This stunning phytolith comes from Litachne pauciflora (a bamboo).

It’s part of the 3D phytolith collection by @stromberglab.bsky.social, used for fossil phytolith classification and shape evolution of grasses

(4/5) One of the coolest parts? We built an open-access repository with 964 phytolith images—a digital reference collection for researchers to use! 📸

(3/5) 💡 Key findings:
✅ Some phytolith morphotypes & features are taxonomically diagnostic
✅ Phytolith production varies, but phytolith assemblage composition are consistent
✅ Plant part & taxonomy influence phytolith presence with high production in leaves and certain plant families

(2/5) Why does this paper matter? 🤔
Until now, there was no systematic dicotyledon phytolith reference for NW Europe, making it hard to interpret phytolith records in archaeology & palaeoecology. We tackled this by analyzing phytoliths from 117 plant specimens! 🌿
