Are reptiles considered cold blooded?
Most reptiles today are cold-blooded, meaning their body temperature is determined by how warm or cold their surroundings are. So, when they found reptile teeth with different oxygen signatures, it probably meant that those reptiles had warmer body temperatures than the fish did.
What causes a reptile to be cold blooded?
Nothing causes a reptile to be “cold blooded”. It refers to how they metabolize energy. Officially, they are called ectothermic, which means that they generate their body heat through outside sources. This allows them to go long periods between eating.

In other words, their bodies remain at the same temperature as their immediate surroundings. The term DOES NOT imply that an animal is cold to the touch.
How does a reptile keep its body temperature?
Reptiles are cold-blooded, or ectothermic, animals. This means that they cannot produce heat in their own bodies, and have to rely on their surroundings to keep warm. By moving in and out of sunlight, reptiles can keep their body temperature at a steady level throughout the day.
