For more than 150 years, scientists have been debating on the body temperatures of dinosaurs and whether the body temperatures had an impact on their activity levels. Finally, it seems dinosaurs were somewhere in between hot and cold.
The new research reveals that dinosaurs had the capacity to increase the temperatures using natural sources like the sun.
Most of us know dinosaurs as they are depicted in the Jurassic series, but research by UCLA scientists is an indication that dinosaurs were probably not as fast as we know them to be, said a report on The Market Business.
For a long time, some scientists believed that dinosaurs could run fast as we know while others thought that they were almost same as modern-day alligators and crocodiles in terms of movements.
The researchers now believe that the dinosaurs were probably faster than these animals. Evidence was also found that some dinosaurs, on which the research was based, had temperatures that are lower than birds. It is also said that the dinosaurs were less active.
The research was first published in journal Nature Communications and has led by Robert Eagle. In the research, the experts worked with fossilized dinosaur eggshells found from Mongolia and Argentina.
The Argentine eggshells are around 80 million years old and belonged to the species known as sauropods that long characteristic necks.
On the other hand, the shells from Mongolia are approximately 75 million years old and from oviraptorid theropods. The smaller dinosaurs are known to have lower temperatures, especially the details from Mongolian shells.
