THE EXPEDITION OF A TEAM OF 15 PEOPLE LASTED 22 DAYS

They find traces of sauropods and a pre-Hispanic bridge used by cultures of Chuquisaca.

HALLAZGOS. Las posibles huellas de dinosaurio y el puente prehispánico.

An expedition lasting 22 days carried out by North American explorers and a Bolivian guide along the Grande River concluded successfully with indications of two findings: one paleontological and the other archaeological. CORREO DEL SUR learned about the story of this journey that crossed four departments of Bolivia.

The expedition began in the municipality of Colquechaca, Potosí, on January 14th. The team of 15 people, consisting of firefighters, paramedics, fishing entrepreneurs, and rafting guides from the United States and Canada, departed from the Chayanta River to the Poroma River in Chuquisaca, then to the Mizque River in Cochabamba, and finally concluded in the Amazon of Santa Cruz.

During the journey, which ended on February 4th in the town of Abapó, municipality of Cabezas, Santa Cruz, the group completed one of the longest rafting trips known in Bolivia.

“We have descended, over the 22 days, along the 636-kilometer river (…), we have seen endemic species such as the red macaw and the Andean condor, which accompanied us in the different canyons and in the Amazon, as well as toucans and capybaras,” recounted César Saavedra, the only Bolivian guide part of the exploration team from the American company Sierra Ríos.

Discoveries

In Cochabamba, specifically in the community of Yuthuni Grande, near Aiquile, the explorers found the ruins of a pre-Hispanic bridge, previously spotted by Saavedra, which was possibly used by the Mojocoya and Yampara cultures of Chuquisaca to move to Omereque in Cochabamba.

This archaeological vestige would demonstrate more precisely the relationships of the pre-Hispanic cultures that inhabited that region.

Further downstream, “we have also been able to appreciate further evidence of what is very likely to be dinosaur footprints,” Saavedra reported, specifying that this discovery occurred in the Pasorapa sector, Cochabamba, where there are traces of possible footprints.

Swiss paleontologist Christian Meyer, who studied the footprints of Cal Orck’o and will return to Bolivia in September to analyze the footprints of Toro Toro, told this newspaper that they could be footprints of sauropods (long-necked dinosaurs), although further studies are needed.

Saavedra, who promotes rafting trips with his company “Mi Río,” stated that rafting trips are safe, as long as they are led by experts who know the route and companies that offer guarantees.

POLLUTION

During the expedition, pollution of the Grande River with plastic (bottles and bags) generated in different cities was observed, so it is urged to stop using this material and use other more solid materials that can be reused.
