Found the end of the rainbow. Its on the M5 just north of Exeter.

PalAss abstract accepted! Here's a cheeky spoiler...

Living sharks have innumerable tiny scales, but their earliest relatives somehow grew larger bony plates. In our new Biology Letters @royalsocietypublishing.org, we work try and out how, arguing they grew by fusing and remodelling spines and scales. doi.org/10.1098/rsbl...

Incredibly proud and also very emotional to see this new paper published in @systbiol.bsky.social. The study was lead by Pierre Cockx, who sadly passed away in July. academic.oup.com/sysbio/advan...

Decay experiments on shrimps provide insight into the fossilisation potential of arthropod appendages www.openpalaeo.org/article/view... 🦐🦐🦐🦐🦐 Out now in @openpalaeo.bsky.social

A phylogeny for Heterostraci onlinelibrary.wiley.com/doi/10.1002/... Very pleased to see this out, and huge thanks to Emma Randle for leading the study and @fossilrob.bsky.social for pushing it through the finish line.

Come and visit @thepalass.bsky.social at the Lyme Regis fossil festival. See if you can beat the odds and become a fossil!

Just added some new functions to treesurgeon github.com/evo-palaeo/t...

Super interesting paper outlining the damaging impact of the 'Gollum effect': researchers who restrict access to resources. Very relevant to palaeo work regarding the gatekeeping of collection material and the harm this causes to science. Worth a read! www.cell.com/one-earth/fu...

Victory for wild camping at the Supreme Court! The verdict is a relief– but Dartmoor remains the *only* place in England & Wales where the public has a right to wild camp Labour must now pass a new right to roam act to defend & extend the public’s access rights www.theguardian.com/uk-news/2025...

Congrats to Yara and team! They reveal that Anatolepis - previously interpreted as the oldest vertebrate with a mineralised skeleton - is not a vertebrate at all! Paper here: tinyurl.com/59sdw7x9 and a nice write up by @guillaumehouee.bsky.social & Philippe Janvier here: tinyurl.com/2u6haac8

Any young paleo workers will be hard pressed to find a better opportunity than this.

Dinosaur on dinosaur action!

It's finally out! Together with Allison Yi Hsiang and @fieldpalaeo.bsky.social, we explored relative homoplasy in a range of bird matrices and introduce a new parsimony measure, the relative homoplasy index (RHI) (1/n) academic.oup.com/zoolinnean/a...

A small bump in case anyone awake at this time can advise on R/C++ debugging... 🧪⚒️💻

I'm disappointed to resign from the editorial board of @royalsocietypublishing.org @royalsociety.org journal Biology Letters. I won't give my time and labour away to an organisation that - through inaction - condones the destruction of US science by one of its own, Elon Musk FRS. 🧪⚒️

An interesting change from reconstructing dinosaurs and other terrestrial animals... My digital restoration and reconstruction of the cyathaspid heterostracan Anglaspis heintzi from our new paper (see below). #FossilFish #DigitalReconstruction #Palaeontology

Hi all. Last chance to apply for @thepalass.bsky.social awards -including the *NEW DOROTHEA BATE AWARD*. This is for an early career person with up to 5 postdoctoral research experience. Details of how to apply here: www.palass.org/awards-grant...

🥳 We would like to share a newly uploaded video on the #PalAss YouTube channel: 🎥 Palaeontologists Explain: How Do Fossils Form? ⬇️ 🔗  www.youtube.com/watch?v=LwF7... #palaeontology #fossil #youtube #video #channel #new

Very proud to be featured alongside other excellent early career scientists in a new video by @thepalass.bsky.social! We talk about how fossils form and how rare they are! youtu.be/LwF7qnYFde8?...

Here is a little video I made for @thepalass.bsky.social. Its aimed at GCSE students and ties into the national curriculum. Lots more planned, if you want to be involved, give me a shout. www.youtube.com/watch?v=LwF7... Please share widely, like and subscribe!

Interested in trait evolution and/or connecting micro and macroevolution? The Evolutionary Quantitative Genetics Workshop has returned, now at Mountain Lake Biological Station, VA, June 9-13th! Deadline for application April 4th, 5pm EST. More info here: eqgw.github.io

Job Alert: Senior Research Associate in Phylogenomics @bristolpalaeo.bsky.social researching timing, sequence and phenotypic consequences of rediploidisation following whole genome duplication - comparative genomics, molecular clock and phenotypic disparity methods, with @jameswclark.bsky.social

Check out our new method for summarising BEAST trees. The CCD0-MAP tree gives much more accurate results than MCC tree. It returns the tree that maximises the product of sampled clade probabilities regardless of whether that tree was sampled. Highly recommend :) journals.plos.org/ploscompbiol...

Happy to announce that, as of April, I will be joining @bristolbiosci.bsky.social as a Lecturer and operational lead of the Bioinformatics MSc programme!

This looks interesting BUT... In what way is a hagfish basal? journals.biologists.com/jeb/article/...

Job alert! We seek to appoint a new Lecturer in Evolutionary Biology in the School of Biological Sciences, find out more at the link below! www.bristol.ac.uk/jobs/find/de...

I was today years old when I found this gem of a web app to explore 2500+ color palettes for R: r-graph-gallery.com/color-palett...

Check out the tutorial for posterior predictive simulations on the revbayes website revbayes.github.io/tutorials/pp...

So excited to see this paper finally published! 🥳 This was the main focus of my PhD and demonstrates the application of model adequacy for models of morphological evolution. 1/n academic.oup.com/sysbio/advan...

For #FossilFriday check out this gorgeous fossil insect! This 49 million year old beauty is Pulchritudo attenboroughi, a #beetle found in the rocks of the Green River Formation, Colorado. what's particularly striking about this fossil is the pattern on its wing cases. ⚒️🧪🦀🦑 #evosky

🌟 Exciting news! OPal is live—a new Diamond Open Access journal for palaeontology! 🦐 We welcome traditional formats, hypotheticals, preregistered protocols & multimedia articles. 🦖Together we build a platform for impactful and responsible research! 👀 Visit: www.openpalaeo.org/article/view...

Are you interested in some analytical training in paleobiology and a grad student? Then apply for a place in the Summer School 2025! The call is open as of today. More info can be found here: www.paleosynthesis.nat.fau.de/index.php/ap...

This! And bear in mind if you are in palaeontology, there is a curated list on the Palaeontological Association website: www.palass.org/careers/phd-...

This is the official account of The Palaeontological Association (#ThePalAss) on Bluesky. Our association was founded in 1957 to promote the study of #palaeontology and its allied sciences. Learn more: www.palass.org We hope to find old and new friends here!

Latest from the Lab: Madleen Grohganz, with little help from her friends, shows that contrary to expectations of a filter feeding ecology, the oral plates of heterostracans exhibit evidence of microstructural adaptation to a mechanical function. Who knew? onlinelibrary.wiley.com/doi/full/10....

Hi all I'm Joe. I like phylogenetics, morphology and old dead fish. Will be posting sporadically about all three.
