Weirdly enough, that skull seems to be from Aenigmatorhynchus and corresponds to a paper published last June (doi.org/10.1098/rsos...). The journal seems to collect potential cover images from authors and then use them for an unrelated volume published later on
When I started my PhD ~10 years ago, only 2/5 echinoderm groups (the star-shaped sea stars and brittle stars) had genome-scale phylogenetic datasets. I am proud to say that the quest to complete the clade is now over

Becoming a part of the @systbiol.bsky.social community is one of my greatest scientific achievements. I am happy to celebrate this today with a journal cover and a nomination to the editorial team
Spring is here
Our latest paper, now how to conciliate apparently discrepant evolutionary rate patterns in squamates, but which may well apply to any study system with Stephanie Pierce and

I am extremely happy to see that our review on fossil tip-dating is out in early view in Systematic Biology! A huge thanks to all the authors of this massive project (@heckeberg.bsky.social, @basantakhakurel.bsky.social, Gustavo Darlim, and @hoehna.bsky.social)! academic.oup.com/sysbio/advan...
Seeing these after laying down the first volume of Fabre’s Souvenirs entomologiques, devoted to the rearing behavior of predatory wasps, was a treat. Thanks for sharing Marshall!
I use it all the time, along with mean()

Today I learned the (very) hard way that R will tell you a file does not exist even when it totally does if the path to it exceeds 260 characters
(in Windows)
(and you can enable long paths, but it is not the default)
I will forever despise whoever named some closely related echinoid genera with a name starting with “Paleo” and others with a name starting with “Palaeo”
A Sunday reading Fabre’s “Souvenirs entomologiques” by the fireplace is a Sunday well spent
Actually, I got it wrong, it is -3. I was going with alternating between subtracting -2 - (i - 1)/2 and adding 1, where i is the iteration
Following the sequence would make state 5 = -4 median eyes
A student once asked me why wasn’t I using which.min(x) instead of which(x == min(x)) and I pretended it was for pedagogical purposes
Congratulations James! That’s outstanding
And this breakthrough required only.. how many months in Berlin??

Yeah, it is true that the result deviates from the expectations of ordering variables/observations. If the matrix format that sapply outputs isn’t convenient you can use lapply instead, or you can just transpose it
I think this is because you are not supposed to use sapply on matrices. If you do it probably gets coerced into a data.frame, whose elements are the columns.
Anyways, not long ago I discovered asplit() which is pretty handy when needing the flexibility to work across either margin
Sleep Token is horny metal?? 😆 @brenenwynd.bsky.social what are your thoughts on this?
Redefining music 25 years after your debut album is something that was probably done only once

I'm recruiting a PhD student to join my lab at the University of New Orleans starting in Fall 2025. Research topics will focus on building and using phylogenies to study the diversification of birds, with an emphasis on Neotropical bird radiations. Contact me if interested.
Great news!! Congrats 🥳
I finally have something worth posting here! A new paper on wormsI never expected to see fossilised! Juracanthocephalus is the first body fossil of Acanthocephala and remarkably provides links with rotifers and other gnathiferans.
