More than 50 cave etchings thought to be around 14,500 years old have been found in the northern Spanish town of Lekeitio.

Bizkaia regional official Unai Rementeria announced the discovery in a press conference Thursday, saying the etchings were a “treasure of mankind,” and “of exceptional technical quality and visibility.” He said experts have praised the etchings as the “most spectacular” in the Iberian peninsula. 404 more words
