A fossilized footprint discovered in Bolivia is now the world’s largest footprint of a meat-eating dinosaur ever discovered.
While trekking in Maragua Crater, a tour guide found the 115-centimeter dinosaur footprint. Scientists claim it to be from the abelisaurus family, which were tall dinosaurs that walked on two legs and had a massive jaw and short arms, like the more popular Tyrannosaurus rex or T. rex.
The footprint also reveals that larger dinosaurs survived on earth longer than presumed. Larger dinosaurs were once thought to have lived 100 million years ago. However, the discovery challenged that notion since the footprint dated back to only 70 million years ago.
Maragua Crater is only 65 kilometers from the city of Sucre [SOO-kre], where about 10,000 tracks from 15 different species of dinosaurs have already been discovered.
In Sucre, the limestone cliff called Cal Orcko is where most of the dinosaur footprints discovered in the city can be found. One of the longest tracks in the cliff was from a baby T. rex dubbed Johnny Walker.
Studies say that Cal Orcko used to be a shore of soft clay where dinosaurs thrived. The clay dried and the footprints hardened and were preserved for millions of years. Over time, the shore was buried until a local cement company accidentally unearthed it. Fortunately, the company left the layer with the footprints intact because it was unsuited for making cement.
The cliff is now a tourist attraction in the process of becoming a UNESCO heritage site, a place of great cultural importance. If approved, UNESCO will raise $8 million to conserve Cal Orcko. Studies claim that, if left unprotected, the footprints may be wiped out by the year 2020.
