According to a new research scientists can find out the body temperatures of ancient dinosaurs by examining the fossilized eggs they left behind. After applying the latest research technique, scientists at UCLA said that ancient eggs have shown that some species were sufficiently warm-blooded to roam around much more quickly as compared to modern gators.

The latest method is based on an in-depth scientific understanding of how the formation of eggshells takes place. The temperature at which the formation of shells of calcium carbonate takes place affects the organization of certain carbon isotopes.

Researchers succeeded in analyzing correlations between carbon isotopes in egg shells and the internal body temperatures of bird and reptile species. This is because biology of formation of egg in modern birds and reptiles is majorly similar to what it was in egg-laying dinosaurs millions of years back.

When researchers came to know that they have created a formula that rightly predicted the temperature of the animals from which the eggs belonged to, they applied their science to fossilized dinosaur eggs.

They found that the formation of eggs of long-necked sauropod dinosaurs took place at temperatures of nearly 100 degrees Fahrenheit. Eggs laid by smaller theropods known as oviraptors formed at approximately 90 degrees Fahrenheit.

Geologic evidence has suggested that the dinosaurs' body temps were a little warmer as compared to their climate's average temperature of 79 degrees Fahrenheit.

"This technique tells you about the internal body temperature of the female dinosaur when she was ovulating," explains study co-author Aradhna Tripati, a UCLA assistant professor of geology, geobiology and geochemistry. "This presents the first direct measurements of theropod body temperatures."
