Well twitter, its been fun, but its time to migrate. You can find me on @evopalaeo.bsky.social

Brown Nugget has just finished 20,925,000 ancestral state estimations. 🫡 I realise that without context, this makes no sense.

Making lectures and inserting outdated memes. @RussellGarwood would be proud.

New Paper Alert. @Ella_Nicklin leads our new paper in @Dev_Bio_Journal Evolution, development, and regeneration of tooth-like epithelial appendages in sharks. What do all 'odontodes' have in common? Is a tooth, just a tooth? #sharks #teeth #skinteeth

@NHMdinolab Yes indeed. And that was partly the inspiration for this paper - particularly answering the question: do different coding strategies give different results? I would have thought so, but actually model and outgroups seem to be more important.

[Joseph Keating @evopalaeo]

When did feathers evolve? Are bird feathers homologous with pterosaur tufts? Check out our new preprint, lead by the fantastic Pierre Cockx. We use different models, outgroups and coding strategies to clarify feather evolution.

@sahinmy @nrken19 If you are referring to mammalian hair, almost certainly the former. If you are talking about pterosaur fuzz, our study suggests that it independently evolved from scales, although the minority of models support a single origin of feathers/fuzz, followed by multiple losses.

Happy to share the preprint from part of my PhD thesis.
The work behind this paper was massive and I couldn't have done it without the expertise and effort of my colleagues, collaborators, supervisors and friends!

[James Mulqueeney @JamesMulqueeney]

Super proud to announce my first publication: https://t.co/18AmiiFrYG. A big thanks to all those involved, @jfabrombacher @anjgoswami @tomezard, Alex Searle-Barnes and Marisa Sweeney!

Chuffed to bits with my Diademaspis, one of the first fossils I ever worked on, brought to life by James McKay @YorksFossilFest

In sunny Redcar for @YorksFossilFest this weekend. Found my first fossil already...

@Tweetisaurus @BBCRadio4 @jimalkhalili I've just seen this, I'm fuming, did they do no background research? There are soo many more deserving palaeontologist who they could have interviewed @BBCRadio4 @jimalkhalili

@robinmdbeck I'll add it to the to do list!

Introducing treesurgeon (https://t.co/cEtJmIfqSH), a new R package of tools and tricks for working with phylogenetic trees and data, especially morphology! Here's a few things it can do...

[Joseph Keating @evopalaeo]

This is very much a work in progress and I'm keen to get feedback. Let me know what you think!

[Joseph Keating @evopalaeo]

There is also a function for computing tree to tree distances in parallel using the foreach package. This will allow you to visualise tree spaces with large numbers of trees!
