Almost 400 years after the Pilgrims celebrated their first Thanksgiving, archaeologists have unearthed evidence of the original 1620 settlement in Plymouth, Mass.

Researchers from UMass Boston s Andrew Fiske Memorial Center for Archaeological Research made the find on Burial Hill in Plymouth.

Burial Hill includes a cemetery that was thought to be part of the original settlement, according to the Boston Globe, although the site had never been dug by archaeologists before.

A team led by Fiske Center Associate Director David Landon were thrilled to discover 17th-century artifacts such as pottery, tins, trade beads and musket balls.

The artifacts were discovered around so-called post and ground construction – holes for wood where structures once stood.

Soon, they discovered the remains of a calf buried in a pit.
