"Every archaeological site contains a wealth of information about the past, and context is key. A knife found by a stone hearth tells a different story than one alongside a human skeleton. Unfortunately, excavating the site to reveal the story also destroys it. Detailed records are the only way archaeologists can keep archaeology from erasing the past rather than preserving it. Today, they're using 3D modeling tech to preserve the information found in a site, find new places to dig, or create models of ancient artifacts via 3D printing."
