First noted by Matt Mossbrucker and later described by Dr. Martin Lockley,
this theropod (a carnivorous dinosaur) track was part of the top layer of sandstone at
the Bone Site, 50 yards to the north. During road construction in 1937, this boulder
was removed from the hillside and later moved to this location in 2013.
The sharp toe impressions show that this was a theropod. Since Allosaurus teeth
and bones were found here in 1877, this footprint may be from a young Allosaurus.
Other possibilities include Torvosaurus or Ceratosaurus.
From the footprint, one can determine the animal's size. Multiply the length of the
footprint (9 inches) by 5 to get the leg length (45 inches). For a Jurassic theropod,
multiply the leg length by 3 to get the theropod's head to tail length.
45 inches x 3 = 135 inches or 11.5 feet
The theropod that left this footprint would have been 11.5 feet long.
