Dinosaur research involves the study of fossils, which are the preserved remains of dinosaurs and other ancient life forms. Scientists, known as paleontologists, excavate these fossils from rock layers to learn about the physical characteristics, behavior, and habitats of dinosaurs. This research helps us understand how dinosaurs lived and evolved over millions of years. In addition to fossils, dinosaur research also includes the study of geological formations and ancient ecosystems. Techniques such as radiometric dating allow researchers to determine the age of fossils, while CT scanning provides detailed images of fossilized bones. Together, these methods contribute to a clearer picture of the prehistoric world.
