How Did the Dinosaurs Disappear?

You look up at a giant dinosaur skeleton and wonder how something so powerful could vanish.

Did every dinosaur suddenly die at the same time?

And how could one asteroid cause trouble across the entire planet?

The strange part is that it didn’t need to hit every dinosaur.

Something happened to the sunlight.

Then the plants began to struggle, food became scarce, and being enormous stopped being helpful.

But if all the dinosaurs disappeared, why are birds still here?

Maybe some dinosaurs never really left.
