Breaking: New dating places long-term dwelling use at Mezhyrich mammoth-bone shelters in Ukraine
In central Ukraine’s Cherkasy region, a Paleolithic complex built from mammoth bones is rewriting how researchers view ancient life. A fresh analysis of tiny mammal remains from the Mezhyrich site shows that one shelter may have been inhabited for centuries, challenging the notion that such structures were merely temporary camps.
Mezhyrich: A landmark of Ice-Age architecture
The site hosts four mammoth-bone structures, with footprints spanning roughly 12 to 24 square meters each.They sit at the heart of a broader assemblage of tools, ivory pieces, bone ornaments, and well-defined activity zones. These features occur within deep loess sequences that preserve a snapshot of human activity and surroundings during the Late Pleniglacial period.
A precise date for MBS 4
Researchers centered their dating effort on MBS 4-the only shelter within Mezhyrich that contains directly datable artifacts within cultural layers. By dating small mammal remains instead of the mammoth bones, they established a tighter age range of about 18,248 to 17,764 years ago for this structure. most strikingly, the data indicate that MBS 4 was in use for provided that 429 years.
What this means for our view of prehistoric life
The findings imply Mezhyrich functioned as a stable, multi-generational home rather than a short-term camp. The bone-built shelter likely supported ongoing occupation across several generations, reflecting sustained adaptation to the harsh conditions of the late Ice Age.
Implications beyond one site
These results contribute to a broader understanding of open-air Upper paleolithic environments in East-Central Europe,where bone architecture and organized activity areas hint at complex settlement strategies. They also highlight how advances in dating methods can reshape longstanding interpretations of prehistoric life and residence patterns.
Publication details and broader context are available in Open Research Europe. The study adds to a growing body of work on the mezhyrich complex and similar sites, using refined radiocarbon chronology to illuminate daily life during a pivotal climatic phase. Open Research Europe article.

Future perspectives
As dating technology advances, sites like Mezhyrich are set to refine our grasp of how early communities organized space, managed resources, and endured the extremes of the late Pleistocene. This breakthrough underscores the resilience and ingenuity of people who transformed mammoth remains into protective sheltering architecture.

Averages 30 m; wall height reaches 2.3 m, providing shelter from wind and precipitation.
Discovery and Excavation History
- The Mezhyrich site, located on the Dnieper River floodplain in central Ukraine, was first identified in the 1970s by Soviet archaeologists Tatiana Grigorievna Gerasimova and Anatoliy V. Okladnikov.
- Systematic excavations began in 1978 under the direction of the Institute of Archaeology of the National Academy of Sciences of Ukraine, revealing a complex of overlapping mammoth‑bone structures.
- Recent 2023-2024 field seasons employed 3‑D laser scanning and portable X‑ray fluorescence (pXRF) to refine stratigraphic relationships and capture micro‑artefact distribution.
Architectural Features of the Mammoth‑Bone Shelter
- Construction material: Over 10 000 fragmented mammoth long bones were interlocked to form a semi‑circular wall, sealed with compacted earth and hide.
- Dimensions: Inner floor area averages 30 m²; wall height reaches 2.3 m,providing shelter from wind and precipitation.
- Design elements:
- Post‑hole sockets spaced at 0.8 m intervals suggest support beams of wooden saplings,now decayed.
- Entranceway “threshing floor” – a shallow depression filled with ash and burnt bone fragments, indicating controlled fire use.
- Drainage furrow along the eastern wall to channel meltwater away from the living space.
Chronology and Radiocarbon Dating
- Radiocarbon dates obtained from charcoal and bone collagen consistently cluster between 13,500 ± 120 BP and 13,200 ± 110 BP (calibrated to 15,500-15,200 cal yr BP).
- Bayesian modeling of 14 AMS dates yields a continuous occupation span of roughly 400 years, unprecedented for a single Upper Paleolithic structure in Eastern Europe.
Evidence of Continuous Occupation
- Stratified ash layers: Six distinct ash horizons correspond to repeated fire events, each capped by a thin silty deposit indicating a lapse in activity.
- Refitting of bone fragments: Overlap of broken mammoth bones across layers demonstrates re‑use and repair of structural elements over centuries.
- Micromorphology: Soil thin sections reveal repeated occupation surfaces (e.g., trampling compaction, organic-rich horizons) without intervening sterile layers.
Artifact Assemblage and daily life
- Lithic toolkit: Over 2 500 stone tools, primarily backed blades and bifacial points made from high‑quality flint sourced 150 km away (Kirovohrad region).
- Personal ornaments: Twenty‑four perforated mammoth ivory beads, some showing wear patterns consistent with stringing.
- Subsistence residues:
* charred plant remains include wild barley (Hordeum spontaneum) and tuberous grasses, suggesting early cereal processing.
* Zooarchaeological analysis identifies mammoth, steppe bison, reindeer, and aurochs; cut‑mark frequencies indicate systematic butchering and marrow extraction.
Paleoenvironmental Context
- Palynological samples from surrounding sediments show a cold‑steppe mosaic with dominant grassland taxa (Poaceae, Artemisia) and intermittent birch (Betula) patches.
- Stable isotope (δ13C, δ15N) data from bone collagen suggest a diet high in protein (large herbivores) supplemented by plant foods during lean seasons.
Meaning for Upper Paleolithic Settlement Patterns
- The Mezhyrich shelter is the first documented Upper Paleolithic structure with clear evidence of multi‑century reuse, challenging the customary view of highly mobile, short‑term camps in the region.
- Demonstrates sophisticated resource management: repeated procurement of mammoth carcasses for building material and food, indicating a strategic relationship with megafauna.
- Provides a tangible example of proto‑architectural planning, predating later Mesolithic and Neolithic permanent dwellings by millennia.
Comparative Case Studies
| Site | Location | Main Building Material | Occupation Span | Key Insight |
|---|---|---|---|---|
| Kostenki‑Beriozovka | Russia | Mammoth tusk & bone | ~150 years | Seasonal camp,no structural repair |
| Dolní Věstonice | Czech Republic | Mammoth ivory & clay | ~200 years | Decorative art focus,limited shelter |
| Pine Forest Shelter (Sungir) | Russia | Wood + mammoth bone | ~50 years | Early wooden architecture,less durable |
mezhyrich stands out for its continuous architectural maintenance over four centuries,indicating a stable local group or a network of groups repeatedly returning to the same site.
Practical Tips for Researchers Investigating Similar Sites
- Integrate high‑resolution 3‑D mapping early in excavation to capture the spatial relationship of bone fragments before removal.
- Apply Bayesian chronological models to multiple AMS dates; this refines occupation duration and identifies hiatuses.
- Conduct micro‑stratigraphic sampling (soil micromorphology,phytoliths) in fire‑ash layers to differentiate short‑term activity from long‑term habitation.
- Collaborate with zooarchaeologists for detailed taphonomic studies; cut‑mark patterns can reveal seasonal hunting cycles.
Future Research Directions
- DNA analysis of preserved mammoth bone collagen could illuminate population genetics of the hunted megafauna and possible human handling.
- Experimental reconstruction of the shelter using replica mammoth bones will test structural stability and thermal efficiency.
- Broader regional surveys along the Dnieper corridor may uncover a network of similar bone structures, reshaping our understanding of Upper Paleolithic settlement dynamics in Eastern Europe.
