Around 30,000 years ago, a hunter-gatherer left behind what may be a "personal toolkit" in what is now the Czech Republic, a new study finds.

Researchers uncovered the extraordinary cluster of artifacts in 2021 during an excavation at the Paleolithic site of Milovice IV. The "kit" contains 29 stone blades and bladelets that were found clumped together. The nature of the find indicates that the tools were bundled when deposited, likely in a container or case made from a perishable material, according to the study, which was published Aug. 13 in the Journal of Paleolithic Archaeology.

The find provides a remarkable glimpse into the life of a hunter-gatherer from the Paleolithic, which spans roughly 3.3 million years ago to just over 10,000 years ago.

The artifacts likely highlight an episode in the life of one person — which is "very rare" for the Paleolithic, study first author Dominik Chlachula, a researcher at the Institute of Archaeology of the Czech Academy of Sciences, told Live Science in an email.

Moreover, the discovery may shed light on the behavior of prehistoric people during migrations or hunting trips, which did not tend to leave behind many traces in the landscape and are therefore practically invisible to archaeologists, he said.
