Thrilled to share our work is on the cover of Science Advances! From finding the fossil with my father in 2021 to countless hours across synchrotrons worldwide. Huge thanks to @JolfRocks, Nathaly Archilha, Miguel Basei, and @InvertebratePal! science.org/doi/10.1126/scia

#Microfósseis interpretados como rastros de animais eram na verdade algas e bactérias. Material de 540 milhÔes de anos foi reanalisado por meio de técnicas de microtomografia e espectroscopia. agencia.fapesp.br/58058

I just had to share this excellent paleomeme a student made after my lecture on the end-Permian mass extinction

Is #FossilFriday still a thing? Anyway, here’s Burgessia from the MCZ collection at Harvard, imaged with laser- and LED-stimulated photoluminescence. Work in progress with @InvertebratePal

Have you ever seen a 540-million-year-old microbe at the nanoscale? In our new Gondwana Research paper, we revisit classic Ediacaran Brazilian fossils using synchrotron nanoCT. Free access for 50 days authors.elsevier.com/a/1meEc
 Grateful to @SincrotronLNLS @CNPEM @InvertebratePal

Damn, we got a new Corumbella reconstruction before GTA VI Check it out if you're also into the enigmatic Ediacarans: royalsocietypublishing.org/d

Couldn't resist photographing this sample too. Any guesses whose eyes these are?

Missed #FossilFriday, but here's my late contribution! Meet Cloudina, one of my favorite Ediacaran fossils (for obvious reasons haha). These tubular creatures were among the first to produce mineralized skeletons. The top image is a composite from multispectral imaging.

#FossilFriday - Not sure Twitter is ready for such a beauty. Look at this gorgeous fossil sponge đŸ˜±đŸ˜Let me introduce you to Diagoniella cyathiformis (KUMIP 152000) from the mid-Cambrian Marjum Fm., Utah. Thanks for the loan @kunhm @trilolight @nlopezcarranza

Two photographs at the top show experimental tank containing sand and priapulid worms, which have created burrows seen here in cross-section. Arrows indicate direction of movement. Diameter of coin at the bottom of each image is 2.4 cm. In the lower row are two field photographs of trace fossils. On the left, a treptichnid from the terminal Ediacaran of Namibia (Scale bar at top right is 0.5 cm). In the middle, Treptichnus pedum from the early Cambrian of Namibia (scale bar at top right is 5 cm). On the right, a schematic diagram of the T. pedum 3D structure, with solid line numbered arrows denoting individual probe order offset by 20°–40° and a longer dotted line showing general direction of movement.

New paper out in Royal Society Open Science! With @SMughal315 and George Wedlake, we revisit the Proterozoic microfossil record to review what it can tell us about early eukaryote evolution, and how new tools are renewing and enhancing its utility. royalsocietypublishing.org/d

🛑 Writing on our rocky outcrops is wrong, and permanently damages our natural heritage. 🚹 This vandalism risks destroying features like our Precambrian fossils, and at many sites in Charnwood Forest, is illegal. đŸ“· Take only pictures, leave only footprints
