PhD student in Devonian paleobotany @UniversiteLiege, Research assistant in Triassic paleobotany at the Swedish Museum of Natural History🌱🌲🌺🌿🌍
In May and Jully 2025, I presented some new results from my PhD dedicated to the Latest Famennian flora of Euramerica🌿 in the Swedish Museum of Natural history and at Agora Paleobotanica in Paris. At Agora, I was awarded the Boureau Prize for the best oral presentation. 😄🏆 #Paleobotany #Devonian

#Botany Enjoy some lovely ferns lato sensu and lycophytes found within the lovely spruce forest of Tyresta national park (Sweden).

#FossilFriday 🌿 Meet Cephalopteris and its Belgian relative Rhacophyton! By the end of the Devonian, these early ferns, with planated but unlaminated ultimate appendages, were among the euphyllophytes converging on leaf evolution. #Paleobotany #FernFriday

#FossilFriday #Paleobotany The Late Triassic flora of Bjuv provides a unique window to represent early Mesozoic vegetations and their evolution through one of the least known mass extinction crises, the T-J boundary. Below are the Bennettitalean Anomozamites and a seed-fern called Pachypteris.

A #FossilFriday dedicated to the Permo-Carboniferous sphenophytes that once flourished in riparian forests and mires. Here is the pith cast of a giant Calamites alongside the stunning whorled wedge-shaped leaves of Cathaysian Sphenophyllum. #Paleobotany #Palaeobotany 🌿🌱

#Paleobotany In the shade of the Archeopteris trees that overhang them, Rhacophyton condrusorum flourished in the Late #Devonian understory of Euramerica. These not-yet-leafed vascular plants are thought to be the precursors to the successful filicophytes, living alongside the earliest seed plants.
