- The Mesozoic Era is the age of dinosaurs. They evolved from earlier reptiles to fill niches on land, in the water, and in the air.
- Mammals also evolved but were small in size.
- Flowering plants appeared for the first time.
- Dinosaurs went extinct at the end of the Mesozoic.

Which of geologic event occurred during the Mesozoic Era?
The era began in the wake of the Permian–Triassic extinction event , the largest well-documented mass extinction in Earth’s history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction which is known for having killed off non-avian dinosaurs, as well as other plant and animal species.
What happened during the end of the Mesozoic Era?
The Mesozoic came to an abrupt end 66 million years ago in a dramatic extinction event. An estimated 70 per cent of plant and animal species perished . ... The ‘catastrophists’ believe the mass extinction happened suddenly due to a meteorite impact.
What events happened during the Paleozoic Era?
Paleozoic Era, also spelled Palaeozoic, major interval of geologic time that began 541 million years ago with the Cambrian explosion , an extraordinary diversification of marine animals, and ended about 252 million years ago with the end-Permian extinction, the greatest extinction event in Earth history.
What is another name for the Mesozoic Era?
During the Mesozoic, or “Middle Life” era, life diversified rapidly and giant reptiles, dinosaurs and other monstrous beasts roamed the Earth. The period, which spans from about 252 million years ago to about 66 million years ago, was also known as the age of reptiles or the age of dinosaurs .
What are the 5 division of Mesozoic Era?
The major divisions of the Mesozoic Era are, from oldest to youngest, the Triassic Period, the Jurassic Period, and the Cretaceous Period . The ancestors of major plant and animal groups that exist today first appeared during the Mesozoic, but this era is best known as the time of the dinosaurs.
What are the three Mesozoic Era?
248 to 65 Million Years Ago
The Mesozoic is divided into three time periods: the Triassic (245-208 Million Years Ago) , the Jurassic (208-146 Million Years Ago), and the Cretaceous (146-65 Million Years Ago).
What era do we live in?
Officially, we live in the Meghalayan age (which began 4,200 years ago) of the Holocene epoch . The Holocene falls in the Quaternary period (2.6m years ago) of the Cenozoic era (66m) in the Phanerozoic eon (541m).
What are the 3 dinosaur periods?
Dinosaur communities were separated by both time and geography. The ‘Age of Dinosaurs’ (the Mesozoic Era) included three consecutive geologic time periods ( the Triassic, Jurassic, and Cretaceous Periods ). Different dinosaur species lived during each of these three periods.
What is the Cenozoic era known as?
The Cenozoic Era is the most recent of the three major subdivisions of animal history. The other two are the Mesozoic and Paleozoic Eras. ... The Cenozoic is sometimes called the Age of Mammals , because the largest land animals have been mammals during that time.
What was the weather like in the Mesozoic Era?
The Mesozoic Era was the time from 248 million to 65 million years ago. During the Mesozoic, the Earth was very different than it is now. The climate was warmer , the seasons were very mild, the sea level was higher, and there was no polar ice. ... Mesozoic means “Middle Animal” and is sometimes called the age of reptiles.
How long was the Paleozoic Era?
Paleozoic ( 541-252 million years ago ) means ‘ancient life. ‘ The oldest animals on Earth appeared just before the start of this era in the Ediacaran Period, but scientists had not yet discovered them when the geologic timescale was made.
What ended the dinosaur era?
Sixty-six million years ago, dinosaurs had the ultimate bad day. With a devastating asteroid impact , a reign that had lasted 180 million years was abruptly ended.
