Were dinosaurs warm-blooded or cold-blooded?

What means �warm-blooded�? What means cold-blooded? Which animal is warm-blooded? Which animal is cold-blooded? Where of it�s been get the energy to keep warm the body of animals? When oxygen combines with a combustible material (that material get combusted), it results heat. Mitochondrion is an organelle, which is inside animals� body cells. Oxygen and combustible material (food) are combined inside mitochondria. In other words, foods are burning gradually inside mitochondria such burning results heat. Animals use this heat to keep warm their body. As more food burns inside cell, more heat (as it�s equal) produces, and animals� body warms better. To generate more heat enough amount of oxygen and food must be forwarded to body cells. The work forwarding oxygen and food to cells is the responsibility of circulatory system. If circulatory system be strong and advanced, it can forward oxygen and enough food to cells which generates more heat, there by temperature of animals� body will be high (warm-blood animal). On the contrary, if circulatory system be weak, less oxygen and necessary food will be forwarded to cells and the generated heat will be slight, so the temperature of body, will be low (cold-blood animal). Even, in cold-blood animals too, temperature of body is several degrees more than environment temperature, but because they have weak circulatory system, so they can�t warm their body further. The gravity of earth is one of the factors that influence the strong of circulatory system. If the gravity be low, then the power of circulatory system will be higher and vice versa. Reptiles have 3-chambered heart. At the present time which gravity is high, the power of such animal�s circulatory system is too low to can forward oxygen and enough food to body cells. Therefore the present reptiles are cold-blooded. But in the past, being the gravity low, the same existing circulatory system of retails, had the enough power forwarding oxygen and enough food to cells. So, ancient retails (dinosaurs) were warm-blood. By gradually increasing the gravity, the power of their circulatory system has been decreased and the heat of their body has been decreased too.
Keith Wilson: Ramin (below) states that dinosaurs were reptiles and so could only have had 3 chambered hearts. This cannot now be known. I tend to the belief that dinosaurs were warm blooded, that birds were an off spring of dinosaurs and so likely dinosaurs had four chambered hearts. In fact, if they were like the Bar Head Geese they had a more efficient blood pumping system and oxygen efficiency units than mammals have today.

Ramin: Dinosaurs had 3-chamber hearts, but they were warm blood, not cold blood! Why? Because the gravity was low (in dinosaurs� time) and 3-chamberd heart could achieve enough blood (feed and oxygen) to the cells of tissues (body), and it made the body to be warm blooded. Birds and mammals have derivated from reptiles. At the present time, because the gravity has been increased, so to cater enough blood to cell of the body, the need to a 4-chambered heart (stronger heart). Present time, 3-chamberd heart has not the enough power to keep the animals to be warm, but it has in the past. Initial (primary) 4-chamberd heart has been created in reptiles� (dinosaurs�) body which birds and mammals have been derivated from them. So it is not an astonishing matter seeing dinosaurs with primary 4-chamberd heart. Now you can see primary 4-chamberd heart, in today living crocodile�s body. So crocodile has the largest body between today living reptiles.

Keith Wilson: How can we be certain that dinosaurs were "reptiles" with "3 chambered" hearts? Reptiles have out facing legs (even crocodiles) Dinosaurs had down facing legs and sockets (like mammals and birds). Also, we can't know that dinosaurs had a 3 chambered heart. It could be that Dinosaurs were not reptiles and had 4 chambered hearts and still your theory would be valid. Thus, how can you be so certain dinosaurs were both reptiles and had a 3 chambered heart?

Ramin: The characteristic that puts an animal in a class of reptiles or mammals, it is not being out facing legs or down facing legs. The skeleton of reptiles and mammals has some differences with each other that by them it's possible to recognize fossils of animals. One of these important characteristics is three small bones of middle ear, which are available for mammals but not for reptiles. In all of zoology books, dinosaurs are put in reptiles� class, because their skeletons are similar to reptiles completely. The reptiles have 3-chambered heart, so dinosaurs (which belong to reptiles class) had 3-chambered heart. This is logical form point of view of evolution process. But why scientists try to present dinosaurs� heart as 4-chambered? Because they have some paradox about gravity. They want to solve this problem (high gravity) by presenting dinosaurs hearts to be 4-chambered. The fossil used for this theory is absolutely an incomplete fossil.(I have it's article). It's impossible to judge for all kinds of dinosaurs bosed on that certain fossil. Some times scientists to solve this problem (high gravity), design multi-heart for dinosaurs, even eight heart. We must not to supply power dinos' heart, but we must decrease gravity. In such conditions the problem will be solved completely. Q: Why dinos (past reptiles) were down facing legs, but the present reptiles are out facing legs? A: Because gravity were low in the past and they could keep their body in stood mode. But now the gravity is high and it has pasted their body to the ground. Mammals will be changed to out facing legs by increasing the gravity gradually in the future too. (See a walrus and a seal).
Neal Adams: A gator or other reptile living at the equator has the exact same weather.

Ramin: Animals with large body (including all classes), (the greatest birds, the greatest mammals, the greatest reptiles and greatest other classes) live near equator, because gravity of that point is lower than other point of earth.
Mike Clark: Cold blooded animals eat food once a week like snakes, crocodiles, and other reptiles, they are heated by the Sun. They have a lower metabolism. Warm blooded animals require more food to maintain their body's at a higher temperature, so they eat many times per week. They have a higher metabolism.

Ramin: When the blood circulation system is weak, and couldn�t to forward the food beside the oxygen to cells (to be combinated there), in this care the animal ought to eat less food because the previous food is still unused.
