What is the conventional archaeological date of Nazca Lines (Peru), and what alternative dates have been proposed?

Conventional date: Ground drawings made by removing surface stones on the desert of southern Peru. UNESCO dates the tradition from about the 8th century BC to the 8th century AD. Alternative proposals: Interpretation: Sakai and colleagues (2024): Who used them, and how? The authors think the small figures were made and seen by single people or small groups walking the trails. They think the giant figures were made and used by whole groups for ritual. That is their reading of where the figures sit.

What has been measured at Nazca Lines (Peru) in peer-reviewed studies?

AI found 303 new figures: A 2024 study ran an AI system over the whole Nazca area. With six months of field checks, it found 303 new figure drawings. Before that, about 430 were known after nearly a century of searching. Small figures near trails: The small 'relief-type' figures mostly show people or things people changed, such as tame animals and cut-off heads (81.6%). They lie on average 43 m from old foot trails. Giant figures near the lines: The giant 'line-type' figures mostly show wild animals (64%). They lie on average 34 m from the network of long lines and trapezoids. A date from near Palpa: Rink and Bartoll (2005) give a luminescence date of AD 400–650 for geometric lines on mesas near Palpa, not the Nazca plain. A huge area: UNESCO says the protected area covers about 75,358 hectares of desert plain. The Nazca Lines are huge drawings on the desert floor of southern Peru. People made them by clearing away dark surface stones to show the lighter ground below. They include straight lines, trapezoids and figures of animals and people. A 2024 study used AI to find many new small figures and compared where the two kinds of figures sit.
