Warm Blooded Versus Cold Blooded Dinosaurs

Scientists believe that warm blood and cold blood dinosaurs, as well as all dinosaurs, are cold-blooded animals. However, recently, it was discovered in 1993 that a dinosaur with a fossil heart was found in the northern part of Dakota, and many paleontologists began to think that some dinosaurs are warm blooded animals. Because dinosaurs are thought to be closely related to cold-blooded reptiles, people first think of dinosaurs as cold-blooded animals. Although cold blooded animals do not actually have "cold" blood, they rely on ambient temperature to regulate body temperature. They do this with exterters

As dinosaurs are considered reptiles, scientists believe that wild animals are as cold as their relatives. The slow metabolism of this cold-blooded dinosaur makes it awkward slowly in its ancient scenery. However, warm blood dinosaurs control body temperature, metabolism is fast. Such a big beast may be paralyzed near the house. Researchers have discussed the temperature regulation of dinosaurs for decades, but the new controversy began with the research of the Science Journal in 2014, stating that dinosaurs may be middle class. In fact, previous studies on dinosaur energy rates, energy expenditure, and teeth have also found evidence that they are warm blooded animals. Researchers say that the answer to this question will not only describe scientific journals but, in contrast, a more complete depiction of how dinosaurs survive and die.

Regardless of whether the dinosaur is "cold-blooded" isotherm, the use of the environment to regulate the internal temperature, or the endotherm of "hot-blood animals", regardless of whether the body temperature is regulated from the inside, this research is long-standing It occupied a rare middle point in the discussion. . "There is a third method," says John Grady, a biologist at Albuquerque University of New Mexico. Today, in the middle there are animals such as tuna, sharks, leatherback turtles. Grady says that researching how these organisms control body temperature might help to clarify the way dinosaurs were made millions years ago. Medium temperature burns energy from inside to regulate body temperature but does not reach a certain temperature like mammals and birds. For example, when the rate of metabolism declines, the tuna is 20 ° C warmer than the surrounding water unless it penetrates deeper into the cooler water.
