The Earth was much warmer due to increased carbon dioxide levels (sea-surface temperatures in the tropics were at an incredible 95 degrees Fahrenheit, for example), and the world’s oceans were a staggering 558 feet higher than they are today. Estimates suggest that Cretaceous Antarctica had a climate similar to today’s Italian peninsula and was filled with plant and animal life, including dinosaurs.

I'd like to see the data that supports those claims.

Exactly. We know CO2 doesn’t cause ‘warming’. It’s a lagging indicator of warming. Correlation, not cause.

I am not sure about the temperatures but during the Cretaceous, there were no ice caps and an inland ocean extended from Texas up to Canada. Lots of chalk deposits and such. Rivers flowed east into it from the ancestral Rockies. Many of these sands from the rivers and their deltas produce oil and gas now.

Part of the evidence consists of fossils we’ve dug up. Tree and herbivorous dinosaur fossils in Antarctica, marine fossils in the Great Basin of the United States.

When I lived in New Mexico I found petrified tree stumps in the middle of the desert, miles from any water, and the Indian Pueblos were evacuated because of a massive drought, they believe.
