What was the average temperature of the Mesozoic era?

The average temperature of the Mesozoic era, which lasted from about 252 to 66 million years ago, is estimated to have been significantly warmer than today's climate, likely ranging from 15 to 25 degrees Celsius (59 to 77 degrees Fahrenheit). This era, characterized by a greenhouse climate, featured high levels of carbon dioxide and minimal polar ice. The warm temperatures supported diverse ecosystems, including lush forests and a variety of dinosaur species. Overall, the Mesozoic was marked by a generally warm and stable climate.
