STARTING THE QUARRY

This was the beginning—the beginning of the celebrated dinosaur quarry which was to yield such a multitude and variety of ancient forms to science, and eventually lead to the establishment of Dinosaur National Monument.

Douglass proceeded to dig into the solid rock along those original eight tail bones and found other parts of the skeleton. In time, the almost complete frame of the Apatosaurus was exposed. The skull was missing and parts of the limb bones, but this was to be expected, as fossil vertebrates are rarely preserved in their entirety. What was not expected were the remains of a smaller dinosaur comingled with those of its huge contemporary.
