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...

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...

New paper in press on a Late Devonian fossil plant assemblage from Australia, with lycopsids (Leptophloeum), cladoxylopsids (Denglongia), and progymnosperm (Archaeopteris/Callixylon) remains 🌿⛏️ #paleobotany #FossilFriday doi.org/10.1016/j.pa...

Our new paper is online! We found that 1) today's shark & ray diversity was already reached ~100Ma; 2) that the K/Pg extinction was not catastrophic; 3) that the max diversity was reached ~50Ma; and 4) that today's diversity is depleted compared to the past. www.cell.com/current-biol...

New paper by @pimientoc.bsky.social & team: #biodiversity of sharks and rays over time. As predators they shape marine ecosystems. Many of the ~1200 living species are in danger, mainly from overfishing, and in need of conservation action. more on shark conservation👇 www.cell.com/current-biol...

Excited to share our new investigation of Prototaxites! We found no support for a fungal affinity and instead suggest it is best considered an entirely extinct complex eukaryotic lineage Great team effort @transitionalform.bsky.social Corentin Loron, and many others! www.science.org/doi/10.1126/...

Our paper on the mysterious Devonian organism Prototaxites has now finally been published! See the paper here (www.science.org/doi/10.1126/...) and our explainer thread below! Prototaxites reconstruction by Matt Humpage

Contingent responses of diversity and disparity of different animal groups to the P-Tr mass extinction: "Ammonoids...brachiopods exhibit refilling of vacated morphospace of shell outlines, Ostracods underwent adaptive radiation" www.sciencedirect.com/science/arti... 🧪 #Geology ⚒️ #Paleobio #EvoBio

Why does life explore so few of the forms it could possibly take? Using fractal descriptors, this #scienceadvances paper shows that Earth’s biosphere clusters around simple shapes, reflecting deep evolutionary constraints. @artemyte.bsky.social @manlius.bsky.social www.science.org/doi/pdf/10.1...

We are very pleased to share our new research, investigating the morphology of Zosterophyllum.

A 407-million-year-old fossil from northern Scotland is changing what we know about plant evolution! New analysis of Horneophyton reveals how plants went from centimetres tall to growing to enormous heights! Find out more about this fossil 👇 www.nhm.ac.uk/discover/new...

Excited to share our new paper where we find that the rise, decline and fall of clades is not explained by the usual suspects (diversity-dependence, ecological opportunities) but rather by species' insidious loss of macroevolutionary fitness: www.nature.com/articles/s41... 1/3

Excited to share our research on the evolution of fossil forests from the Devonian to Jurassic! By analyzing 38 global fossil forests, we explored key parameters to better understand how these fossil forests developed over time. doi.org/10.1016/j.ea...

Is it a lizard? Is it a snake? Maybe a 'false snake'?? As that's what its name means in Gaelic! Hello to Breugnathair, a new fossil from the Jurassic of Skye with a curious mix of snake & lizard features, showing that early squamate evolution was complex www.bbc.co.uk/news/article...
