Cambrian Period By: connor macey & chet albert

Trilobites were the dominant species during the Cambrian Period, 540 to 490 million years ago.

During Cambrian, there were essentially no polar or high-altitude glaciers

The Cambrian period lasted about 53 million years

During most of Cambrian, global sea levels were at relatively high elevations as compared with most of the balance of Earth's history.

Cambrian global climate ultimately became warmer than today.

This Period is the first geological time period of the Paleozoic Era

The world's continents were mainly low-lying deserts and alluvial plains.

When the bizarre animal was first discovered in the Burgess shale of the Canadian Rocky Mountains, scientists couldn't tell its head from its tail.

The Cambrian explosion was when life ¨exploded¨

541 million years ago in the Cambrian period, during which most major animal phyla appeared.

That is when the Cambrian explosion happened

The Cambrian explosion or Cambrian radiation was the relatively short evolutionary event

The Cambrian period was named in 1835 by the geologist Adam Sedqwick, after the region of Cambria in Southern Wales and England.

The name "Cambria" is a version of Cumbria, which is a latinisation of the Welsh word "Cymry" meaning countryman, or compatriot against the invading Anglo-Saxon tribes.
