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.

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, in fact oxygen level in the pre-cambrian reach high enough levels to allow multi-cellular life.
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.
Is where trilobites and brachiopods appeared?
Trilobites first appeared in the fossil record in the Atdabanian stage of the Early Cambrian period. The fist brachiopods likewise first appeared in the Early Cambrian era.
What was the atmosphere like during the Jurassic period?
During the Jurassic period, the atmosphere was warmer and had higher levels of oxygen compared to today. There were lush forests with a diverse range of plant and animal species, including dinosaurs and early mammals. The climate was relatively stable and supported the evolution of many iconic prehistoric creatures.
What are some plants from the Cambrian period?
The only plant from the Cambrian period is algae.

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?

What is the time period era Cambrian where hard shelled fossils appeared?
The Cambrian period, which lasted from approximately 541 million years ago to 485 million years ago, is known for the sudden appearance of diverse hard-shelled fossils. This period marked the rapid diversification of marine life and the emergence of many new forms of life in Earth's oceans.
What was before Triassic Period?
