What order (from oldest to most recent) are Jurassic cretaceous Permian Triassic and Cambrian?
The correct order from oldest to most recent is Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, and Cretaceous. The Cambrian period marks the beginning of the Paleozoic Era, while the Cretaceous period is the last of the Mesozoic Era. The Permian and Triassic periods follow the Paleozoic and precede the Mesozoic, with the Jurassic and Cretaceous periods occurring afterward.

Which was NOT a subdivision of the Mesozoic era?
The Cenozoic era was not a subdivision of the Mesozoic era. The Mesozoic era is subdivided into the Triassic, Jurassic, and Cretaceous periods.
What are all the periods for all the eras?
Paleozoic Era: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian. Mesozoic Era: Triassic, Jurassic, Cretaceous. Cenozoic Era: Paleogene (Paleocene, Eocene, Oligocene), Neogene (Miocene, Pliocene), Quaternary (Pleistocene, Holocene).
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 phanerozoic periods in order?
The Phanerozoic Eon is divided into three major eras: the Paleozoic Era, the Mesozoic Era, and the Cenozoic Era. The Paleozoic Era is further divided into six periods: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The Mesozoic Era is divided into three periods: Triassic, Jurassic, and Cretaceous. The Cenozoic Era is divided into two periods: Paleogene and Neogene.
Why is the boundary between the Triassic and Jurassic periods is similar to the boundary between the Permian and Triassic periods?
The boundary between the Triassic and Jurassic periods, like the boundary between the Permian and Triassic periods, is marked by significant geological and biological changes, including mass extinctions and the emergence of new life forms. Both transitions signify major shifts in Earth's ecosystems, with the end of dominant species and the rise of new ones in response to environmental changes. Additionally, these boundaries are characterized by distinct rock layers and fossil records that indicate significant climatic and ecological transformations.
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 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
Which was NOT a subdivision of the Mesozoic era?
The Cenozoic era was not a subdivision of the Mesozoic era. The Mesozoic era is subdivided into the Triassic, Jurassic, and Cretaceous periods.
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.
What are all the periods for all the eras?
Paleozoic Era: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian. Mesozoic Era: Triassic, Jurassic, Cretaceous. Cenozoic Era: Paleogene (Paleocene, Eocene, Oligocene), Neogene (Miocene, Pliocene), Quaternary (Pleistocene, Holocene).
What is The Oldest Period in the Mesozoic Era?
The oldest period in the Mesozoic Era is the Triassic period, lasting from about 251 to 201 million years ago. It followed the Permian mass extinction and saw the early diversification of dinosaurs, as well as the first appearance of mammals and birds.
What are 3 facts about the mesozoic era?
The Mesozoic Era spanned from approximately 252 million years ago to 66 million years ago. Dinosaurs evolved and dominated the Earth during this era, with a wide variety of different species. The Mesozoic Era ended with a mass extinction event that wiped out the dinosaurs, believed to have been caused by a meteor impact.
When did the three mass extiintion happen?
The three mass extinctions referred to are the Permian-Triassic extinction about 252 million years ago, the Triassic-Jurassic extinction about 201 million years ago, and the Cretaceous-Paleogene extinction about 66 million years ago.
After precambrian time what are the two basic divisions of the geologic time scale?
The two basic divisions following the Precambrian on the geologic time scale are the Paleozoic Era and the Mesozoic Era. These eras are further divided into periods, such as the Cambrian, Devonian, and Permian in the Paleozoic Era, and the Triassic, Jurassic, and Cretaceous in the Mesozoic Era.

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 are the common abbreviations for the geologic time periods?
