Guide Discovers Record-Setting Dinosaur Footprint (Photos)

A Bolivian tour guide has discovered the largest meat-eating dinosaur footprint ever.

The nearly 4-foot-wide dinosaur footprint is believed to have been made by the Abelisaurus, a biped dinosaur that once lived in South America, according to Argentine Paleontologist Sebastian Apesteguia, who is studying the footprint, The Guardian reports.

The dinosaur footprint was found in Bolivia by local tour guide Grover Marquina on July 19 about 40 miles outside the city of Sucre, a place well known for dinosaur tracks given its soft clay surface.

Skeletal remains of the Abelisaurus have previously been found around Sucre.

“This print is bigger than any other we have found to date in the area,” Apesteguia said. “It is a record in size for carnivorous dinosaurs from the end of the Cretaceous period in South America.”

Prior to Marquina's discovery, the largest track from a meat-eating dinosaur had been found in New Mexico, CNN reports.

The Abelisaurus is similar in nature to Tyrannosaurus Tex, having a 40-foot stature and walking on two legs with stunted arms.

The footprint has set a new record, while also challenging a former belief about dinosaurs that lived during the Cretaceous period, the last age of dinosaurs.

Apesteguia told CNN that the discovery of the footprint means gigantic dinosaurs did live through the latter part of the Cretaceous period, an idea that has been ignored up until now.

The so-called gigantic dinosaurs were believed to have lived in South America 100 million years ago, not 70 million years ago as the footprint suggests.
