What would have happened if the ice age never ended?
With no cooling period leading up to the first ice age, grasses would not have spread so easily. There would be less variety, and the animals that evolved to eat grass would be less abundant. Horses, giraffes, cows, gazelles, any animal you associate with dry grasslands, would have had less habitat to flourish.
Were there any humans during the Ice Age?
The analysis showed there were humans in North America before, during and immediately after the peak of the last Ice Age. This significant expansion of humans during a warmer period seems to have played a role in the dramatic demise of large megafauna, including types of camels, horses and mammoths.
Did dinosaurs live during Ice Age?
Other than a few birds that were classified as dinosaurs, most notably the Titanis, there were no dinosaurs during the Pleistocene Epoch. They had become extinct at the end of the Cretaceous Period, more than 60 million years before the Pleistocene Epoch began.

What caused the end of the ice age?
Scientists have long known that ice ages are caused by variations in the earth’s orbit around the sun. When an intensification of sunlight initiates the end of an ice age, they believe, carbon dioxide is somehow flushed out of the ocean, causing a big amplification of the initial warming.
How cold was the last Ice Age?
The last great cold cycle, which we know as the Ice Age, ended about 10,000 years ago. During the Ice Age, the Earth’s average temperature was about 12 degrees Fahrenheit colder than it is today. That was enough to keep snow from melting during the summers in northern regions.
What happened during the last Ice Age?
The last ice age happened around 20,000 years ago. During an ice age, the whole planet is noticeably colder. Ice ages can last for million of years and help to shape continents. Today’s climate is actually a warm period between periods of glaciation.
Why did the Pleistocene extinctions occur?
Plants and animals were moving out of areas they had lived in and into new areas. Communities were coming apart and reorganizing. Many scientists think that these climatic and ecosystem changes caused the extinctions at the end of the Pleistocene.
