The back carvings on some Moai statues were NOT original! New research shows they were added centuries later by specialists. The carvings depict ceremonial designs which some researchers associate with the later Birdman cult. Microscopic analysis reveals these were added over hundreds of years in layers. The motifs show bird figures carved in low relief or incised. A British Museum basalt Moai shows birdmen figures with bird characteristics. However, the exact origin date of the Birdman cult remains uncertain - sources conflict on timing.
