Happy to have participated to the XII EPPC in Münster, the first conference together with my two Doctoral Students, and the whole paleobotanical Senckenberg Frankfurt team! I am so proud of the great work that my students have presented!

Today the organisers #SAPP2026 have gone to schools in Trelew to talk to the pupils about what a scientific conference is and why fossil plants are important to understand our past and future. What an amazing way to reconnect people to their paleontological heritage, we have much to learn from them!

On my way to the Simposio Argentino de Paleobotanica y Palinologia in Trelew! Looking forward to seeing many amazing talks and meeting fascinating people! #SAPP2026

a cute little fossil fern for this #FossilFriday. This picture was taken by illuminating the fossil with light in the visible spectrum and capturing the infrared radiation emitted from the specimen!

A beautiful set of branches of Archaeopteris, one of the first globally distributed trees, it's ideal for #FossilFriday!

given the deluge of new followers, a new introduction is appropriate: I am a palaeobotanist with a passion for fossil leaves of all kind, but expecially cycad leaves! Other interests include supporting plant paleoart, TTRPGs, food, beer and wine! I also sometimes write on my blog mariocoiro.blog

the results? Cycad morphological space continued to expand after the Jurassic, and its position continuosly shifted through time. Extant cycad leaves are not a leftover of a great past diversity, but rather continue to evolve and diversify up to the present!

we used morphological data for fossil and extant cycad leaves, the fossils that started the whole 'living fossil' idea in the first place, and employed a phylogenetic tree that we generated last year with Fabien Condamine, Remi Allio, and Nathan Mazet

I am positively impressed by the National Botanic Gardens in Dublin! Their cycad collection is quite stunning, and their Wood's cycad is healthy (and huge!) 🌱🌾🧪

I just discovered that one of my botanical 'heroes', Agnes Robertson Arber, published her first paper on cycads! She was a botanist and philosopher of science with a unique an deep perspective on science, and it is an honor to have her amongst the ranks of the cycadologists!

I agree, Cycadales are heavenly. Though one could argue they are equally hellish...

Hi, I am Mario, a paleobotany postdoc currently in Vienna. I work on seed plant macroevolution integrating fossils, phylogenies, anatomy, and ecophysiology.

since I am starting to be active here, an intro is due: I am a postdoc in Paleobotany in Vienna, working on plant macroevolution with a focus on late Mesozoic seed plants (with a particular fondness for Cycads) . I am also into beer, wine, board games, food, and music.
