Peer reviewing bullying is definitely prevalent in palaeontology where the subcommunities can be very small. I've seen several reviewers weaponize their peer reviews to gatekeep or protect their own hypotheses. Such a shame for the community! I hope this paper can help.

It is time to talk about peer review bullying. In a new paper, I discuss why this type of bullying is prevalent and how to prevent it. Editors and reviewers, please read this. @CellCellPress @Trends_Ecol_Evo @FGSE_UNIL @unil @snsf_ch authors.elsevier.com/a/1jy2FcZ3X056k

Very nice! As a sidenote for the interested, chordates are also known (but not yet described) from the Sirius Passet Lagerstätte, another early Cambrian deposit from Laurentia. It was mentioned briefly in our latest giant chaetognath paper: science.org/doi/10.1126/sc…

Nuucichthys joins a very exclusive group of Cambrian (stem-group) vertebrates known from sites with exceptional preservation from North America (Metaspriggina, Emmonsaspis) and China (Myllokunmingia, Yunnanozoon), thus increasing the diversity of these extremely rare organisms

A guide to the Palaeoscolecida and my thoughts on collections-based research as a curator, in anticipation of our new paper 🪱😁


Another enjoyable walkthrough of their new worm-paper by @KNanglu!

For a perfect #WormWednesday, @InvertebratePal and I can introduce our newest species Selkirkia tsering! This worm is from the ~475 million year old Fezouata fauna, and has important implications for how we understand early animal diversification! tinyurl.com/3p3m5yh2

1/3 Bullies exist in academia, often targeting ECRs & marginalized communities (from peer review to public attacks, even insulting emails). Diverging scientific opinions are fine, but let's not blur the line between criticizing science & the scientist.

Whoop whoop! Great study just out by my postdoc Valentina Rossi, using high-tech analyses that show the soft tissues in this fossil reptile are not original. Great work Valentina! @thepalass @iCRAGcentre @IrishFossils @uccBEES @UCCResearch

Mystery solved: the oldest fossil reptile from the Alps is a historical forgery. Congratulations to Dr Valentina Rossi @uccBEES on this extraordinary research finding published in Palaeontology. ucc.ie/en/news/2024/m…

Here is a new painting from me... Meet Timorebestia koprii, a giant (~30 cm long) chaetognath from the early Cambrian (approx. 520 mya) Sirius Passet biota, North Greenland: science.org/doi/10.1126/sc… #SciArt #SciComm #PaleoArt #PalaeoArt

Great walkthrough of Sirius Passet and our newly published giant stem-chaetognath, Timorebestia koprii by @Tupandactyl 👇💫

Finally, I was able to tell about this guy! Please give the monstrous new Cambrian weirdo a big round of applause. Here's Timorebestia koprii, a cuttlefish-sized the largest chaetognathiferan found in North Greenland! (1/15) science.org/doi/10.1126/sc…

For #FossilFriday, Kerygmachela’s holotype. When it was first described, small bumps on the sides of the trunk were thought to represent walking legs, but with the discovery of Mobulavermis, its more likely these represent muscles that controlled the flaps. 📸 by @SiriusPalaeo

My paper, describing a new genus and species of lobopodian, has just been published. Mobulavermis adustus is a large relative of Kerygmachela and Utahnax. For those who can't access the paper, I will the findings summarize below. 1/9

Unfortunately my postdoc mobility proposal got rejected by the @snsf_ch The project is too good not to pursue especially with the huge dataset I have at my disposal and the great collaborations established to undertake it. Does anyone have suggestions for where to get it funded?

🚨📄 Paper Alert 📄🚨 Our new paper about the early developmental stages of a 480 million years old arthropod from Morocco is out! We used synchrotron X-ray microtomography to see details of these ~ 2 mm long babies. Details in 🧵👇 1/7

Help me unlock this achievement, I only need to review one more paper! My expertise is Early Palaeozoic Lagerstätten and their fossil assemblages (palaeoecology/biostratinomy) and taphonomy (esp. phosphatization), and early arthropod palaeobiology.

As of today I have reviewed more manuscripts than the ones I’ve authored. I am officially… a reviewer

1/2 The situation in Lebanon is alarming. The political class is using hate speech against the LGBTQ+ community to divert citizens' attention, while daily armed clashes and assassinations intensify societal divisions in a complex regional geopolitical context.

🚨🚨 Paper alert! I am happy to share my new paper with @PGueriau and @cambriancritter 🥳. The paper talks about the suspension-feeding radiodonts from the Fezouata Shale 🇲🇦. Spoiler: Aegirocassis was not alone. Check out the link if you want more details bit.ly/47B1W9k

🚨 NEW PAPER ALERT 🚨 In this paper, we (@glpcjd, @Sansom_Rob, Davide Pisani and myself) use simulations to explore the impact of the pattern of data loss caused by fossilisation on perceptions of morphological disparity. Very excited to see this out! royalsocietypublishing.org/doi/10.1098/rs…
