Revealing fossil anatomies and preservation pathways using advanced imaging techniques
As of today I am starting a 2-year contract as Junior Lecturer (“Premier assistant”) in Palaeontology at the Institute of Earth Sciences of the University of Lausanne. I will be helping with the teaching of palaeontology, mostly practicals but will […]
Worms, arthropods, vertebrates: all terrestrial fauna has an aquatic origin. As far as vertebrates are concerned, including us humans, the water-to-land transition began about 400 million years ago. It is among the sarcopterygians (aquatic vertebrates with lobed fins, as opposed […]
The fur of various mammal species has been discovered to glow in shades of red and pink when illuminated by ultraviolet (UV) lamp, through a phenomenon known as photoluminescence. In UV-photoluminescence, UV light is absorbed by a substance and reemitted […]
A new adventure starts for me today, back in Paris! I am returning to the Muséum national d’Histoire naturelle as a Research engineer (short-term contract), appointed to the European research platform IPANEMA dedicated to ancient materials (Gif-sur-Yvette). I will be […]
The invasion of land by animals, followed by the establishment of complex continental ecosystems, is a critical event in the history of life on our planet. Nonetheless, little is known about most of the pivotal morphological and physiological adaptations imposed […]
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 […]
