A fossilized tooth recovered from the Galería site in the Sierra de Atapuerca (Burgos, Spain) confirms that reindeer (Rangifer) inhabited this area of the Iberian Peninsula between 243,000 and 300,000 years ago. It represents one of the southernmost reindeer remains ever found in Eurasia and constitutes the earliest record of glacial fauna in the Iberian Peninsula, according to a study published today in the journal Quaternary.
