2,900,000,000 years ago,the Earth became pretty cold,and Glacier appeared on the Earth.（Additional information is available in the comments）

Additional information : Glacier is a form of water, it is snow transformation. Through a series of changes to form ice must first have a certain number of solid precipitation, including snow, fog, hail, etc. There is not enough solid precipitation as "raw material", means "bricks without straw", is simply not form ice. Ice exists in extremely cold places. The earth is at the age of cold in the arctic and Antarctic, in other regions can only glacial high altitude mountain. People know that the farther the lower the high temperature, when more than a certain height above sea level, the temperature will fall below 0 ℃, landing solid-state precipitation can be perennial. The altitude glaciologist called snow line .

Dinosaurs lived during the Mesozoic era, which ranged from 251 million years ago to 65 million years ago, beginning with the permian-triassic extinction event and ending with the cretaceous-tertiary extinction event, spanning 180 million years. The Mesozoic can be divided into the following three periods: Triassic period : 251 million years ago to 199.6 million years ago. Jurassic: 199.6 million years ago to 145.5 million years ago. Cretaceous : 145.5 million years ago to 65.5 million years ago.
