British scientists have created what they believe is the best three-dimensional model of a dinosaur ever built.
They say the model is almost the exact the length, width and height of a real dinosaur called a Psittacosaurus.
The Psittacosaurus was a plant-eating creature about the size of a large dog.
The model has colors and markings that scientists think the creature had when it lived in what is now northern China about 100 million years ago.
Hundreds of dinosaur fossils have been discovered in the area -- including complete remains of some creatures.
The British scientists created their model with help from a fossilized remain that had preserved skin pigment.
Jakob Vinther is with the University of Bristol.
"Getting exceptional preservation and being able to tell colors in a fossil is really unique. Usually you only get the hard parts preserved, such as bone or shell. But under exceptional circumstances we can be lucky and find soft tissues and also these pigments preserved."
The scientists believe the colored markings show that the Psittacosaurus lived in forests with plenty of trees and other plant life. They also believe the dinosaur's markings made it difficult to be seen by other animals who wanted to kill it.
