Dinosaur Body Temperatures and Adaptations

The video explores the mysteries of dinosaurs, focusing on how scientists determine their body temperatures. Despite being extinct, researchers use bioapetite in bones and teeth to measure temperatures, revealing that dinosaurs had varying body temperatures. The video explains the debate between endothermy and ectothermy and how isotopes help infer temperatures. It highlights the adaptability of dinosaurs like Troodon, which could adjust its body temperature. The video concludes with a promotion for Tab for a Cause, a browser extension supporting charity.

What is one thing we surprisingly know about dinosaurs despite many uncertainties?

• Their mating rituals

• Their body temperatures

• Their extinction cause

• Their diet

What mineral helps scientists measure dinosaur body temperatures?

• Gypsum

• Bioapetite

• Calcite

How do heavy isotopes behave in warmer temperatures?

• They bond more frequently

• They bond less frequently

• They dissolve

• They evaporate

What is the term for animals that generate heat internally?

• Endothermy

• Exothermy

• Ectothermy

• Thermotherapy

Which dinosaur had a body temperature of 38 degrees Celsius?
