The Dinosaur Record
Follow the fossil evidence to see how dinosaurs looked, moved, evolved, and lived—and where the science still leaves room for debate.
The Dinosaur Record begins with the evidence that survived: bones, teeth, eggs, footprints, feathers, and the rocks around them. Those clues can reveal how an animal grew, moved, fed, and shared its environment—but they do not answer every question equally well.
Each explanation separates direct fossil evidence from scientific inference and open questions. The aim is not to make dinosaurs look more dramatic than they were. It is to show how paleontologists reconstruct animals and ecosystems that no human ever saw.
