Dinosaur remains are the preserved bones, teeth, and other parts of dinosaurs that lived millions of years ago. These fossils provide important information about the size, shape, and behavior of different dinosaur species. Paleontologists study these remains to learn how dinosaurs lived and evolved over time. Fossils can be found in sedimentary rock layers, often in areas that were once rivers or lakes. The process of fossilization occurs when organic material is buried and mineralized over time. Notable dinosaur remains, such as those of Tyrannosaurus rex and Triceratops, have been discovered in various locations around the world, helping scientists piece together the history of these ancient creatures.
