We see them everywhere, not only in museums, but also in movies, magazines, and even in the toys we get from McDonald's. Since the days of early cinema, dinosaurs have captured our imaginations. They are often shown as scaly beasts with sharp horns and crocodile-like bellies . But the big screen dinosaurs are "a leap from what we know", Mark Norell, who studies dinosaurs at the American Museum of Natural History in New York, told Discover magazine. The reality of drawing dinosaurs for movie studios, magazines, or museums is that the artist often only has half of a skeleton to work with. Many existing and newly-discovered dinosaurs do not have a complete skeleton, which makes it difficult to tell what they looked like. And even with a complete skeleton, there is a lot of room for interpretation. "Look at an elephant's trunk and ears," Jason Brougham, a dinosaur sculptor at the American Museum of Natural History, told Discover magazine. "It's impossible to guess those features by only looking at the skeleton." Researchers suggest that the dinosaurs of old could have had trunks like an elephant or even red necks like a turkey. They could have had colorful spots, stripes , and other interesting patterns on their bodies, just like snakes. Yet, with only a few fossilized bones to study, it is impossible to know for sure. Remember the cruel and quick-running velociraptors in the US film Jurassic Park? Now experts believe that they were much smaller than in the movies, about the size of a large chicken, the BBC has reported. Since the 1990s, some well-preserved dinosaur fossils have been found in China's Liaoning province. Thanks to that, we have known for a while that one group of dinosaurs was covered in feathers. And thanks to the recent discovery of a feathered plant-eating species in Russia, many scientists now believe more dinosaurs than we previously thought had feathers, much like a chicken. Also, in 2007, scientists confirmed that... Question: Jason Brougham used the elephant as an example to show that _ .

No one is ever too old to enjoy them or too young either. In fact, many of the most successful tricks are really quite simple. They don't require special equipments or hours of practice.

Put the cards facedown on a table, and ask your friend to pick a card. Then place the card at the bottom.

Also, the fish that Asians consume have very strong immunological effects, providing more antioxidants than the red meat preferred in America. The average American family has more than one car.
