The U.S. Customs and Border Protection announced Wednesday officers seized a package of five jars of containing the artifacts found May 25 on a Canadian mail truck. The truck had been selected for examination at a nearby station in Marysville, Michigan.
Officials say they worked with a Washington-based archaeological organization and determined the artifacts are believed to be from the Ptolemaic Dynasty from 305-30 B.C. Their removal from Egypt appears to be a violation of federal law.
Authorities say they plan to return the artifacts in the near future and are working to determine who is criminally responsible.
