There have been (even recently) reports of strange animals in the amazon and the congo that sound a lot like dinosaurs. And there are reports of giant flying reptiles in Indonesia, and so forth.
There are thousands of square miles of almost impenetrable swamps and thick jungle in the world. Natives in some of these places describe beasts that fit with what just might be dinosaurs. And what about all the sightings of lake monsters?
This is a field called cryptozoology—the search for hidden animals. There just might be a few dinosaurs left, teetering on the edge of extinction. We are constantly discovering new species of animals and plants in remote areas. A tree can’t run away and hide and yet the Wollemi pine tree (said to have gone extinct millions of years ago) avoided detection until just recently.
When did dinosaurs exist? Some people would say, "Now."

Dinosaurs first appeared about 230 million years ago. The most recent dinosaur fossils seem to have been formed starting 65 million years ago.
So, 230 to 65 million years ago.

In the Moseozoic Era that is divided into 3 periods: Triassic, Jurassic and Cretaceous. The Triassic began about 250,000,000 years ago, and the Cretaceous ended about 65,000,000 years ago.

They existed over 4 Billion Years ago, during the Jurassic Period. You should look in your textbook; because there are so many periods during this time. Here are some to name a few: Cretacious Period, Jurassic Period, and Neolithic Period. During the Jurassic Period, dinosaurs such as the Tyranosaurus Rex emerged, as did the Stegosaurus, and Pterodactyl. If you watch the movie "Jurassic Park", you can see all these aforementioned dinosaurs in the movie.

I agree with the last answer - in a sense, they still exist amongst us, but as what we now call Birds...
