"Landon’s team did however find various 17th century artifacts around the post and ground construction, including pottery, trade beads, tins and musket balls. Landon says that at the point of discovering the artifacts, his students and researchers became cautiously optimistic that they had found a location inside the settlement walls. The next find was “Constance” – a calf buried in the bottom-most pit. As native people didn’t have domestic cattle, Landon and his team know that Constance lived and died in the confines of the original Plymouth settlement." http://sciencenewsjournal.com/original-1620-plymouth-settlement-discovered/
Important discovery. I hope they develop it like the Virginians did Jamestown. That site is a wonderful visit.
