Parallel dinosaur trackways
Three trackways of dinosaur footprints. The middle one was made by a bipedal dinosaur, and those on both sides by quadrupedal dinosaurs (sauropods). The rocky substrate consists of sandstones formed on a beach or coast at low tide. The substrate was originally wet and firm, but deformable. The direction of movement of the dinosaurs was to the left.
Cal Orcko dino trackways
Site of dinosaur footprints of Cal Orcko, in Sucre, where more than twelve thousand prints have been found on numerous trackways in this wall of limestone and sandstone inclined at about 70 degrees, 1200 m long, and 80 m high. Researchers have found almost 300 ichno species on this exposure.
