On Wednesday, a team of archaeologists has claimed to have found a 1.4 million year old flint in Spain, which they say is one of the earliest signs confirming human presence at the site.

According to the statements coming from the researchers, the recently found flint blade is approx 1.4 million years old. It is approx three centimeter (1.2 inch) long. The discovery has been made in the caves of Atapuerca in Spain i. e. the so-called Elephant Chasm cave.

It is the same site where similar other discoveries have also been made earlier. In the year 2007, the researchers found a human finger and jawbone there which they claimed dated back 1.2 million years. The recent findings are of great value, said Mr. Eduald Carbonell, one of the directors of the dig during a presentation of the discovery.

The site is located near the northern city of Burgos. Experts have been excavating it since 1978. Moreover, it was also classed as a world heritage site by UNESCO in the year 2000.

Researchers say that the cave has one and a half million years old parts. Along with the above discoveries, remains of a large bear, an ancestor to the brown bear that exists today, have also been found here.
