During the Mesozoic era, which lasted from about 252 to 66 million years ago, the atmosphere was characterized by higher levels of carbon dioxide, approximately 1000 to 2000 ppm (parts per million) compared to current levels of around 400 ppm. Oxygen levels were also higher, ranging from 26% to 30% compared to the current 21%.

How the amount of oxygen in the atmosphere gradually increased?
The amount of oxygen in Earth's atmosphere increased gradually over millions of years due to the process of photosynthesis by early bacteria and later by plants. These organisms released oxygen as a byproduct, which accumulated in the atmosphere and changed its composition over time. This process, known as the Great Oxidation Event, occurred around 2.4 billion years ago and significantly increased the amount of oxygen in the atmosphere.
