65 million years ago
The modern era that began approximately 65 million years ago with the mass extinction of the dinosaurs is called the Cenozoic era. It is also known as the Age of Mammals, as mammals began to dominate the Earth during this time.
The mass extinction of dinosaurs were caused volcanoes that cause global warming with their toxic gases, therefore, killing the plants, starving the plant eating dinosaurs to death, and with no more plant eating dinosaurs, the meat eating dinosaurs died, too.
The formation of the ozone layer
During the Cenozoic era, which began around 66 million years ago, dinosaurs went extinct at the end of the previous Mesozoic era. Therefore, the existence of dinosaurs is something that did not occur during the Cenozoic era.
No dinosaur species survived the mass extinction event that occurred at the end of the Cretaceous period about 66 million years ago. However, birds are considered descendants of theropod dinosaurs and are the only living group of dinosaurs today.
The modern era that began approximately 65 million years ago with the mass extinction of the dinosaurs is called the Cenozoic Era.
In the Late Cretaceous (65 million years ago).
The dinosaurs fell victim to a mass extinction.
Cenozoic
The modern era that began approximately 65 million years ago with the mass extinction of the dinosaurs is called the Cenozoic era. It is also known as the Age of Mammals, as mammals began to dominate the Earth during this time.
Several periods of mass extinction
The mass extinction of dinosaurs were caused volcanoes that cause global warming with their toxic gases, therefore, killing the plants, starving the plant eating dinosaurs to death, and with no more plant eating dinosaurs, the meat eating dinosaurs died, too.
I think so.
No. The Jurassic was in the middle of the dinosaurs' reign on Earth. The time period after the extinction of the dinosaurs is referred to as the Paleogene or the Tertiary.
When the meteorite hit Earth and killed the dinosaurs.
The formation of the ozone layer
mass extinction of the dinosaurs. The impact caused widespread environmental changes, such as cold and darkness due to dust blocking the sun, leading to a disruption in the food chain and ultimately the extinction of many species, including the dinosaurs.
