Summary[edit]
DescriptionMagnoavipes (theropod dinosaur track) (Dakota Sandstone, Lower Cretaceous; Dinosaur Ridge, Colorado, USA) 4.jpg |
English: Magnoavipes sp. - dinosaur track in the Cretaceous of Colorado, USA.
Dinosaur Ridge, Colorado has numerous dinosaur fossils, including bones and tracks. The most common track type at the site is Caririchnium leonardii, which was made by an iguanodontid dinosaur. A less common track is this - a slender, three-toed print called Magnoavipes, which was made by a theropod dinosaur - apparently Ornithomimus. The dark gray coloration of the track is not natural - charcoal has been used to highlight the dinosaur footprints at this site.
