LISBON, July 5 — Archaeologists have discovered several prehistoric rock engravings estimated to be more than 23,000 years old at Portugal’s Coa Valley Archaeological Park, according to the reports of Lusa news agency on Sunday.

The findings were made on the so-called “Rock 9” of the Fariseu archaeological site, where excavation work began in 2020 and where the world’s largest known aurochs engraving — a 3.5-meter depiction of a wild bull on a schist — was found on the same year, said the reports quoting researchers.
