What happened to the Earth during the Cambrian period?

The Cambrian period, part of the Paleozoic era, produced the most intense burst of evolution ever known. The Cambrian Explosion saw an incredible diversity of life emerge, including many major animal groups alive today. Among them were the chordates, to which vertebrates (animals with backbones) such as humans belong.

What was Earth like in the Cambrian period?

Climate of the Cambrian Period In the early Cambrian, Earth was generally cold but was gradually warming as the glaciers of the late Proterozoic Eon receded. Tectonic evidence suggests that the single supercontinent Rodinia broke apart and by the early to mid-Cambrian there were two continents.

Where was life on Earth found in the Cambrian era?

The best-known of these sites is the legendary Burgess Shale (middle Cambrian) in the British Columbian Rocky Mountains. Sites in Utah, southern China, Siberia, and north Greenland are also noted for their unusually good preservation of non-mineralized fossils from the Cambrian.

What era is the Cambrian period in?

PaleozoicCambrian / EraThe Paleozoic Era is the earliest of three geologic eras of the Phanerozoic Eon.

What era did life move on land?

The conventional viewpoint is that the first terrestrial life migrated out of the water about 430 million years ago, in the midst of a period known as the “Cambrian Explosion of Life”–an evolutionary heyday when favorable conditions allowed life to swell and branch into most of the major forms in existence today.
