In accordance with the arrangement and shape of its teeth, scientists know that the long-necked dinosaur Brachiosaurus has a temperature of 38.2 degrees centigrade and Camarasaurus a smaller stature has a temperature of about 36.8 degrees centigrade.Apparently, they are nearly the same temperature with a man who had an average of 37 degrees C. Similarly, as quoted by The Straits Times, (Friday, 24/06/2011).
The discovery was immediately reported online in the journal Science. It does not take the time to debate whether dinasaurus modern warm-blooded like mammals or coldblooded like a lizard. When they were first discovered, there is a theory which states that they are sluggish and cold-blooded, but in recent years, consensus has been moved and said that dinosaurs were more toward warm-blooded, allowing them to become more active, such as the Velociraptors in Jurassic Park.
"Our analysis enables us completely rule out the theory that they are cold-blooded like a crocodile," said lead investigator Robert A. Eagle, of the California Institute of Technology.
"This does not mean dinosaurs have a high metabolism like mammals and birds, they have 'gigantotherms and keep warm because they are so big," he added
Meanwhile, Thomas Tuetken from the University of Bonn states that a body mass of the giant animals are very good in keeping the temperature constant.
The researchers explain that the animal that has a great body can maintain its body heat even with a relatively low metabolism.
Branchiosaurus weighs 36 tons, while the Camarasaurus have a lighter weight is 13.6 tons. Both allegedly lived approximately 150 million years ago.
