<i>Corsiniopsis kurtzii</i> gen. Et sp. Nov., a new fertile marchantioid fossil from the late triassic of argentina provides evidence of the evolutionary trends of fertile branches in the complex thalloid liverworts

through the description and analyses of a new Early Mesozoic fossil, our study reveals a novel trend in the evolution of specialised fertile branches in Marchantiales. Likewise, according to our time-calibrating, the radiation of xerophytic lineages is inferred older than in previous studies. Our study highlights the importance of discovering new fossils to close the gap in our knowledge of the evolutionary history of the complex thalloid liverworts.
