The carbon dioxide (CO2) levels in the Cretaceous were 1,700 parts per million. That is 6 times the modern pre-industrial level (the amount of CO2 before the industrial revolution). The higher CO2 levels may have been partially responsible for the warm average temperature during the Cretaceous (4 C [7.6 F] above modern temperature).
During the Cretaceous period, which lasted from approximately 145 to 66 million years ago, carbon dioxide levels in the atmosphere were estimated to be significantly higher than today, possibly exceeding 1000 parts per million (ppm). This elevated CO2 concentration is believed to have contributed to a much warmer climate during that time.

What period came first Jurassic cretaceous or triassic?
The Triassic period came first, followed by the Jurassic period, and then the Cretaceous period.
Last period of mesozoic period?
Cretaceous
What came after the Jurassic period?
The Jurassic period was followed by the Cretaceous period in the Mesozoic era. The Cretaceous period lasted from around 145 to 66 million years ago and ended with a mass extinction event that led to the disappearance of dinosaurs.
How was the cretaceous period different from the Jurassic period?
The Cretaceous period followed the Jurassic period and lasted from about 145 million to 66 million years ago. In the Cretaceous period, flowering plants became more dominant, dinosaurs continued to diversify, and large marine reptiles like mosasaurs thrived. However, the end of the Cretaceous period marked by a mass extinction event where dinosaurs and many other species went extinct.
Dinosaurs died in what geological period?
Dinosaurs died in the Cretaceous period, around 66 million years ago, in an event known as the Cretaceous-Paleogene extinction event.
Does the air have more or less carbon dioxide in it?
CO2 levels in the atmosphere have been rising since the start of the Industrial Revolution. i t depends. Note that the CO2 levels of Earth's atmosphere have varied considerably over the course of its existence. For example: CO2 levels during the Cretaceous period are estimated to have been about 6 times what they are right now.
What period was after the cretaceous?
The period after the Cretaceous is the Paleogene period, which is part of the Cenozoic era. It includes the Paleocene, Eocene, and Oligocene epochs.
Were there there fruits in the cretaceous period if so which kind of fruits?
There were a fruit in the cretaceous period. There were berries in this period.
What period came first Jurassic cretaceous or triassic?
The Triassic period came first, followed by the Jurassic period, and then the Cretaceous period.
What Geological Period preceded the Jurassic Period?
The Triassic Period preceded the Jurassic Period in the geologic timescale.
Were there fruits in the cretaceous period if so which kind of fruits?
There were fruits in the cretaceous period. There were berries and bread in this period.
In what period did the Triceratops live?
Triceratops lived in the late cretaceous period.
Which period is older than the Triassic period?
The Jurassic Period followed the Triassic.
The Cretaceous period was a part of what era?
The Cretaceous period was part of the Mesozoic era.
Last period of mesozoic period?
Cretaceous
Did the dinosaurs died at the end of the cretaceous Jurassic or triassic period?
Cretaceous.
What period did the spinosaurus live in?
Spinosaurus fossils have been found in Morocco and Egypt, and they date to between 112 and 97 million years ago. This was during the Albian and Cenemonian stages of the Cretaceous period, which was the third and final period of the Mesozoic era.
