New fossil from Belgium sheds light on how millipede predecessors gained ground

October 21, 2020November 27, 2020 PierreResearch, Research papers

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 […]

Synchrotron XRFD mapping published in Roy. Soc. Interface

August 26, 2020October 5, 2020 PierreResearch papers

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 […]

Fossil phosphatization under oxidative conditions

July 31, 2020October 5, 2020 PierreResearch papers

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., […]

Soft tissue preservation in Fezouata fossils

June 30, 2020October 5, 2020 PierreResearch papers

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 […]

Software implementation for fast speciation mapping

June 16, 2020October 5, 2020 PierreResearch papers

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 […]

Unveiling billion-year old life forms with X-ray vision

May 18, 2020May 18, 2020 PierreResearch papers

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 […]

Preprint: imaging mineralization processes across centimetric fossils

March 31, 2020October 5, 2020 PierreResearch papers

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 […]

Remote teaching: implementation of virtual labs

March 22, 2020October 5, 2020 PierreTeaching - UNIL

In view of the current situation, Teaching must be adapted to distance learning. While lectures can be delivered online via live or recorded videos, labs often have to be completely rethought. Yet they can be almost directly transposed in the […]

New publication: freshwater Devonian eurypterids used ‘nursery’ pools

October 8, 2019March 16, 2020 PierreResearch papers

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 […]
