For years, scientists thought dinosaurs were just giant reptiles. Some dinosaurs were huge. But many were about the size of modern-day birds or dogs. Were dinosaurs warm- or cold-blooded? Paleontologists are still not sure. But they now believe a few dinosaurs were intelligent. Some smaller ones - like the two-meter Troodon - had fairly large brains.Was T. rex a powerful predator?[B] While some scientists think Tyrannosaurus rex was a powerful predator, others think the opposite is true. For example, in the movies T. rex is often a fast-moving giant. In reality, though, this dinosaur could not run fast. It was too large to move very quickly, so it probably moved about as fast as an elephant. T. rex also had very small arms and probably wasn't a powerful hunter. It may have been a scavenger instead, eating dead animals.Could dinosaurs fly?[C] Some reptiles, known as pterosaurs, were able to fly. But - even though they looked like them - these were not dinosaurs. Pterosaurs such as Tupuxuara could probably fly up to 16,000 kilometers nonstop. Scientists believe pterosaurs were actually very heavy. So they probably could not take off from the ground like birds. Instead, they first had to drop or throw themselves from trees in order to fly - much like bats.Are all dinosaurs extinct?[D] Dinosaurs completely disappeared about 66 million years ago. Scientists think they died out because of a global climate change: The Earth's temperature became too cold for them to survive. Now you can only see dinosaurs in museums. However, scientists believe that modern-day birds are, in fact, dinosaurs' descendants. If this is true, then dinosaurs' relatives are still walking - and flying - among us!

For 50 years, paleontologists searched for an answer to this question. In 1965, paleontologists discovered a pair of giant arms in Omnogovi, an area in Mongolia's Gobi Desert. The length of each arm was 2.4 meters. The claws were over 25 centimeters long. Paleontologists called the animal Deinocheirus (meaning "terrible hand").[B] What did the body of this animal look like? Paleontologists had different opinions, but no one knew for sure. They examined the area many times, but found only a few other fossils of the dinosaur. So scientists used Deinocheirus's arms to estimate its body size. Recently, however, a team of paleontologists dug up many more bones that tell us a lot about Deinocheirus's appearance.[C] Deinocheirus was one of the ornithomimosaurs - a type of dinosaur that looked like a modern-day ostrich. It was 11 meters long and weighed 6,000 kilograms - almost as big as a T. rex! Deinocheirus was clearly very big, but it was not a predator. It couldn't move quickly, and, in fact, it had no teeth. Its head looked similar to a horse's head, and it had a long tail, perhaps with feathers at the end. Most surprisingly, though, Deinocheirus had a rounded hump or "sail" on its back. This dinosaur probably ate fish, small animals, and soft plants. Why did it need such long limbs? Paleontologists now believe that its long arms were used simply to dig for food or to pull down high branches.[D] So the mystery of the terrible hand, it seems, has been solved. It is amazing to see what Deinocheirus actually looked like and to find out more about this giant dinosaur. But Darla Zelenitsky from the University of Calgary says it's "also sad in a way." Even scientists like a bit of mystery, and "that mystery is now gone."QUESTION: How long is Deinocheirus's body?
