A great and detailed #study about early #medieval #migration events to #England from 400–1100 AD. The study concludes that, contrary to the #traditional #narrative, there was no abrupt migration event, but rather that England was settled #continuously. This is supported by #oxygen #isotope #analysis of human #teeth.

Proud to be on this publication in GCA by Barbora Krizova et al. We show #clumped #isotope reordering in #Cretaceous rudist bivalves is location-specific. Understanding burial history is essential for selecting shell material for #paleoclimate #reconstructions. https://www.sciencedirect.com/science/article/pii/S0016703725004193

The #clumped #isotope paleo temperature proxy is one of the most reliable means of temperature reconstruction in #geology. This new study shows that it can be applied equally on various carbonate minerals (calcite, aragonite, dolomite, witherite and siderite).
