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
After the Triassic period, the Jurassic period began, followed by the Cretaceous.
It was part of 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.

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 time periods' names are spelled Cretaceous and Jurassic, respectively. The Cretaceous period was longer, lasting more than 75 million years.
They all lived during the Cretaceous period.
