Revealing fossil anatomies and preservation pathways using advanced imaging techniques
Even the most spectacularly preserved fossils, with soft tissues ‘petrified’ as the product of a complex interplay of biological and geological processes, have experienced alterations that distort palaeontological reconstructions. Many works have now emphasized the need to precisely constrain these […]
A paper long in the making, which I led while a postdoc at SOLEIL and IPANEMA, is finally published today in the journal Geology. In this article, I investigated exceptional preservation through phosphatization from a fossil perspective. Soft-tissue phosphatization, i.e., […]
In a paper led by Farid Saleh (University of Lyon) and published this month in Geobios, we provide insights into soft tissue taphonomy in the Fezouata Shale based on a detailed sedimentological investigation constraining the facies in which exceptional preservation […]
In a paper published today in the Journal of Synchrotron Radiation, to which I collaborated while a postdoc in IPANEMA, we developed a robust framework and software implementation for fast speciation mapping. One of the greatest benefits of synchrotron radiation […]
A new paper, to which I collaborated while a postdoc in IPANEMA, is published Open Access today. Using an advanced synchrotron imaging method called Ptychographic X-ray Computed Tomography our international team of scientists from Brazil, France and Switzerland has obtained […]

Initiated in collaboration with Linda Lagebro (Uppsala University, Sweden) during our respective PhD projects, a paper describing eurypterids (‘sea scorpions’) from the Upper Devonian aquatic continental ecosystem of Strud, Belgium, is finally published this week in Geological Magazine. The material […]
Born from an impropbable discussion at the Stanford synchrotron 3 years ago, my colleagues and I are publishing today in Science Advances (Open Access) a promising new technique for studying the chemical nature of carbon in 2D or 3D in […]
Two new articles, to which I collaborated while a postdoc in IPANEMA, are published Open Access today. Based on the anatomical description of fossils using advanced imaging techniques, partly synchrotron-based, they provide new insights into the origin and evolution of […]
