BBC News - Cave paintings in Mexico: Carvings uncovered in Burgos:
"The paintings were found in 11 different sites - but the walls of one cave were covered with 1,550 scenes.
The area in which they were found was previously thought not to have been inhabited by ancient cultures.
The paintings suggest that at least three groups of hunter-gatherers dwelled in the San Carlos mountain range.
Experts have not yet been able to date the paintings, but hope to chemically analyse their paint to find out their approximate age."
