 years ago Estimated millions of years: Pleistocene 1.9 Tertiary Pliocene 6 Miocene 25 Oligocene 38 Eocene 55 Paleocene 65 Mesozoic Cretaceous 135 Jurassic 200 Triassic 250 Paleozoic Permian 285 Carboniferous (divided into 350 Mississippian and Pennsylvanian periods by some in the U.S.) Devonian 410 Silurian 425 Ordovician 500 Cambrian 570 Precambrian Proterozoic 2500 Archeozoic 3800 Azoic 4600

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 are the periods that divide the early paleozoic?
Devonian, Carboniferous and Permian Periods
What dinosaur periods where there?
The main dinosaur periods were the Triassic, Jurassic and Cretaceous periods. they were in the mesozoic era. there were other periods before dinosaurs like the carboniferous.
What period did the continents move together to form Pangaea?
Pangaea came together over a period of time spanning the Carboniferous and Permian periods. It broke up mostly during the Jurassic period.
Carboniferous period was subdivided into what two periods?
Mesozoic era and Cenozoic Era
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.
What are the time periods of the paleozoic era?
From youngest to oldest: 1. Permian 2. Pennsylvanian 3. Mississippian 4. Devonian 5. Silurian 6. Ordovician 7. Cambrian
When did the first frog appear on earth?
They first appeared during the late Carboniferous/ early Permian periods, Paleozoic
What were some of the periods included in the paleozoic era?
The periods are... 1. Cambrian 2. Ordovician 3. Silurian 4. Devonian 5. Carboniferous 6. Permian -You owe me big time!
How many periods are in each era?
there are different periods in each era. In the Cenozoic era, there are 2 periods, Quaternary and Tertiary. Mesozoic era has 3 periods, Cretaceous, Jurassic, and Triassic. Paleozoic has 7 periods, Permian, Carboniferous, Devonian, Silurian, Ordovician, and Cambrian. Precambrian is just the present, no time periods in it.
