Deoxygenation levels similar to today’s played a key role in marine extinctions during a major past climate change event, according to new @TCD_NatSci research led by Prof. @micharuhl that underlines the fragility of marine ecosystems.

Our work in @NatureGeosci has been published. We use Mo isotopes to show that de-oxygenation levels during the end-Triassic extinction were similar to today with localised marine redox change having catastrophic effects on biodiversity @London_NERC_DTP https://t.co/KWmQQsuVRl

First PhD paper published and now available to view online. Our study makes a link between oxygenation of sedimentary pore waters and biodiversity of infaunal organisms within the Larne Basin during the Late Triassic. https://t.co/LJFVhoNyfy

@WalleyGeology Thank you! I have uploaded the accepted version to research gate if you are interested! 10.13140/RG.2.2.22685.38886

[Andrew D. Bond @AndrewBond8]

Thrilled to say that my first PhD paper has been accepted in Palaeo3! Our study analyses fine scale redox changes through the Triassic/Jurassic transition of the Larne Basin and their potential effect on local biodiversity.

Want to read an insane tenure denial story? I was denied tenure at MIT in 2018. I was the only Hispanic faculty at my department, had 13k+ citations, 2 books, & papers in Nature, Science, & PNAS. I was never given a reason & the only letter I got told me to check the website./1🧵

Our new paper detailing end-Triassic extinction (#ETE) Polycyclic Aromatic Hydrocarbons (#PAHs) is out now! Results find the initial CIE in the SW UK is unrelated to fire activity and soil erosion is a more prominent feature during the extinction horizon

Our recent paper on the origin of arthropod exites has been nominated as one of the 50 best recent papers in the field of ecology and evolution by Nature!! You can find our paper and more nominated research via the links below: https://t.co/r2xqJD5Lgb

This paper by researchers including @JulienKimmig is a very exciting discovery of a wide diversity of juvenile Cambrian organisms. The knowledge we will gain about how these early creatures grew and developed is going to be amazing.

It has been a pleasure to work on this paper with researchers at YKLP, NHM & LMU Munich. Our paper documents the discovery of exites in artiopodans and megacheirans from the Chengjiang biota and makes interpretations regarding exite origins @NHM_London @LMU_Muenchen @NatureComms

[Nature Communications @NatureComms]

This study uses microtomographic imaging of the Cambrian arthropod Leanchoilia to reveal a previously undetected exite at the base of most appendages, suggesting a deeper origin for exites in arthropod phylogeny. https://t.co/2tnkTNX6w6 @AndrewBond8 @RHULEarthSci

First thing to do tomorrow morning: reading a paper claiming that some trilobites inhabited brackish-water environments... 🤓🧐 https://t.co/cE9xW2EV3Q

This is a detail of a larger illustration that I am preparing for my book depicting the early pterosaur Arcticodactylus from Late Triassic Greenland. It is still a WIP. #Pterosaurs perched on vegetation are among my favorite things to depict. #paleoart #sciart

[Rudy Lerosey-Aubril @PlLife2]

🚨🚨🚨 New paper by former colleague J. Paterson et al. that I got the chance to review. Look at these beautiful anomalocaridid 👁️. The preservation is pristine and so little is known about vision in this group that includes Cambrian apex predators. https://t.co/mwLCAlENTC

[Dr. James Lamsdell @FossilDetective]

There's an excellent new paper out describing the eye structure of #fossil stem #arthropods - revealing a diverse set of visual ecologies among anomalocaridids.

Also, isn't it high time that 'Anomalocaris' briggsi got a genus name of its own?

Approaching the end of a 90 sample digestion. Looking forward to seeing what elemental data can tell me about marine redox and hydrography from these late Triassic sites!

@lukas_laibl That's almost certainly a naraoiid. As you say it's v. dubious. It would be nice to find a definitive Moroccan specimen, even if part of an existing morphotype, just to fill the gap in the Ordovician. So far there is only N. hammanni! Gozalo, 2018's Spanish specimen also dubious!

[Andrew D. Bond @AndrewBond8]

Thrilled to see that some of the unsampled liwiid diversity is finally being discovered and published! Can't wait to see what new nektaspids can be discovered from sites like these!

Meet Tariccoia tazagurtensis - a new #arthropod named after the city of #Zagora (#Morocco) - in #Tamazight language, Zagora is called Tazagurt (ⵜⴰⵣⴰⴳⵓⵔⵜ). #FossilFriday #Amazigh
