Despite the seemingly basic things we don't know about dinosaurs, we do know some surprising things – like their body temperatures.

**************

To learn more about this topic, start your googling with these keywords:

- Clumped Isotopes: heavy isotopes that are bonded to other heavy isotopes.

- Ectotherm: any animal whose regulation of body temperature depends on external sources.

- Endotherm: an animal that is dependent on or capable of the internal generation of heat.

- Isotope: each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular.

- Mesotherm: a type of animal with a thermoregulatory strategy intermediate to cold-blooded ectotherms and warm-blooded endotherms.

- Metabolism: the chemical processes that occur within a living organism in order to maintain life.
