- A Dinosaur Freeway, serving as a primary thoroughfare for dino travel, existed 98 million years ago in Colorado.
- Dinosaurs that traveled on the freeway included large plant eaters, armored species, and dinosaurs that looked like ostriches.
- Tracks made by crocodiles and pterosaurs were also found at the site, which was once a coastal plain.
Colorado's bustling thoroughfare 98 million years ago was the Dinosaur Freeway.
Over 350 newly discovered tracks, made by various dinosaurs, crocodiles and a few pterosaurs, were identified at the site, which is now the John Martin Reservoir in Bent County, Colorado. When added to previously found tracks there, the total number of fossilized prints is well over 1,000. The dinosaur freeway is described in the February issue of Cretaceous Research.
"The Dinosaur Freeway runs from Northeast Colorado, near Boulder, to east central New Mexico, near Tucumcari," co-author Martin Lockley told Discovery News. "It is a trampled zone in Cretaceous rocks representing an ancient coastal plain like the present day Gulf of Mexico."
