The Arica Monster was first spotted at the Atacama desert in Chile 1980. Witnesses describe a run in with huge kangaroo-like, bipedal monster in the deserts . The sightings have occurred by people who were traveling by car on different days through the remote road that links the cities of Iquique and Arica through the Atacama desert, some 2,000 kilometers north of Santiago, Chile. The newspapers in those cities collected recent accounts from citizens who claim to have seen the rare creatures. In addition, a military officer named Hernan Cuevas says that he spotted two of the beasts while traveling with two other adults and two children in a vehicle. He was quoted as seeing, "a huge beast, much like a two-legged dinosaur, with huge thighs."
They described the animal as being exactly like the raptor from Jurassic Park. In this case, it's said to be a living Dromaeosauridae.
Sapo De Loma is a mysterious large toad, living in river valleys of Andes Mountains of Chile and Peru. Eats medium-sized birds and rodents.
Toxodons are also represented in other art at the same site.
Below is the original notice, in Spanish. I am not assigning any identity to the remaining examples at this time, these were the ones I had something relevant to say about.
