Million-year-old human tooth found in Spain

Spanish researchers said they had unearthed a human tooth more than one million years old, which they estimated to be the oldest human fossil remain ever discovered in western Europe.



Million-year-old human tooth found in Spain

Jose Maria Bermudez de Castro, codirector of research at the Atapuerca site said the molar, discovered on Wednesday in the Atapuerca Sierra in the northern province of Burgos, could be as much as 1.2 million years old.

"The tooth represents the oldest human fossil remain of western Europe. Now we finally have the anatomical evidence of the hominids that fabricated tools more than one million years ago," the Atapuerca Foundation said in a statement.

"Since it is an isolated fossil remain, it is not possible at this point to confirm which Homo species this tooth belongs to," the foundation added, but said first analyses "allow us to suppose it is an ancestor of Homo antecessor (pioneer)".

Researchers found the molar in the Sima del Elefante section of the Sierra Atapuerca, which had previously yielded fossils from mammals including bison, deer and bear as well as birds and a mouse.

Bermudez de Castro, one of three paleontologists leading the expedition, said the fossil appeared to be "well worn" and from an individual aged between 2025.

"For the time being we have no idea what species but there is no doubt, from the (geological) level where the tooth was found, that it belonged to the oldest European found to date," he added.

Excavations in recent years in the sierra have uncovered human remains ranging from early humans through the Bronze Age to modern man.
