New insights into the extinction and recovery of marine vertebrates across the Permian–Triassic mass extinction event in the Dolomites, Southern Alps, Italy

The impact of the Permian–Triassic mass extinction on marine vertebrates is incompletely understood due to their scarce fossil record. To better understand marine vertebrate extinction and recovery...

🎉Congratulations to Charlotte, Kate, Amy and Lydia - 4x members of DeepBio@Leeds who've fledged to new adventures! Super proud of you all 🥰

After 3 years of hard work, fantastic travels and ridiculous stress my PhD is done. Graduation was lovely and I am officially a Dr 🎉 Big shout out to my family and my wonderful supervisors for all their support ! @mariabeger.bsky.social @profalexdunhill.bsky.social @universityofleeds.bsky.social

🚨📄 NEW PREPRINT ALERT 🚨📄 🌐 Are we mapping ecosystems… or just mapping models? 🤔 We took ONE Jurassic fossil community 🦑🐚🐟 and built food webs SIX different ways. The result? 😳 The way you build the network can matter MORE than the change you're trying to study. 🔗 doi.org/10.32942/X2X... 👇

The end-Permian extinction 252 million years ago wiped out over 80 per cent of marine species, but many ecosystems still had complex food webs despite the losses

Top predators still prowled the seas after the biggest mass extinction

Congratulations to Dr Kate Simpson on passing her PhD viva with only editorial corrections & a commendation for research excellence! 🎉🍾🏅 Kate has been bridging the gulf between poetry & palaeontology for her PhD work & it's been so much fun working with her these past few years. So proud of her!

Congratulations 🍾🎉 to Dr Lydia Woods who past her PhD viva yesterday! So proud of you! Thanks to Simon Darroch and Paul Wignall for the examining - a great time was had by all. @palaeoleeds.bsky.social

Congratulations to Dr Charlotte Clay who has passed her viva with flying colours and very minor corrections! 🪸🎉

PGRs Amy Shipley (@sauropodlets.bsky.social) & Lydia Woods recently published a review in @globalchangebio.bsky.social showing that while today’s extinction rates aren't yet at "Big Five" mass extinction levels, they’re likely the highest seen in the last 66myrs. amdunhill.co.uk/2025/11/17/n...

Congratulations to Dr. @ming-tfk27.bsky.social who had her PhD Viva today (and generously gave a public talk on zoom). So proud of her and her work on fossil and recent life in Antarctica, some of which even brought her back to PRI. #fossilfriday ⚒️

Waiting for my flight back to the UK at Oslo airport. Had a great time visiting @lhliow.bsky.social and her group to give @thepalass.bsky.social Innovations lecture. Oslo is so nice!
