Explore the age of the dinosaurs. Discover what the prehistoric world was like and how it changed between when dinosaurs first appeared and the mass extinction at the end of the Cretaceous Period. During this era, the land gradually split from one huge continent into smaller ones. The associated changes in the climate and vegetation affected how dinosaurs evolved. This meant that differences between animals or plants found in different areas were minor. Reptiles tend to flourish in hot climates because their skin is less porous than, for example, mammal skin, so it loses less water in the heat. Reptile kidneys are also better at conserving water.
Take a gander at what the Earth looked like at different points in history with this interactive 3D globe. Here's what our planet looked like over million years ago, according to the website Ancient Earth Globe. Ever wonder what the Earth looked like before humans came along and added pollution and man-made destruction to the mix? Seeing the Earth at various points in geological history, from million years ago to today, is an eye-opening activity to say the least. The website allows you to see the entire globe as it slowly rotates, or zoom in to see closer details of land and oceans.
Dinosaurs, as a group of animals, lived on Earth from to 65 million years ago, during the appeared and thrived, as did armored dinosaurs like "Stegosaurus. toward the end of this period and were among the very last dinosaurs alive.

All rights reserved. Visitors look at the skeleton of Tristan the Tyrannosaurus rex , one of the best-preserved large dinosaur skeletons, at the Natural History Museum in Berlin, Germany. In Jurassic World: Fallen Kingdom , humans are faced with a moral dilemma: Do we save the dinosaurs brought back to life by science when they are threatened by volcanic annihilation? Or do we let the dangerous beasts perish again? This made us wonder whether dinosaurs really could be resurrected, and if so, what would happen if we suddenly had to share the planet with these ancient animals.
What would have happened afterwards ó and how might their presence have affected mammals like us? It was the kind of cataclysm that we can scarcely imagine. When an asteroid 15km-wide nine miles slammed into planet Earth 66 million years ago, it struck with a force equivalent to about 10 billion Hiroshima bombs. A radioactive fireball seared everything for hundreds of miles in every direction and created tsunamis that sped halfway around the globe. Just as our ancestors had to deal with sabretooth cats, early humans would have had to deal with the dromaeosaurs and abelisaurs. But what if history had taken a different course?
A Scholastic Professional Book. Dinosaurs, as a group of animals, lived on Earth from to 65 million years ago, during the Mesozoic Era. They survived for an amazing million years. Why did these animals thrive? Paleontologists aren't sure, but it is clear that over time dinosaurs evolved and adapted to a variety of ecosystems ó living alongside insects, lizards, frogs, crocodiles, flying reptiles, birds, and mammals. The "Mesozoic Era" to 65 million years ago is so long that it's divided into three parts: The Triassic, Jurassic, and Cretaceous Periods. During this era, the world went through a series of slow but radical changes.

What Was the Dinosaurs' World Like?
What would happen if dinosaurs roamed the earth today? Answer by Ben Waggoner , Ph. D in Integrative Biology, paleontologist, and evolutionary biologist, on Quora :. Okay, first of all, one subgroup of dinosaurs is still roaming the Earth today: the birds. So dinosaurs poop on your car, visit your feeders, and feed you well on Thanksgiving.
