The Ordovician period, around 485-443 million years ago, was characterized by a warmer climate with high sea levels and diverse marine life. It was a time of rapid evolution and diversification of marine organisms, including the first appearance of jawless fish. The atmosphere likely had higher levels of carbon dioxide compared to today.

What kind of atmosphere did the ordovician perid have?
The Ordovician Period had a warm and humid climate, with most landmasses clustered near the South Pole. The seas were filled with a diverse range of marine life, including early fish and invertebrates. The period ended with a mass extinction event that wiped out around 60% of marine genera.

Ordovician Period
What period did the formation of the oxygen atmosphere occur?
The formation of the oxygen atmosphere on Earth occurred about 2.4 billion years ago during the Great Oxidation Event in the Proterozoic Eon. This period marked a significant increase in atmospheric oxygen levels due to the photosynthetic activity of early cyanobacteria.

The Ordovician lasted for 47 million years from 490 to 443 Million Years Ago.
What is the dominant plant of the Ordovician period?
Algae was the dominant plant of the Ordovician. There were little to no other plants (other then algae) during the Ordovician. In the Ordovician, the common types of algae were Stromatolites (Blue green algae), and Tetradium (Red algae).
