Since ancient times, people have used bones and fossils to imagine what animals that lived in the past were like. When scientists and paleontologists study dinosaur bones, it’s not easy for them to identify what dinosaur the bones belong to. Therefore, computers and other technology have been a big help to paleontologists in identifying bones, parts of dinosaurs and to whom they belong to. (Houghton Mifflin Harcourt StoryTown, 2008)
