Stormy and the Allosaurus Tracks

Copper Ridge Sauropod
Dinosaur Trackway
Moab, Utah

        The Copper Ridge Sauropod Track site contains fossil tracks of a turning brontosaur and four carnivores of various sizes.  The trackway was discovered in 1989.  The tracks are from the Jurassic period.

          The brontosaur tracks show a pronounced turn to the right.  This change of direction is very unusual in fossil trackways.  It is unknown which species of brontosaur made these tracks.  The most likely candidates are Camarasaurus, Apatosaurus or Diplodocus.

          The three-toed tracks range in length from eight to fifteen inches.  The large tracks probably belong to an Allosaurus, which was the most common carnivore during the period in which this trackway was formed.  It is interesting to note that the trackway to the southeast shows an alternation of long steps (approximately 5 feet) and short steps (approximately 4 feet).  This irregular stride has never been explained.  It has been suggested that the dinosaur was hurt and limping slightly.  The smaller three-toed tracks, which are hard to see, could have been made by a number of smaller bipedal species.

          Fossil footprints are a rare, non-renewable resource.  This trackway is rare for its abundance of varying tracks.  Please help preserve and protect them.
