πŸ—£οΈ New paper! πŸ—£οΈ

The mobility patterns of the population of Gallo-Roman Tienen (Belgium) are keeping you up at night? Wondering if there is more than mobility reflected in these 87Sr/86Sr results? This is very relatable, and conveniently, I have the right paper for you! It's accessible right there πŸ‘‡

πŸŽ‰ Thrilled to share our new paper just published in @PLOSONE!

In this study we explored how weather & seasonality impact cremation conditions using experimental archaeology, FTIR-ATR, and isotope analysis.

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

Next time you feel the sharp sting of a nettle (Urtica), think of its fascinating stinging microhairs - here around 150–200 Β΅m in length - with irritating chemicals stored in their bulbous heads. 
The study study investigates plant silica bodies (phytoliths), including these microhairs and other morphotypes, of extant dicotyledons prevalent in North-Western Europe, establishing a baseline for botanical, archaeobotanical, and palaeoecological research.

(2/5) Why does this paper matter? πŸ€”
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! 🌿
