They've been extinct (灭绝) for more than 65 million years. They left no pictures but libraries were filled with books about them. Yet, they live on in the imaginations of people. Mention the word "dinosaur" to anyone and you're sure to have something to talk about.
We have known about these strange living things for more than 200 years. Their fossil (化石) record was first discovered in 1818. The word "dinosaur" was created in 1842 by a scientist who put two Greek words together.
What we know about dinosaurs comes only through the fossil record they left behind. We can get an idea of how they looked by building their skeletons (骨架) with fossilized bones and teeth. They must have been amazing as they towered high above the other living things of their time. We do know that they lived on land and walked. Some walked on two legs. Others preferred four legs. Some were fast and others were quite slow.
We have a pretty good picture of their size and structure, but not much else is known for certain. For example, what color were they? Nobody knows. Did they cry like lions, or were their voices sweet and musical like birds? Again, how can we know? The fossil record does not speak.
Keep in mind that what we don't know about dinosaurs is far greater than what we do know about them. As with a lot of researches about that era, scientists often have to read between the lines.
