Phylogenetics, bryophytes and fossils 🌿🪨... and a bit of music and rock climbing 🧗‍♂️🎸
Excited to share our latest paper — we describe Corsiniopsis kurtzii, a fertile marchantioid fossil from Argentina that sheds light on the evolution of xerophytic lineages and their unique reproductive traits. #FossilFriday #bryophytes

Unfortunately, Carmen´s landscape didn´t make it to the final version of the paper, but it still conveys one of the main points of our study... early non-vascular land plants probably looked like extant Marchantiales.

In that paper, we inferred a Silurian-Devonian origin for Marchantiales - instead of Permian as estimated with molecules alone.

We also found evidence of morphological stasis, an #evolutionary pattern characterised by a lack of morphological changes, which lasted nearly 200 Ma. 👉

This hypothetical liverwort was inferred as part of a #phylogenetic dating analysis of the complex thalloid liverworts based on #fossils, morphology and molecules that was published in @newphyt.bsky.social back in 2023

I was checking some "old" files and came across this beautiful Devonian landscape by Carmen F. Ulivarri (ig: @ilustra.botanica.uel).

It showcases a hypothetical "ancestral" #bryophyte – a tiny Blasia-like liverwort, that had pretty much the same features of modern simple thalloid liverworts. 👉

Our new paper on the #phylogeny of Osmundales is out. We reviewed the phylogeny of the group by taking into account character dependence and found that most of the recognised groups are hardly when dependencies are ignored. Check it out
