What are the five stages of how pangaea has thought to have evolved?
they are Permian, Triassic, Jurassic, Cretaceous, and today
Did the Cambrian Period come after the Jurassic Period?
No the Cambrian Period came before the Jurassic Period.Periods in the Paleozoic Era (542 - 251 Ma) and the Mesozoic Era (251 - 65.5 Ma)Cambrian (542 - 488.3 Ma)Ordivician (488.3 - 443.7 Ma)Silurian (443.7 - 416 Ma)Devonian (416 - 359.2 Ma)Carboniferous (359.2 - 299 Ma)Permian (299 - 251 Ma)Triassic (251 - 199.6 Ma)Jurrasic (199.6 - 145.5 Ma)Cretaceous (145.5 - 65.5 Ma)
What period is sometimes called the golden age of trilobites?
Trilobites, amphibians, and many other species of animals became extinct in the Permian-Triassic extinction. This event happened over 250 million years ago.
What list places the divisions of the geologic time scale in order from longest to shortest?
The order of geologic time from smallest to largest is Phanerozoic, Proterozoic, Archean and Hadean (Deep Time). These four periods are called Eons which can be further subdivided into Eras, Periods and Epochs. Most people are more familiar with the periods such as Cambrian, Permian, Triassic, Jurassic and. Cretaceous and many more to numerous to mention. To learn more, Google geologic time scale.
What is geolgic time?
Earth's history is divided into apparent major climate changes, usually delineated by mass extinctions. The previous three periods are the paleozoic, mesozoic, and Cenozoic. The paleozoic is further divided into the Cambrian, vendian, orodovician, silurian, devonian, mississipian, pennsylvanian, and permian. I remember the order with the mnemonic: Campbell's Very Ordinary Soups Do Make People Puke. The mesozoic is divided into the triassic, Jurassic, and cretaceous. The cretaceous ended 65 million years ago. The most recent division (ours) of the Cenozoic is the holocene. Before that, the pleistocene. Othere cenes are miocene, pliocene, oligocene, and paleocene. These are in no particular order--I need to find a good mnemonic for them.

The major divisions in geologic time are?
Precambrian Paleozoic: -cambrian -ordovician -silurian -devonian -mississippian -pennsylvanian -permian Mezozoic: -triassic -jurassic -cretaceous Cenozoic: -tertiary -quaternary
What are the major subdivisions of geologic times?
The major subdivisions are the Precambrian, Palaeozoic, Mesozoic and Cenozoic, which are subdivided into Archean and Proterozoic (Precambrian), Cambrian, Ordovician, Silurian, Devonian, Carboniferous (or Missisipian and Pennsylvanian in the US) and Permian (Palaeozoic), Triassic, Jurassic and Cretaceous (Mesozoic) and Tertiary and Quaternary (Cenozoic).

What are 3 facts about the mesozoic era?
1) Pangea begun to break apart during this period. 2) Dinosaurs began to evolve during the Triassic Period. 3) The joining and separating of the continents affected which kinds of dinosaurs lived where.
What are the areas on the geologic time scale?
Paleozoic Era- Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian Mass Extinction (Permian-Tertiary) 248 mya Mesozoic Era- Triassic, Jurassic, Cretaceous Mass Extinction (K-T) 65 mya Cenozoic- Tertiary, Quaternary
Did the cretaceous or permian extinction cause dinosaurs to become extinct?
No, as there was no Cretaceous-Permian extinction. There was the Permian-Triassic extinction, which ocurred before the dinosaurs appeared. Non-avian dinosaurs were wiped out in the Cretaceous-Paleogene extinction.
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.
What are the common abbreviations for the geologic time periods?
Cambrian-Barred capitol "C" Ordivician-"O" Silurian-"S" Devonian-"D" Carboniferous-"C" Permian-"P" Triassic-"T" Jurassic-"J" Cretaceous-"K" due to the German translation "Kreide" meaning chalk Paleogene-"Pg" Neogene-"N"
Did the Cambrian Period come after the Jurassic Period?
No the Cambrian Period came before the Jurassic Period.Periods in the Paleozoic Era (542 - 251 Ma) and the Mesozoic Era (251 - 65.5 Ma)Cambrian (542 - 488.3 Ma)Ordivician (488.3 - 443.7 Ma)Silurian (443.7 - 416 Ma)Devonian (416 - 359.2 Ma)Carboniferous (359.2 - 299 Ma)Permian (299 - 251 Ma)Triassic (251 - 199.6 Ma)Jurrasic (199.6 - 145.5 Ma)Cretaceous (145.5 - 65.5 Ma)

What are the 7 periods that species have roamed on earth?
The earliest period when amphibious creatures crawled out of the ocean to walk on land would have been the Devonian Period. Following that were the Carboniferous, Permian, Triassic, Jurassic, Cretaceous,Tertiary and Quaternary Periods.
What time period did Pangea exist in?
Pangea existed during the late Paleozoic and early Mesozoic eras, approximately 300-175 million years ago. This supercontinent began to break apart around 175 million years ago, leading to the formation of the continents as we know them today.
