Human remains from Clovis Time Period Found At Montana Burial Site.

Anzick burial site was first discovered in 1968 by a team of construction workers who were working in this remote region, during the digging process the construction team found human remains along with some stone spears and antler tools that seemed to be from Clovis time period. This is the only site where Clovis period artifacts and human remain have ever been found by now.

However, founded remains of the child and other artifacts raised a lot of questions in regard to the timeline of these early settlers of North America. So, a team of researchers decided to properly date the newly found evidence by using special dating techniques.

Initially, traditional dating methods showed a variation between the human remains and the other found artifacts.

“One thing that has always been a problem has been the accurate dating of the human remains from the site,” explains Waters.

“The human remains yielded a younger age that was not in agreement with the ages from the antler artifacts which dated older than the human remains. If the human remains and Clovis artifacts were contemporaneous, they should be the same age.”

The research team including Michael Waters, director of the Center for the Study of the First Americans and his colleagues from the Oxford University and Stafford Research of Colorado recently published their findings in the latest issue of Proceedings of the National Academy of Sciences.

To properly date the human remains to an exact timeline they used the process of Amino Acid Radiocarbon Dating, a specific amino acid called hydroxyproline was isolated from the bones of the child remains and instead of carbon, the extracted hydroxyproline was used for dating them to an exact time period.

“This amino acid could only have come from the human skeleton and could not be contaminated,” Waters adds.

“The other previous ages suffered from some sort of contamination. With the new method, we got very accurate and secure ages for the human remains based on dating hydroxyproline. As a test, we also re-dated the antler artifacts using this technique.”

The new dating process proved that the artifacts and the human remain belonged to the same time period.

“The human remains and Clovis artifacts can now be confidently shown to be the same age and date between 12,725 to 12,900 years ago,” Waters notes. “This is right in the middle to the end of the Clovis time period which ranges from 13,000 to 12,700 years ago.
