What was the environment like?
How was the enviroment?
By the time in which those giant mammals lived, the climate in the region was drier and colder than nowadays. It was the “Ice Age”.
That cold climate had the consequence that the water, instead of filling the oceans, accumulated in the polar regions, forming extensive glaciers.
The lowering in the sea level made the coastline to be farther away than in the present, hence many localities, today submerged, were not near the coast.
