You are probably asking about the mass extinction at the Cretaceous-Mesozoic boundary, about 65 million years ago. We know that there was a major meteoric impact in the Yucatan peninsula at that time, which was at least partially involved in the mass extinction; some scientists believe that there were other contributing factors, but it remains a complicated and difficult issue to investigate.
What else can I help you with?
The mass extinction at the end of the Mesozoic Era was caused by .?
a comet impacting the earth
What event marked the end of the Mesozoic Ara and the beginning of the Cenozoic?
An asteroid impact
Which event marks the end of mesozoic era?
The end of the Mesozoic Era is marked by the mass extinction event that wiped out the dinosaurs, known as the Cretaceous–Paleogene extinction event. This event was likely caused by a combination of factors, including a meteorite impact and volcanic activity, and led to significant changes in Earth's ecosystems.
Precambrian Paleozoic Cenozoic Mesozoic what occurred just before the current era?
Just before the current era, which is the Cenozoic, the Mesozoic Era occurred. The Mesozoic, often called the "Age of Reptiles," lasted from about 252 to 66 million years ago and is characterized by the dominance of dinosaurs and the appearance of the first mammals and birds. It ended with a mass extinction event, likely caused by an asteroid impact, leading to the extinction of many species, including the dinosaurs. This transition paved the way for the rise of mammals and the eventual development of modern ecosystems in the Cenozoic Era.
Is the Cenozoic era before or after dinosaur extinction?
Yes, the Cambrian Period was before the Mesozoic Era
The mass extinction at the end of the Mesozoic Era was caused by .?
a comet impacting the earth
What event marked the end of the Mesozoic Ara and the beginning of the Cenozoic?
An asteroid impact
What era did organisms suffer largest mass extinction known?
Mesozoic era
What era ended in the largest mass extinction in earth's history?
Mesozoic
What event marked the both the beginning and end of the Mesozoic era?
A mass extinction
What era ended with a massive impact?
The Mesozoic era ended with a massive impact caused by an asteroid hitting Earth, leading to the extinction of the dinosaurs.
What type of reptile did not survive the mass extinction event at the end of the mesozoic era?
The non-avian dinosaurs did not survive the mass extinction event at the end of the Mesozoic era, known as the Cretaceous-Paleogene extinction event. These reptiles went extinct, paving the way for the rise of mammals and birds.
Which event marks the end of mesozoic era?
The end of the Mesozoic Era is marked by the mass extinction event that wiped out the dinosaurs, known as the Cretaceous–Paleogene extinction event. This event was likely caused by a combination of factors, including a meteorite impact and volcanic activity, and led to significant changes in Earth's ecosystems.
How might the mass extinction at the end of the mesozoic era relate to the dominance of mammals in the Cenozoic era?
mass extinction: When at least 50 % of the species on Earth go extinct within a relatively short amount of time.
What event ended the paleozoic and mesozoic era?
Extinction did.
Why did many planets die at the end of the mesozoic?
Scientists believe the Cretaceous-Paleogene extinction event, or the plants dying at the end of the Mesozoic Era, was caused by a massive asteroid/comet impact. The theory suggests that the impact had catastrophic effects on the environment, including an impact winter, which prevented the plants from carrying out photosynthesis.
What happened at the end of the Mesozoic era but did not happen at the end of the Paleozoic era?
There were major asteroid impacts.
