Work on reef paleoecology? Join our session "Reefs through time: leveraging today's interdisciplinary tools to better understand the past of reef organisms and ecosystems" at the 2026 International Coral Reef Symposium 📆Abstract deadline: Dec 1, 2025 🔗https://www.icrs2026.nz/call-for-abstracts

Very happy to see El Mestel's work on seismicity at Taupō volcano published today in JGR: agupubs.onlinelibrary.wiley.com/doi/10.1029/... El used a new seismic network to look at Taupō in more detail than anyone has done before

Really cool paper looking at the onset/ongoing initiation of subduction of the Caribbean plate beneath the Isthmus of Panama. And another call for the paleo and bio people to deal with North America and South America being in contact with each other since at least the Miocene, not the Pleistocene.*

🌟OPEN ACCESS🌟In a new #BSSA paper, scientists apply a pretrained earthquake detection algorithm to four studies that represent a range of network, tectonic, and environmental challenges. How well did the algorithm do? ⚒️ pubs.geoscienceworld.org/ssa/bssa/art...

HiPOD: A Recipe for Martian Scallops A layer of clean ice lies just below the surface in this image. As the ice ablates away in some spots the surface dust collapses into the hole that’s left. These holes grow into the scallops visible here as more and more ice is lost. uahirise.org/hipod/ESP_06...

I’m ready for a fight: figures belong in-line in manuscripts for peer review. No exceptions.

Meet our brilliant team of Associate Editors! Dr Paul Kenrick is a leading expert on the early evolution of plants 🌿 focussing on soil ecosystem development, plant organ and tissue evolution, and the co-evolution of plants and fungi. Read about his fascinating work: buff.ly/8gV5BKf #NHM #PaleoSky

I was asked yesterday to post a walkthrough of Life Over Time, the shortest-lived and generally weirdest iteration of the Field Museum’s fossil halls. If you visited between 1994 and 2004, this is the version you saw. I’ve got some time, so let’s do this.

#kyanite fields forever, or until the next orogeny #MinCup25

When does biology become geology? This is a fun paper for us (although I, myself, was just one more member of Band-Aid for this particular paper), and hopefully it helps clarify a lot of things that we sort of already knew but never really formally addressed. www.sciencedirect.com/science/arti...

yeah @geosociety.bsky.social I don't think I'm going to be attending GSA annual meeting this year

Drum roll for our next Tectonic Tuesday taking a look at a past event!! #Museum #tectonic #geophysics #VirginiaTech #Earth #mtsainthelens #VTGeosciences #tuesday

A fossil from about 66 million years ago reveals a species of dinosaur that is new to science, with claws that would have ripped through its prey's flesh

a warm welcome to joaquinraptor casali, a megaraptorid from maastrichtian patagonia 🦖 several features of the animal's anatomy suggest that megaraptorans retained robust arms and gracile skulls even at large body sizes, contrasting other massive theropods (art by andrew mcafee)

Welcome back to #trilobitetuesday Here is another specimen of the trilobite Elrathia antiqauta. This comes from the Middle Cambrian (Drumian) Conasauga Formation in Floyd Co, Georgia.

For the @nytimes.com, I wrote about Joaquinraptor, a new species from a very cool family of dinosaurs: long-armed, hook clawed (possible) tyrannosaur relatives from South America

A fossil from about 108 million years ago reveals an early member of the pachycephalosaurs, a group of dinosaurs with bizarre protrusions on their skulls that may have been used in combat

🌊 This week in our #AGU25 #CatchmentHydrology Early Career series, we highlight: “Resilient Infrastructure & Disaster Response Center” by Abdul Mobin et al. (2025).

Geophysicists have a suite of tools that help us "see" underground, like magnetotellurics. We can use these tools to locate critical energy sources deep underground and keep those systems safe to protect the planet while we transition to smarter solutions.

The Fall/Autumnal Equinox is TODAY at 2:19 PM EDT. That's the time at which our Sun is directly over the Earth's equator, signaling the start of Northern Hemisphere astronomical fall. The Earth’s northern hemisphere will continue to tilt further from the sun through the Winter Solstice on Dec 21.

Carbon comprising about 2.4 % of Earth’s inner core reduces the needed super‑cooling to roughly 420 °C, fitting seismic data that shows the core is ~10 % less dense than pure iron. https://getnews.me/scientists-reveal-carbons-role-in-earths-inner-core-composition/ #earthcore #geophysics #carbon

"The idea was taken up to explain the Laramide orogeny, as the flat slab subduction zones on the Andean margin are associated with more inboard surface deformation and magmatic gaps.[2]" 2 is a reference to Eugene Humpherys' 2003 paper and not Bill Dickinson & Walter Snyder's 1978 paper.

When you see the dramatic impact that a 1° change in the dip of the strata has on fluid flow in porous media, we field geologists might need to rethink our "+-5° is totally fine" when measuring strata dip angle. Thanks Thomas Poulet for the collaboration! doi.org/10.1130/G538...

⚒️ 🧪 Another big addition to the remarkable M8.8 earthquake sequence offshore Kamchatka: a M7.8 - the biggest aftershock so far. With foreshocks, aftershocks, aftershocks of foreshocks, and foreshocks of aftershocks, it's hard to keep these earthquakes straight! Read more about what's going on:

After having a great geo call with @earthjay.bsky.social yesterday, I am inspired to give this platform a go again! So here is my latest writing. Over the last few years I have been doing the classic newspaper column writing scicomm style. www.teawamutunews.nz/2025/09/pani...

I'm giving social media a go after a hiatus, so hi! I'm a Kiwi volcanologist working on Ngāuruhoe (Mt Doom) in NZ, the 2021 La Palma/Tajogaite eruption impacts, seafloor geologic hazards, & collaborate w. @geotenerife.bsky.social. More on my work here: janinekrippner.weebly.com Nice to meet you❤️🌋

Most people don't get it -- but this study nature.com/articles/s43... is co cool! Usually we think about the sequence stratigraphy as uniformitarian discipline/process/structure. But what if the evolutionary events, such as dinosaur extinction changed how stata look!? 🧪 ⚒️ #Paleobio #Geology 1/2

Happy #FossilFriday! Here's a little goober I haven't shared here yet: a Tianyulong jumping of a broken branch of Yimaia capituliformis (a relative of ginkgo). This is based on an unpublished specimen which did the rounds online a few years ago. #paleoart #paleobotany #paleontology #dinosaur

happy #fossilfriday! this is estemmenosuchus, a dinocephalian from mid-permian russia. due to its barrel-shaped body and dentition strongly resembling hippos, estemmenosuchus is theorised to have had a similarly amphibious lifestyle (art by philip edwin)

For #FossilFriday, one of the oldest known animal trace fossils interpreted from the geologic record (~565 million years old) preserved as a tiny trail on a bedding plane at Mistaken Point, NewFoundland (Canada), investigated during a 2012 visit by our hero, Paleontologist Barbie. 🧪🐾🪨⚒️

It's always fun when you can put out some new skulls in the exhibit hall! Taxa were chosen based on materials collected in western Colorado, housed at Museums of Western Colorado and BYU. Skulls were fabricated by Gaston Design Inc and Triebold Paleontology Inc.

For #FossilFriday a cast of Archaeopteryx siemensii the ‘Berlin specimen’ with its plumage restored by the prolific and fabulous sculptor Karen Fawcett.

#FossilFriday: a glacial erratic cobble of stromatolite, a fine algal carbonate rock, found at Cape Flinders, Kiillinnguyaq (Kent Peninsula), Nunavut, Canada, its source and age (probably Proterozoic?) unknown.

Fossil Friday flashback to Lyme Regis 2024 and one of the displays I’m most proud of, homaging Mary Anning, Walking With Dinosaurs, the incredible @emilyhiggs-art.bsky.social and also err Transformers… Really delighted how this came out and it was donated to the brilliant Lyme Regis museum 🏴‍☠️🖤🦖

Real skull of Sue the T. rex!! Did you know the one on the full display is a cast that removed the distortion due to crushing that we see here. #FossilFriday ⚒️🧪🦖

Quick video about the M7.8 earthquake off the coast of Russia, including an animation from @earthscope.org showing the seismic waves detected by seismic stations across North America. 🧪

I found a phrase that is resonating with my Intro Geosci and lab students this semester: It’s not about “right answers” in our labs, it’s about “reasonable answers” based on evidence. They’re taking a lot more chances and seem to be even more engaged than usual.
