Summary Author: Len Sharp
Shown above is Dinosaur Ridge, located just a few miles from downtown Denver, Colorado. Dinosaur Ridge is a feature known as a hogback. It consists of highly-eroded, Dakota strata. The footprints are dinosaur tracks running steeply up the slope of the hogback. They're found in Dakota Sandstone rocks of the late Cretaceous Period and possibly belong to an Ornithomimus and an Iguanodon. Skeletal remains of dinosaurs including Stegosauruses and Allosauruses have been quarried from near here for over a hundred years. Photo taken in July 2011.
