A new perspective, sparked by studies of pterosaurs, argues that documenting fossils and anatomy is essential science in paleontology—even without testing formal hypotheses. archosaurmusings.wordpress.com/2026/03/23/i... #fossils #paleontology

A handful of volcanic eruptions are occurring on Earth at any given moment. But those events, impressive as they may be, still pale in comparison to the volcanic activity associated with large igneous provinces (LIPs). eos.org/articles/vol...

Aeolian sand transport doesn't follow a single scaling law. In a new Open Access Geology study, Peng Wang, Hans J. Herrmann, and Ning Huang present a unified theory explaining linear flux from wind drag and collisions, and nonlinear flux from grain contacts. Read more: geosociety.co/sandflux

"Dear Dr. Samuele Papeschi, We are delighted to inform you that your manuscript titled "P-T modeling constrains the depth of emplacement of the Porto Azzurro Pluton and implies minor exhumation caused by the Zuccale Fault (Island of Elba, Italy)", has been accepted for publication in JMG."

Great CT sedimentary basins field trip today at #NEGSA2026, led by Paul Olsen. Saw some turbidities and ash beds and tried (and failed) to find fish fossils. Started at Dinosaur State Park where I’d not been before, and encountered this fish who is a Whole Mood!

Amazing trace fossil - Zoophycos - from the mid-Miocene sediments of the Tabernas basin, Almeria. First time to have seen this, in many years of field visits - spotted by eagle-eyed 3rd year @oxuniearthsci.bsky.social students. ⚒️

🌟OPEN ACCESS🌟 Opposite Faulting in Global Seismicity #TSR Sometimes, earthquakes with seemingly implausible opposite source mechanisms occur together. This is strange because their strain variations should act against each other. What might be going on? ⚒️ buff.ly/HtrvFh4

I have an ichnologist joke, but I couldn't track it down.

I downloaded this Sentinel-2 scene to get a closer look at infrastructure burning at Bandar Abbas, Iran. But these crazy folds and a salt dome nearby are way cooler. 🛰️🖼️

A few weeks ago CBC reporter Sheena Goodyear reached out to me for comment on the new Spinosaurus paper. I said I couldn’t, because of Epstein connection Nathan Myhrvold’s involvement with it. We got to talking about how paleontology - especially dinosaur research- remains hostile to women. 🧪

The Amazing World of Tomorrow

It is *fascinating* to me how quickly some people have gone completely from “we all must work in the office! human collaboration is vital and only happens in person!” to “I can replace all these pesky people with chatbots!” Definitely some commentary there about our society and who gets to choose.

Brazilian scientists have identified a new giant dinosaur linked to a species in Spain, suggesting land routes once connected South America, Africa and Europe about 120 million years ago. www.reuters.com/science/dino... #fossils #paleontology

Another academic who does not have the slightest grasp of what the point of being a professor is. Anyone who views graduate students as hired labour and as means to serve their own goals should not be advising students at all. Shame on Science for platforming this. www.science.org/content/arti...

happy #fossilfriday! bonus: this is psephoderma, a placodont from late triassic europe. placodonts were sauropterygians – meaning that they were related to pliosaurs and plesiosaurs – with distinctive teeth well-suited to crushing the shells of molluscs (art by ntvtiko)

Happy with the publication of this paper in which we demonstrate dietary responses to dry climate in extinct Gomphotherium based on the chemistry of their teeth. A very nice collaboration with Spanish and Portuguese colleagues, with more opportunities in the future! bg.copernicus.org/articles/23/...
