The major geologic event in the Jurassic Period was the continuing breakup of Pangaea.

∙ 14y agothe Harland three-fold division of the Cretaceous into Neocomian, Gallic, and Senonian Epochs:
"Neocomian" division is based largely on climatic considerations. This "Early Early Cretaceous" demi-epoch was a time of steadily rising seas and temperatures.
The Early Late Cretaceous ("High Cretaceous") was marked by several critical events. The first was the widening Atlantic rift. The Atlantic Ocean: (a) had become wide enough to become a complete barrier to east-west dispersal over its entire length, except in the far north, and (b) was circulating meaningful amounts of ocean water north and south. The initial results seem somewhat paradoxical.
On the one hand, the High Cretaceous experienced unprecedented uniformity of ocean temperatures from pole to pole, suggesting very good horizontal mixing of ocean waters. On the other hand, it is well known for sporadic deep ocean anoxia, which would indicate poor vertical mixing.
Cretaceous Period (145.5 to 65.5 mya) :
- Period of Active Crust Plate Movements
- Africa and India separate from Antarctica (125 mya)
- Global warming event starts (120 mya)
Carbon dioxide levels were 550 to 590 ppm [27]
- Flowering plants (angiosperms) appeared
- Crocodiles appeared (110 mya)
- South America breaks away from Africa (105 mya)
- Formation of the Atlantic Ocean
- Earth has no polar ice
- Modern mammals and birds developed
- 100 mya: Earth's magnetic field is
3 times stronger than today.
- Global warming event ends (90 mya)
- 70 mya: Tyrannosaurus rex thrived
- 65 mya: Meteor impact, 170 km crater
Chicxulub, Yucatan, Mexico [9]
- 65 mya: Deccan Traps volcanic eruptions in India
produce great volume of lava and gases.
- * Mass extinction of 80-90% of marine species
and 85% of land species, including the dinosaurs

∙ 13y agoNo major geologic events I can recall took place during this time except a large mass of extinction. That is, if that's considered geologic.

Was era or period longer?
On the geologic time scale, an era is longer than a period. There are 12 geologic eras in total and they are composed of geologic periods. For instance, the Mesozoic era is composed of the Triassic, Jurassic and Cretaceous periods.
What geologic period was pangaea assembled?
Pangea was assembled in the late permian and broke up in the late triassic
Were there Plant during the triassic?
yes there were plants during this time period. there were trees
What were the major geologic events of devonian period?
there was plate tectonic movement
How was the Triassic period a transitional time period during the Mesozoic era?
I believe that dont know
Which came first the Jurassic or Triassic period of geologic time?
The Triassic preceded the Jurassic.
Which of the following is not a geologic period of the Earth Jurassic Cretaceous Triassic Neoprene?
Neoprene
Which geologic period gave rise to the climax of dinosaurs and ammonoids?
Dinosaurs and ammonoids appeared in the Triassic period.
What are the major geologic events in the triassic period?
Not much happened really except i think it was climate change and small dinos running around, the size of a chicken. (No im not kidding)

Pangea was assembled in the late permian and broke up in the late triassic
What time period did Pangea exist in?
Pangea existed in the Pennsylvanian, Permian, Triassic, and Jurassic periods of geologic time.
Did the thrinaxodon go extinct during the End Triassic extinction?
Thrinaxodon lived during the Triassic Period. They died out about 245 million years ago, at the end of the Olenekian portion of the Triassic period.
