What period did the dinosaurs become extinct?
Around the end of the Cretaceous Period.Dinosaurs became extinct at the end of the Mesozoic Era 65 million years ago. Their extinction also marked the beginning of the Cenozoic Era.Dinosaurs disappeared near the end of the cretaceous period.Most people believe it was at the end of the Cretaceous however the truth is that it ended in the Tertiary PERIOD not era so be careful that was why the event was called the K-T event because c had been taken in a mass extinction in the oceans.All non avian dinosaurs lived in the Mesozoic Era (251 - 65Ma). The mass extinction 65 million years ago of all non avian dinosaurs along with many other types of animals and plants marks the boundary between the Mesozoic and the Cenozoic Eras.
What future even might mark the end of the Cenozoic era?
The anticipated future event that might mark the end of the Cenozoic era is the possible onset of a new geological time period known as the Anthropocene. The Anthropocene represents a proposed epoch defined by significant influence of human activities on Earth's ecosystems and geology. The exact timing of the Anthropocene's beginning is still debated among scientists.
Which event marks the end of mesozoic era?
An asteroid impact
Why was the climate so eratic in the Cenozoic when it was so moderated in the Mesozoic?
During the Cenozoic, the Earth was cooling and sea levels were rising. The climate was moderated and warmer in the Mesozoic because of high carbon dioxide in the atmosphere. Before the Cenozoic Era, the earth was still quite warm and had some very wet conditions. The final breakup of Pangaea also occurred during this time evidence shows that there was change in oceans circulation. As a major event Antarctica broke away from Australia, it then moved over the South Pole. This caused the warm ocean current that had been flowing past Antarctic to be reversed. A cold current began to surround it. The climate of Antarctica cooled, and glaciers formed. With these massive changes in temperatures, land mass movement and changes in ocianic flow the environment became quite unstable.
What are mammals in mesozoic era?
Most mammals were much smaller than the dinosaurs and they were therefore better able to adapt to the conditions that brought the dinosaurs down. For example, a large dinosaur that ate vegetation would have died very soon if most vegetation was wiped out in a catastrophic event. Small mammals could still dig and forgage and make do with roots. It must have been horrific for everything alive at that time, but the very small creatures had the edge.

What happened at the end of both the mesozoic and palezoic eras?
There were major asteroid impacts. #fuckschool #imheretohelp
What event marks the division of the Paleozoic and mesozoic eras?
The event that marks the division of the Paleozoic and Mesozoic era is the breaking up of the Pangaea
How long ago did the 'paleozoic' era begin?
That would be 251 million years ago. The end of the Paleozoic era marks the beginning of the Mesozoic. The last period of the Paleozoic era was the Permian, and the first period of the Mesozoic era was the Triassic; hence the extinction event (the biggest extinction event in the earth's history), the Permian-Triassic extinction, which defines the border between the eras.

Was the mesozoic an mammal?
Mesozoic is a geological era, referring to the era lasting from around 250 million years ago up til about 65 million years ago. It is also sometimes called the Age of Reptiles because dinosaurs were the main animal at the time. This particular era includes the Triassic, Jurassic, and Cretaceous periods. Mesozoic basically translates as middle life, and is the era between the Paleozoic and Cenozoic eras of the Phanerozoic Eon. The Mesozoic era is centred between two mass extinctions, the Permian-Triassic event and the Cretaceous-Poleogene event. The Permian-Triassic event was the largest mass extinction in our world's history.
What future even might mark the end of the Cenozoic era?
The anticipated future event that might mark the end of the Cenozoic era is the possible onset of a new geological time period known as the Anthropocene. The Anthropocene represents a proposed epoch defined by significant influence of human activities on Earth's ecosystems and geology. The exact timing of the Anthropocene's beginning is still debated among scientists.
What marked the beginning of history?
There are many events that marked the start of a historical period. Perhaps the one with the most impact was the voyage of Christopher Columbus in 1492. The event marked the beginning of European development in the Western Hemisphere.
