Acambaro Figures

The Acámbaro Figures are small, ceramic figurines found in July 1944 in Acámbaro, Guanajuato, Mexico by Waldemar Julsrud.

The figurines are said by some to resemble dinosaurs and are sometimes cited as anachronisms or as Out-of-place artifacts. Some young-earth creationists have adduced the existence of figurines as credible evidence for the coexistence of dinosaurs and humans, something that would cast doubt on scientific dating methods and potentially offer support for a literal interpretation of the Bible...

Archaeologist Charles C. Di Peso was working for the Amerind Foundation, an anthropological organization dedicated to preserving Native American culture. Di Peso examined the figures and determined that they were not authentic, and had instead been produced by local modern day farmers, publishing his results in the journal American Antiquity. Supporters of the figures have subsequently attempted to cast doubt on the accuracy of his investigation...

Supporters cite many individuals' firsthand accounts of the excavation and the matrix from which the artifacts were discovered. According to Swift, the area surrounding the figures was clearly an ancient strata and if the figures had been planted as a hoax, there would be evidence of disrupted strata.

The Acambaro figurines are an example of fringe evidence that can do the creationist cause more harm than good when put forth as hard evidence. While they may be authentic, the weight of the evidence seems to be against that. Even if they are authentic, they may not be what they appear to be.
