The Acámbaro figurines controversy

Record summary

Thousands of fired-clay figures associated with Acámbaro became controversial after Waldemar Julsrud’s collection was publicized, because some pieces appear to depict humans alongside dinosaurs. Researchers and creationist writers used them to challenge conventional prehistory, while archaeologists generally regarded the assemblage as modern manufacture or mixed provenance. Later testing, collection history and inconsistencies in excavation documentation weakened claims of great antiquity. The case matters as a comparison between archaeological authentication, museum collecting and sensational interpretation, though individual specimens and testing histories should be checked separately.
