Understanding Archaeological & Genetic Terminology

Period Abbreviation Glossary

Comprehensive guide to period abbreviations used in ancient DNA sample names across 40,000+ years of human history.

Why This Glossary Matters

Ancient DNA sample names often contain cryptic abbreviations like "LN", "EBA", or "IUP" that represent specific archaeological periods and cultures. MYDNATLAS automatically expands these abbreviations into human-readable names, but understanding the original terminology helps you better interpret your genetic ancestry results.

This glossary covers 29,688 ancient samples spanning from the Upper Paleolithic (~45,000 years ago. The oldest surviving human DNA) to the Early Modern period (1900 AD), organized by major archaeological periods and genetic ancestry components.
