Expedition FAQ
How do archaeologists date ancient artifacts?
Primary methods include Radiocarbon (C14) dating for organic materials up to about 50,000 years old, Potassium-Argon dating for older volcanic rock, stratigraphy (analyzing the layers of earth where the object was found), and dendrochronology (tree-ring dating for timber).
What caused the Bronze Age Collapse?
Historians generally agree it was a "systems collapse" caused by a combination of factors including severe prolonged droughts, devastating earthquakes, disruptions in international tin trade routes, and invasions by the mysterious "Sea Peoples."
Are there still lost cities waiting to be found?
Yes. With the advent of LiDAR (Light Detection and Ranging) technology mounted on drones or planes, archaeologists are continually finding massive, previously unknown urban complexes hidden beneath dense jungle canopies in Central America and the Amazon.
How were the Egyptian Pyramids built?
While theories vary, consensus suggests they were built by a massive workforce of skilled laborers (not slaves) using a system of ramps, sledges, and wet sand to reduce friction when moving massive limestone blocks quarried nearby.
What is the oldest known civilization?
Sumer, located in the historical region of southern Mesopotamia (modern-day Iraq), is widely considered the oldest known civilization, emerging around 4500-4000 BC.
Why did the Maya civilization collapse?
The "Classic Maya Collapse" (c. 900 AD) is attributed to a mix of overpopulation, systemic environmental degradation (deforestation), endemic warfare among city-states, and severe, multi-decade droughts.
What is the Rosetta Stone and why is it important?
It is a granodiorite stele inscribed with three versions of a decree issued in 196 BC (Ancient Egyptian hieroglyphs, Demotic script, and Ancient Greek). It provided the crucial key for modern scholars to decipher Egyptian hieroglyphs.
Do archaeologists get to keep what they find?
No. Professional archaeologists adhere to strict ethical and legal guidelines. Artifacts belong to the host country or state and are typically conserved and housed in national museums or research institutions, not kept for personal ownership.
