Detailed explanation-1: -After the dinosaurs’ extinction, flowering plants dominated Earth, continuing a process that had started in the Cretaceous, and continue to do so today. But all land animals weighing over 25 kilogrammes died out. ‘What we’re left with are basically the seeds of what we have today.
Detailed explanation-2: -The end-Cretaceous extinction is best known of the “Big Five” because it was the end of all dinosaurs except birds (the non-avian dinosaurs). It also created opportunities for mammals. During the Mesozoic Era dinosaurs dominated all habitats on land.
Detailed explanation-3: -Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
Detailed explanation-4: -Following a mass extinction, biodiversity is greatly decreased, and it stays low during a “survival interval” before beginning to climb again. While some of the species that reappear after an extinction are new, others are pre-existing.
