Scientists of Adelaide University, Australia, has denied allegations that dinosaurs were the cold-blooded. The argument, if they cold-blooded, then this beast will not have the muscle strength needed to prey on other animals and can not compete with the similiar size mammals, as they did over 80 million years.

At today school lessons, they believe the idea that dinosaurs behaved like the saltwater crocodile, which is cold-blooded. Professor Roger Seymour from Adelaide University's School of Earth and Environmental Sciences, observe how much muscle strength can be produced by crocodiles or dinosaurs than the similiar-sized mammals.
"At 200 kilograms, the crocodile is only producing 14 percent the energy that a similar-sized mammal would produce," he said. Animals have always been soaking in the sun all day.
Seymour and his team of researchers from Monash University, University of California, and the Wildlife Management International researched and measured blood and muscle lactate (compound) of crocodile that weighs 200 kg. They analyzed a sample of the great reptiles.
According to Seymour, large dinosaurs could do the same and enjoy the warm body temperature. "Without generate their own heat in the cells through energy-burning foods such as warm-blooded animals," he said further.
Dinosaur that lived during the Mesozoic period, between 252 and 66 million years ago. The famous species are tyrannosaurus rex, stegosaurus and brontosaurus. They are more dominating than the terrestrial ecosystem mammals throughout this period.
It shows that the animal has a large size, such as a crocodile resembling a dinosaur warm-blooded animals. "The results further show that cold-blooded crocodiles lack not only the absolute power for exercise, but also the endurance evident in warm-blooded mammals," he said. "If you imagine a fight between a crocodile-like dinosaur and a mammal-like dinosaur, it's clear that the mammal-like dinosaur would win."
Seymour also said the latest evidence of his research on blood flow to the leg bones of dinosaurs. His findings reveal that dinosaurs may even be more active than the mammals. The research has now been published in the scientific journal PLoS ONE. *** [EKA | FROM VARIOUS SOURCES | DAILYMAIL | ROSALINA | KORAN TEMPO 4296]
