The correct answer is (c) Mesozoic.
The Mesozoic Era, also known as the Age of Reptiles, was a geological era that lasted from about 252 to 66 million years ago. It was the middle of the Phanerozoic Eon and the third of the three eras of the Mesozoic Era. The Mesozoic Era was preceded by the Paleozoic Era and followed by the Cenozoic Era.
The Mesozoic Era is often referred to as the Age of Reptiles because reptiles were the dominant land animals during this time. Dinosaurs, pterosaurs, and crocodiles all evolved during the Mesozoic Era. The Mesozoic Era is also known for the mass extinction event that occurred at the end of the era, which wiped out most of the dinosaurs.
The Mesozoic Era is divided into three periods: the Triassic, Jurassic, and Cretaceous. The Triassic Period lasted from about 252 to 201 million years ago. The Jurassic Period lasted from about 201 to 145 million years ago. The Cretaceous Period lasted from about 145 to 66 million years ago.
The Triassic Period was a time of great change on Earth. The supercontinent Pangaea began to break up, and the first dinosaurs appeared. The Jurassic Period was a time of great diversity for dinosaurs. The first birds and mammals also appeared during this time. The Cretaceous Period was a time of great prosperity for dinosaurs. The first flowering plants appeared during this time, and dinosaurs reached their peak diversity.
The Mesozoic Era ended with the Cretaceous-Paleogene extinction event, which wiped out most of the dinosaurs. The cause of this extinction event is still debated, but it is thought to have been caused by a large asteroid impact.
The Mesozoic Era was a time of great change and diversity on Earth. The first dinosaurs appeared during this time, and they reached their peak diversity during the Cretaceous Period. The Mesozoic Era ended with the Cretaceous-Paleogene extinction event, which wiped out most of the dinosaurs.
