Can't share pictures of the show itself yet -- as it's not even open! But me, Tone and Em went to LightRoom London today for a #DiscoveringDinosaurs event. Great to bump into @formorphology.bsky.social and @macroecoevoale.bsky.social :) Great selections of books and more in the shop.

After a great icebreaker kicking off the annual @eavpalaeo.bsky.social meeting in KrakΓ³w, I'm finally digging into a fantastic first session. If you're interested in sauropod macroevolution and new relevant insights on Opisthocoelicaudia, don’t miss my talk on Wednesday at 12:15 πŸ¦•πŸ”₯ #EAVP2025!

A study in Nature Ecology & Evolution combines fossil occurrence data, phylogenies and climatic niche modelling to explore the palaeobiogeography of early pterosaurs and their non-flying close relatives, the lagerpetids. go.nature.com/44mbnJY #Paleosky πŸ§ͺ

The short answer? Even after removing up to 98% of species and distorting the data, the LBG signal remained detectable. That’s good news for using fossils to study deep-time biodiversity!

Sofia simulated how various fossil biases, from geology and biology to anthropogenic sampling, might affect the detection of macroecological patterns like the Latitudinal Biodiversity Gradient (higher species richness at the equator, decreasing toward the poles) in modern mammals

New day, new paper! 🦣🌍 Led by @mapaslab.bsky.social ab.bsky.social PhD student Sofía GalvÑn and out now in Global Ecology and Biogeography in which we asked:

"Could future palaeontologists detect today’s biodiversity patterns from fossils alone?"

Really happy to see this out! Also super grateful for Jeff bringing me on board; what started as a casual conversation over lunch in the NHM staff room has turned into some really interesting work and a great friendship. What more can you ask for?!

Great to see Lewis Jones received his Doscar as one of the winners of the 2025 Dorothy Bishop Prize for his work on the Paleoverse (palaeoverse.org) a community space improving reproducibility in palaeobiological research.
