Amazing Dinosaur Facts: Just How Many Were There?

All animals need warmth inside their bodies to stay alive. But did dinosaurs make their own body heat like people do—or did they depend on the sun, like lizards?

It’s one of the biggest mysteries scientists are still trying to solve!

Warm-Blooded vs. Cold-Blooded

Warm-blooded animals—like dogs, birds, and humans—can keep their bodies warm even when it’s chilly outside. Their temperature stays steady, whether it’s hot or cold.

Cold-blooded animals—like snakes and lizards—need sunlight or warm air to heat up. If it’s cold outside, they get cold too and may become slow or sleepy.

So what about dinosaurs?

What Do Scientists Think?

Some scientists believe dinosaurs were warm-blooded, especially because birds (who came from dinosaurs) are warm-blooded today. That would mean dinosaurs could run, move, and hunt even when the weather changed.

But other scientists think dinosaurs were cold-blooded, more like reptiles. That would mean they needed sunlight and warm air to stay active.

The truth is, we don’t know for sure yet! Dinosaur fossils don’t tell us everything, and scientists are still searching for clues.
