Bones from Stegosaurus and Apatosaurus are still exposed in the rocks today, and can be felt and touched.
Dinosaur footprints at Dinosaur Ridge in Morrison.
Sauropod dinosaurs lived and died along the rivers.
Sometimes their bones were fossilized in the river mud and sand.
During this time, Iguanodon dinosaurs migrated along the western edge of the inland sea.

One of several dinosaur footprint at Dinosaur Ridge.
Instead of a depression in the rock, this footprint is raised.
The dinosaur probably stepped into soft ground, which later filled with sand and mud that solidified.
The softer rock around the impression eroded away, leaving the bulge.
