1.) mammals,amphibians,crocodiles,turtles,insects,and land plants survived the cretaceous time.
2.) 1815 was called the year without summer because the volcanic dust, propelled into the stratosphere where it couldn't get rain, sunlight.
3.) Not only was iridium common in the last Cretaceous layers, but also microtektites, which are small glass spheres characteristic of the impact of an asteroid with terrestrial rocks that contain silicon. Shocked quartz grains, characteristic of powerful impacts, were also found.
4.) All this happened, even though the global temperature decreased by only about 2°F (1½12;°C).
5.) The Cretaceous extinction changed the face of biodiversity on Earth. After the large dinosaurs were gone, many large mammals evolved as well as many small ones.
6.) The lower part of the Cretaceous System consists of six stages: the Berriasian, Valanginian, Hauterivian, Barremian, Aptian, and Albian.
7.) Early Cretaceous characteristically deltaic and lacustrine.
8.) Late Cretaceous including marine deposits, such as sandstone and the characteristic chalk, a pure fine-grained white limestone formed largely of planktonic coccoliths.
9.) As continents continued to drift apart, the climate over much of the land became cooler and drier during the Cretaceous.
10.) plants appeared, and dinosaurs and other reptiles reached their peak of development.after Jurrasic period it is the Cretaceous period
It was part of the Mesozoic Era.
Neoprene is not a geologic period of the Earth. The Jurassic, Cretaceous, and Triassic are all recognized geologic periods that represent different intervals of time in the Earth's history.
The Cretaceous period occurred approximately 145 to 66 million years ago.
Cretaceous limestone is a type of sedimentary rock formed during the Cretaceous period, approximately 145 to 66 million years ago. It is made up of predominantly calcium carbonate minerals derived from the remains of marine organisms such as corals, shells, and algae. Cretaceous limestone is often used as a building material and in the production of cement.
Early humans first appeared in the tertiary period, a long time after the cretaceous period.
The Cretaceous Period was the longest period of time.

The Jurassic Period followed the Triassic.
Tyrannosaurus lived during the Cretaceous Period.
A time period of the ancient Earth which had very stable climate
The Jurassic Period is longer than the Cretaceous Period. The Jurassic Period lasted from around 201 to 145 million years ago, while the Cretaceous Period lasted from around 145 to 66 million years ago.

They all lived during the Cretaceous period.
The Paleogene Period followed the Cretaceous.
