A shift in organic carbon-to-total phosphorus ratios in marine siliciclastic strata from approximately 455 million years ago suggests an earlier-than-previously-thought spread of land plants and their impact on the Earth system 🧪 www.nature.com/articles/s41...

Delighted that our new paper on #Ediacaran early animal life is now out rdcu.be/fnksl @natecoevo.nature.com We show that asexual reproduction, stoloniferous reduces competition for Ediacaran early animals 580-560 million years ago, and that this then reduces early animal diversity
Remarkably modern marine fish assemblages were established in the tropics within 4 Myr of the K-Pg extinction.

Animals were much more severely affected, losing over 60% of their diversity. Importantly, these extinction patterns were not uniform; These extinctions were uneven across latitudes and regions, showing strong geographic variation.
Our new preprint
On a global scale, plants did not experience a catastrophic mass extinction during the Permian–Triassic boundary (PTB). However, they still suffered losses, with extinction rates reaching around 30%. doi.org/10.64898/202...
