Climate change has resulted in salty groundwater in Iraq’s ancient Babylon, which is corroding some of humanity’s earliest structures. Now, archaeologists are preserving locations that were previously regarded as one of the world’s wonders using low-salt mudbricks created by a local craftsman.
An multinational team of experts from the Natural History Museum, UCL (University College London), the University of Florence, and the Swedish Museum of Natural History discovered a unique sort of fossilisation that had previously gone unnoticed.
The ‘ghost’ fossils are imprints of coccolithophores, which are single-celled plankton. Their discovery is altering our understanding of how climate change affects plankton in the oceans.
