An asteroid impact
What does the end of the paleozoic and the mesozoic have in common?
Mass extinction
What era ended in the largest mass extinction in earth's history?
Mesozoic
Which eras ended with a mass extinction?
Two major eras that ended with mass extinctions are the Permian-Triassic extinction event, which marked the end of the Permian period, and the Cretaceous-Paleogene extinction event, which marked the end of the Cretaceous period. These events had profound impacts on life on Earth, leading to the loss of a significant number of species.
What era did organisms suffer largest mass extinction known?
Mesozoic era
The mass extinction at the end of the Mesozoic Era was caused by .?
a comet impacting the earth
What event marked the both the beginning and end of the Mesozoic era?
A mass extinction
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.
What event ended the paleozoic and mesozoic era?
Extinction did.
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 marks the division of the Paleozoic and mesozoic eras?
The Permian-Triassic mass extinction event marks the division between the Paleozoic and Mesozoic eras. This mass extinction, which occurred around 252 million years ago, resulted in the loss of about 90% of marine species and 70% of terrestrial vertebrate species.
