This #FossilFriday I am delighted to share a postdoctoral position that we @deeptimeecology.bsky.social @camzoology.bsky.social are advertising on early animal evolution in the #Ediacaran. www.cam.ac.uk/jobs/postdoc...

LAST DAY for the Sea Star #CoralSeaFrontiers workshop-Over 211 specimens, about 60 different species, maybe 20% of those? were undescribed! (but I did just publish a new paper on New Caledonia!) my thanks to @oceancensus.bsky.social @drtimohara.bsky.social for supporting this visit and ID workshop!

#NovaScotia scientists dive deep into the province’s coastal biodiversity Members of the Canadian Parks and Wilderness Society’s Nova Scotia chapter (CPAWS-NS) are freediving to understand life beneath the waves. www.ctvnews.ca/atlantic/nov...

Tardigrades in Space Wikipedia page. I thought tardigrades were well known but I once sold #sciart at a microbiology conference & was surprised that there were folks there who had not heard of the mighty tardigrades, so I am happy to introduce you if new to you en.wikipedia.org/wiki/Tardigr...

*laugh* a FASCINATING observation of this sea cucumber, Paracaudina from Australia doing.. something. Blowing bubbles? A great big "WHAT?" #echinoday www.inaturalist.org/observations...

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

This is brilliant.

Greenland sharks grow less than 1cm per year, reach sexual maturity at 150 years old and are the slowest sharks in the world. These deep-sea creatures live to at least 250 years, making them the longest-lived vertebrates on Earth. #DeepSeaWonders

The sleep patterns of jellyfish and sea anemones share similarities with those of humans, according to research published in Nature Communications. The findings support the hypothesis that sleep evolved across a range of species to protect against DNA damage. 🧪

How did these strange, ancient organisms turn into such remarkable fossils? @cambrojoe.bsky.social @egmitchell.bsky.social #evolutionsoup #evolution #cambrian #science #fossils 👇🏿👇🏽 is.gd/AwnRgy

Exciting news! I was interviewed by @currentbiology.bsky.social for their Q & A section, where I talk about the future of palaeontology, dangers of AI in education, social media and science communication. Featuring, my doodles! cell.com/current-biology/fulltext/S0960-9822(25)01552-0

Really excited to have the new issue of Paleobiology @paleosoc.bsky.social out celebrating the 50th anniversary of #punctuatedequilibria #macroevolution #paleobiology #palaeontology #paleontology @nilese.bsky.social www.cambridge.org/core/journal...

Happy New Year! Please pre-register (non-binding) for the 1-3 June #Oslo Larwood #bryozoa meeting! It will help us better estimate conference needs, meaning lower conference fees! There will be ecology, evolution, taxonomy and an in-person Dennis!!! www.bryozoology.org/kopie-von-20... pls repost!

Looking for a PhD in palaeontology or associated fields? Just a heads up that we have a list of opportunities on the @thepalass.bsky.social website: palass.org/phd-opportun... ⚒️🧪🦀🦑 #evosky (If you're advertising one, you can add it to our listings too: palass.org/form/webform... )

Highlights included: 🦞 Leach’s squat lobster (Galathea squamifera) as well as the usual Spiny’s (strigosa). 🍋 Juicy Sea Lemon Nudibranch (Doris pseudoargus). 🪭 A tiny feather duster fan worm (Sabellidae), that was smaller than my pinky nail!!! Pleased with the macro shot i took!!

Felt a little festive at the microscope this morning for #FluorescenceFriday 🎄 Here’s the nervous system of a juvenile sea star ⭐️ Green = acetylated tubulin, red = nuclei Happy holidays!

New paper alert! 🚨 🐌 We studied historic Antarctic fossils from the Zinsmeister Collection to assess whether the K-Pg extinction, as recorded on Seymour Island, was sudden or gradual. We found that benthic life thrived in the 4 million years before the K-Pg. doi.org/10.1016/j.pa...

Incredible festive card from @rachelwarnock.bsky.social and colleagues at FAU - hope everyone has wonderful holiday season!

Fantastic time at #BES2025 @britishecologicalsociety.org talking community ecology past and present! From the early animals of the #Ediacaran time period with modern corals and rainforests

Excited to launch the new improved Reproducible Code guide from @britishecologicalsociety.org @methodsinecoevol.bsky.social FREE online here! www.britishecologicalsociety.org//wp-content/... Amazing work by some very talented ECRs. We hope it’s useful!

A great talk from Yarong about using Bayesian network analysis to reveal multi-scale community dynamics in the Ediacaran Shibantan Biota. #PalAss2025 @thepalass.bsky.social

We are at PalAss in Portsmouth! Princess is presenting a poster on Charniodiscus in the Portland Building, Tara on Avalonian community compositions in the Richmond Building, and Emily is giving a talk on constraining lifespans of Ediacaran animals in the Richmond Building LT at 9.30. Exciting day!

This #FossilFriday I am delighted to say that I have been awarded a @erc.europa.eu Consolidator Grant looking at selection in #Ediacaran animals. If interested in Ediacaran life, do come and chat at #palass2025 @thepalass.bsky.social

This #MolluscMonday here are some great ones from my recent fieldwork in Fiji with Victor Bonito, Reef Explorer Fiji: two octopus watch Victor take video to make 3d models, a clam and a nudibranch. We are mapping out different areas in the reef flats to see how soft corals change through time.

It’s baby octopus season 🐙🦑 Saw this little guy last night with the Salish Sea School in Anacortes, WA as part of their free community dock walk I volunteer as an interpreter for. We can tell it is a giant pacific octopus from the single line of chromatophores on each arm.

#Fractofusus is the most common organism at many of the #Ediacaran fossil sites in #Newfoundland, and it's also one of the best preserved. Here we can see the complex branching they possessed, preserved in exquisite detail. #FossilFriday #FractofususFriday
