Oxygen Levels were approximately 10% of what they are today. As photosynthesis only began in the Precambrian period the amount of carbon dioxide and oxygen in the atmosphere would be very small compared to modern times. In fact, human's probably wouldn't have been able to breath.
During the Cambrian period, the atmosphere was rich in oxygen, perhaps reaching levels as high as 30%, compared to the current 21%. The climate was generally warm and the Earth was predominantly covered in water, with a variety of marine life flourishing in the oceans. Land masses were just beginning to emerge, and simple multicellular life forms were evolving rapidly.

What is the index fossil of the Cambrian?
Trilobites are one of the index fossils commonly found in Cambrian rock layers. These ancient arthropods lived in the seas during the Cambrian period and are used by geologists as markers for dating rocks from that time period.
Where were most of the continents during the Cambrian period?
During the Cambrian period, known as the "Cambrian Explosion," most continents were part of a supercontinent called Gondwana, situated in the Southern Hemisphere. North America and Europe were closer to the equator at this time.
Was there oxygen in the Paleozoic Cambrian period?
Yes, there was oxygen present during the Paleozoic Cambrian period, but at much lower levels compared to today. Oxygen levels were still increasing during this time due to the evolution of photosynthetic organisms, like algae and early plants.
The cambrain period was part of this era?
The Cambrian period was part of the Paleozoic era. It occurred roughly 541 to 485 million years ago and is known for the rapid diversification of multicellular life forms, often referred to as the "Cambrian explosion."
How did the Cambrian period end?
The Cambrian period ended around 485 million years ago with an event known as the Cambrian-Ordovician extinction. This extinction event is believed to have been caused by changes in the Earth's climate and sea levels, as well as volcanic activity. It resulted in the loss of many marine species, paving the way for the rise of new organisms during the subsequent Ordovician period.
What period came after the Cambrian period?
The Ordovician period came after the Cambrian period.
What are some plants from the Cambrian period?
The only plant from the Cambrian period is algae.
What era did the Ediacaran Fauna Live?
The Ediacarian fauna are from the Cambrian Explosion. The Cambrian Explosion occurred in the Cambrian period. The Cambrian period was part of the Paleozoic era.
What was the climate like in the Cambrian period.?
generally warm, wet, and mild
What do the current landforms of the Cambrian period look like?
In the Cambrian period, the world's oceans were beginning to form because the glaciers were melting. Most of the world's land was in the Southern Hemisphere.
What languages were spoken in the Cambrian period?
There was no language used in the Cambrian period. Humans had not yet evolved.
Most common invertebrate in the Cambrian Period?
Haikouichthys and Myllokunmingia were two vertebrates in the Cambrian Period
What period did gastropods exist?
The Cambrian Period
What did earth's surface look like then during the Cambrian period?
it looked hot and spicy
The Cambrian period is also called the?
The Cambrian period is also called the "Cambrian explosion" due to the sudden appearance and diversification of many major animal groups.
What was before Triassic Period?
Carboniferous Silurian Ordovician Devonian Cambrian Pre Cambrian
Explosion of life what period?
Cambrian.
