Understanding the formation of iron-rich banded rocks
Until now, scientists have considered the absence of microfossils and the low level of organic carbon in banded iron formations, deposited between 2 and 3 billion years ago, to be […]

New book on the paleontology and evolution of invertebrates
Invertebrate animals are essential groups in paleontology, due to their abundance in the fossil record and the diversity of their anatomical planes. Recognizing them and understanding their evolution is therefore […]

New method measures retreat of coastal cliffs over several millennia
If we are to assess the recent retreat of coastal cliffs through erosion, we need to be able to know their trend over longer periods of time, something that has […]

The carbon footprint of research infrastructures challenges the environmental responsibility of INSU laboratoires
To limit global warming to less than 2°C, it is necessary to radically reduce current greenhouse gas (GHG) emissions. Scientists should also participate in this effort as part of their […]
