Key Findings
- The study from Turin University analyzed fossil fruits of the sedge genus Carex using advanced microscopy techniques
- Researchers identified a fossil from the Miocene of Siberia as belonging to Carex sect. Cyperoideae, based on silica body impressions
- This finding suggests Carex sect. Cyperoideae has been present in the Old World since the Miocene, challenging previous DNA-based hypotheses of a North American origin
