Description
Dinosaurs and their remains have fascinated mankind for thousands of years. These incredible creatures first roamed the earth around 220 million years ago for 155 million years before they mysteriously disappeared. The fossils and other remains that became their legacy have led to some understanding of these often ferocious beasts. It is possible to tell the species, size, behavior, appearance, and family structures of dinosaurs. Detailed examination of fossils gives valuable insight into how they lived for millions of years before humans found their place on the planet around 100,000 years ago.
It is estimated that more than 1,500 different species of dinosaur existed, but currently, there is no concrete evidence to back this up. While all these species are believed to be extinct, if scientific studies are correct, it is possible that “living dinosaurs,” particularly within species of birds, still exist today.
There are a large number of theories about why dinosaurs disappeared 65 million years ago. Some experts cite changes in environments, over many millions of years, and disease, which brought about their demise, while others believe that a major catastrophe, possibly involving meteorites, was to blame. Whatever the true cause of the extinction of dinosaurs, it remains unknown and unproven. Whether plant eaters or meat eaters, what we do know about these exciting species is that they continue to cause speculation and doubt, as well as new theories, well into the 21st century.
