Why didn't the ozone layer protect the dinosaur's?
The ozone layer only formed about 600 million years ago when there was already a diverse array of life on Earth.

What is the length in millions of years of the Tertiary period?
The answer is 63.2 million years. Since the Tertiary Period began 65 million years ago and then stoped 1.8 million years ago you have to subtract the 1.8 million from 65 million to get the actual lenght of time.

The meteorite-impact hypothesis proposes that the extinction of the dinosaurs was caused by a large asteroid striking the Earth approximately 66 million years ago. This impact led to massive environmental changes, including huge amounts of dust blocking sunlight and causing a "nuclear winter" effect, which disrupted the food chain and ultimately led to the extinction of many species, including the dinosaurs.
