If you’ve ever wondered what lies at the bottom of a river, you’ve got your answer. Archeologists recently drained a canal in Amsterdam, and catalogued everything they found. The findings date all the way back to over 100,000 B.C., and present a comprehensive picture of what objects have been important to Dutch society throughout history.
You can start browsing the catalog from either the top (2005) or the bottom (-119000), but the oldest artifacts found in the river were shells thought to be over 100,000 years old. As for human remnants, there are old rock-carved blades and utensils belonging to prehistoric man, dating back to 5,300 B.C., and even the ancient bones of large mammals like bears, sheep, and goats.
