BISMARCK, N.D. (AP) - North Dakota's medical examiner says two bone fragments found along the path of the Dakota Access pipeline were not from a human.
The discovery Thursday came several weeks after the Standing Rock Sioux Tribe says it has found several sites of "significant cultural and historic value'' in the area, where protesters and private security clashed in September over construction.
Dr. William Massello says in a memo obtained by The Associated Press that the bones were from a "horse, cow or deer.''
The bone fragments were found Thursday during a tour with government officials and people from Energy Transfer Partners, as well as tribal members.
Standing Rock Chairman Dave Archambault was on the tour and says the discovery, human fragments or not, shows the need for more study.
