Dinosaur Footprints
Exact Location
The footprints are found near the town of San Juan Raya, within the Tehuacán-Cuicatlán Biosphere Reserve. This semi-desert area is rich in fossils and geological formations.
Types of Footprints Found
At least three types of dinosaur tracks have been identified: carnivorous theropods, long-necked herbivorous sauropods, and herbivorous ornithopods.
Geological Age
The sedimentary layers are 95–113 million years old (Early to Middle Cretaceous).
Geological Formation
Part of the San Juan Raya Formation, a sequence of marine and continental Cretaceous rocks.
State of Preservation
Many tracks are well-preserved, visible outdoors on sloping rock slabs.
Scientific Value
These tracks help us understand dinosaur movement, environment, and whether they traveled alone or in groups.
Access and Tourism
San Juan Raya has a community museum and trained local guides who lead visitors along the trackways.
