What kind of dinosaurs were there in the cretaceous period?
The T-Rex and Triceratops. The extinction of the dinosaurs marked the end of the cretaceous period.
What appeared at the beginning of cretaceous period?
At the beginning of the Cretaceous period, around 145 million years ago, there was a significant diversification of dinosaurs, with many new species emerging. This period also saw the rise of flowering plants (angiosperms), which began to dominate terrestrial ecosystems. Additionally, marine life flourished, with the appearance of various mollusks, including belemnites and ammonites, and the presence of large marine reptiles. Overall, the Cretaceous marked a time of substantial evolutionary advancements and ecological changes.
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.
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.
How did dinosaurs change during the Cretaceous period?
No. If you count birds as dinosaurs, they still exist. If you don't, dinosaurs became extinct at the end of the Cretaceous, not the beginning.
What marked the end of the prehistoric period and the beginning of the historic period?
the invention of writing
What period was after the cretaceous?
The Paleogene Period followed the Cretaceous.
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?
jurassic The Triassic was the earliest period of the Mesozoic, followed by the Jurassic then the Cretaceous. The Cretaceous was of the greatest duration.
What Geological Period preceded the Jurassic Period?
after Jurrasic period it is the Cretaceous period
During which period the dinosaurs disappeared on the Earth?
The Cretaceous / Tertiary boundary (KT) occurred 65 million years ago and extinctions of most dinosaurs was probably due to a meteorite impact in the Yucutan peninsular of Mexico known as the Chixulub crater.
Did the K-T extinction occur before or during the Tertiary period?
The Tertiary Period (65.5 to 2.588Ma) is the informal name for the geological period that followed the K-T extinction event. So the K-T event happened before the Tertiary. In fact "K-T" is actually short for Cretaceous-Tertiary as it marked the end of the Cretaceous and the start of the Tertiary.The lower tertiary is more formally known as the Paleogene Period(65.5 - 23.03 Ma) and the upper Tertiary is more formally known as the Neogene Period(23.03 - 2.588Ma).
