Diverse landscapes with good connectivity between quarries and calcareous grasslands proved to be particularly valuable.

The Mediterranean coral reef, formed by the accumulation of calcareous organisms, is home to more than 1,600 marine species that have been affected by the rise of water temperatures over the last years.

The researchers analysed the isotopic composition of oxygen in a stalagmite formed from calcareous water in a cave in southern Germany.

Among other things, the researchers determined the isotopic and elemental composition of the calcareous shells of plankton.

The permit, which Science has seen, authorized Frey to transport “two boxes containing calcareous samples with fossils, without any commercial value, with the main objective to proceed with paleontological studies” at SMNK.
