The Quaternary Period. 2.6 million to 11,700 years ago.
At the end of Tertiary period the layout of landmasses was almost as we see them today (the continents and countries). This period is the fourth great age of Planet Earth.
This period on earth is also called the 'Pleistocene Period' or 'Ice-Age'. This is because 2.6 million years ago the climate began to significantly cool and polar ice caps formed and grew, spreading across the Earth's service. This was not one single event, rather events that happened several times in the last 2.6 million years.
There have been 11 major cold (glacial) events recognised in the last 2.6 million years with warming episodes in between, like the one we are in currently.
In the cold times, iconic large mammals, like the woolly mammoth roamed around the edge of the ice sheets on the frozen tundra here in the Black Country.
We have artefacts on display showing this period including a sabre-tooth cat, small scale woolly mammoth and real mammoth tusks.
