1000 year-old seeds dug up at Prehistoric Indian Village archeodome - Daily Republic

Researchers working the archaeological site along Lake Mitchell have discovered troves of small, charred kernels of corn and sunflowers, each only a few millimeters wide, that remain intact more than 1,000 years after people lived in the area... Alan Outram, who is in his 12th year bringing students from the University of Exeter, in England, to partner with Augustana College students, said the team has found as much carbonized plant matter in the last two weeks than from the last 11 years. Augustana College Professor of Archeology Adrien Hannus, who serves as the project director at the site, said when the archeodome was being built and finished in 1999, they got an idea of where the best deposits would be. That hinted to Hannus... They would be capped with clay and ash, because insects such as beatles can't survive climbing through ash, according to researchers. Source: www.mitchellrepublic.com
