Or warm blooded? What is the difference?

There is no way that we can be 100% certain if they were warm or cold blooded. Based on the paleontological evidence such as the structure of their bones, their rates of growth, evidence of feathers, etc. most paleontologists believe that at least some dinosaurs were warm blooded. Birds are warm blooded and if dinosaurs are, in fact, the ancestors of birds, then most likely dinosaurs (or at least those direct ancestors of birds) were warmblooded too.
"Warm blooded" and "cold blooded" are generally considered archaic as there are more than just the two methods of thermo-regulation. However, in gernal, "cold blooded" refers to an animal who's body temperature is not constant, whereas "warm blooded" animals maintain a constant body temperature.

Dinosaurs were cold blooded. The difference between warm and cold blooded is the temperature of blood inside the animal. Some are warm, some are cold.

As far as can be proven, it is showing as cold blooded, but there is some small evidence to say warm blooded. Cold blooded means the body does not naturally heat the blood and the body is the temperature of the air around it. Warm blooded means the body heats the blood and maintains it at a certain temperature.

Yes. They were cold blooded because they were related to reptiles. Now some were believed to be warm blood because they were related to a type of warm blooded animal.

The current theory is that most were neither, instead being gigantothermic. They were so big that the heat produced by their cellular activited was enough towarm the blood in their body cores. This is part of the reason why the sauropods have such big abdomens- more volume=warmer blood. The smaller ones were so active metabolically that they can be considered warm-blooded.

yes, as reptiles, dinosaurs were cold-blooded. this means that their bodies didnt produce al the heat necessary for their living and they had to stay in the sun to store some heat.
have you seen lizards standing in the sun? they are not sunbathing! :P
this is also one of the reasons why they think that dinosaurs disappeared after a huge meteorite crashed on earth and lifted tons and tons of dust that changed the climate for so many years hiding the sun from the dinosaurs

warm blooded ..difference is cold blooded animals need the sun to keep warm they store up the heat for nights coolness ..warm blooded animals produce their own heat

Yup, cold blooded. Warm blooded means that you can generate your own heat. That's why you see snakes lying in the sun, they are cold blooded and need the sun to warm them.

warm blooded. The difference is warm blooded is hot and cold blooded is not hot.

warm blooded animals can function independent of a heat source, cold blooded animals need to bask in the sun or some sort of heat source at least once a day
