Baby tooth places macaques in northern Germany over 300,000 years ago

A research team comprising scientists from the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen and Leiden University in the Netherlands has closely examined a single fossilized tooth. Discovered at the renowned Schöningen archaeological site in Lower Saxony, this small specimen has yielded significant insights into the prehistoric environment of northern Europe.

The study, recently published in the scientific journal Quaternary Environments and Humans, centers on a baby tooth belonging to a macaque. The presence of these primates so far north during this specific chronological timeframe offers a fascinating window into past ecological conditions, challenging previous assumptions about the northern limits of primate habitats during prehistoric warmth phases.

Schöningen is globally famous for its exceptionally well-preserved Lower Paleolithic sites, most notably yielding the world's oldest completely preserved wooden hunting weapons. The addition of primate remains to this already rich archaeological assemblage adds another layer of complexity to our understanding of the local ecosystem inhabited by early humans and the diverse fauna surrounding them.

During the Pleistocene epoch, animal and plant distributions shifted dramatically in response to glacial and interglacial cycles. The identification of macaque remains indicates that periods of interglacial warmth allowed certain temperature-sensitive species to expand their ranges significantly further north than they can today under current natural European conditions.

Analyzing micro-features of teeth remains a powerful tool in modern paleontology. Dental morphology and wear patterns allow researchers to accurately identify species even from fragmentary remains, providing clues about diet, developmental stages, and environmental stressors experienced by the animals during their lifetimes.

Ultimately, this discovery underscores the dynamic nature of European ecosystems hundreds of thousands of years ago. By continuing to study sites like Schöningen, scientists can piece together how climate fluctuations shaped the distribution of both fauna and hominin populations throughout deep time.
