dinosaur,still exists?

Birds are dinosuars! Researchers believe they evolved from the dinosaur! I am surpised you didn't know that! Sharks,crocodiles,alligators and turtles are also from that time period. They aren't related to the dinosaur but they have been around since that time! Sharks and those other animals were alot bigger back then they are today!

Yeah sure but they may not same with what are they in the past, they may evolved to some thing diferent, and they may be resized

If there is, I hope the poor thing stays well hidden. Being 'discovered' by man is a surefire route to extinction.

many times, each year again, there are still "new" animals found. Animals people never knew they exist or thought they were not there anymore. I doubt if the big dinosaur are still there since the world they lived in was completely different from ours. All the animals you see now started with them once.. are the "better" product of what they once were. But still there are also many animals exist who lived at that time or came right after it, they hardly changed during the ages. Which is fascinating for sure.

You are absolutely right about the squid and the crocodile but as far as a dinosaur, it would have to be a miniature version living in South America somewhere. A dinosaur would be just too large not to pick it up on satellite. Our military is pretty good with those things ha ha. As far as discovering new creatures go, if there is a dinosaur living in the Amazon rain forest or somewhere, I hope they never find it. They will only kill it or put it in a zoo.

I believe that "ancestors of the dinosaurs still exist. Sort of like family but not quite the same. Such as some species of birds can be found to have similar body structures and characteristics as the prehistoric birds

Yes, I believe they still exist. Aren't turtles and sharks prehistoric? If only we could somehow journey to the center of the earth and discover a lost world, I bet that then we would discover dinosaurs.
