7 foot tall carnivorous Flightless Birds
What else can I help you with?
Did the cretaceous or permian extinction cause dinosaurs to become extinct?
No, as there was no Cretaceous-Permian extinction. There was the Permian-Triassic extinction, which ocurred before the dinosaurs appeared. Non-avian dinosaurs were wiped out in the Cretaceous-Paleogene extinction.
Most mammals during the Mesozoic were?
During the Mesozoic Era, most mammals were small, nocturnal, and likely insectivorous. They were overshadowed by larger reptiles like dinosaurs and did not become the dominant group of animals until after the extinction of the dinosaurs at the end of the Mesozoic.
The death of all the organisms of a species?
Extinct (Extinction)
What is extiction?
Extinction is where a species of a animal/plant totally dies out and there are none left, like Dinosaurs for example, or Dodos.
During which era did mammals become common?
Mammals became the dominant land animals in the early Paleocene period of the Cenozoic era, after the extinction of the non-avian dinosaurs at the end of the Cretaceous period of the Mesozoic era.
Which living organisms do not become extinct?
No species is immune to extinction. However, some species may have a lower risk of extinction due to factors such as adaptability, population size, and geographic distribution. Conservation efforts can also help to mitigate the risk of extinction for certain species.
Why did the trex become extincted?
Because there was a mass extinction and most living organisms died
True or false that most organisms that have ever lived on Earth are now extinct?
Yes. There have been several episodes of mass extinction. The worst was at the end of the Paleozoic era. The most famous came at the end of the Mesozoic, when the dinosaurs disappeared. Nature is cruel. Of course, some people say that species have not really become extinct, but merely evolved into different forms.
When were dinosaurs believe to have become extinct?
Dinosaurs became extinct along with many other types of ancient organisms in the K-T mass extinction that occurred 65 million years ago which probably coincided with an asteroid impact. This marked the end of the Mesozoic Era and the beginning of the Cenozoic.
Why were single-celled organisms dominant?
The reason single celled organisms were do dominant was because they were the least complex creatures. As single-celled organisms evolve into more complex creatures, their requirements also become more complex and it becomes harder for them to survive.
Why did trilobites become extinct?
The trilobites went extinct during the mass extinction at the end of the Permian period.
Why did the Archaeopteryx become extinct?
The cause of the extinction of Archaeopteryx is unknown to archaeologists. Their bones have been discovered since the 1860s and they appear to be easy prey for large dinosaurs.
