1/3 Well this is a first (for me): Native #copper replaces ancient cross-bedded sedimentary rock perfectly preserving the original cross-bedding. Copper does amazing stuff in Michigan. 🤯 More below!

Water Flea, possibly Chydorus (?) Very silly looking little guy, in my opinion.

Excuse me what!?

Nosso bebê nasceu 🥹 Uma nova espécie de pterossauro do Araripe, encontrada dentro de um vômito fossilizado de dinossauro 🤍. A natureza é linda! Kkk Seja bem-vindo, Bakiribu waridza! Acesse o artigo: www.nature.com/articles/s41...

Probably got told the chance of it obtaining a permanent academic position. *limulus dies*

‼️New PhD project in Edinburgh: "Animals, traits, and oxygen in the Ediacaran Nama Group, Namibia". Supervised by Rachel Wood (Amelia Penny and I co-supervising) — big UK+Namibian team — help us understand early animal evolution! Apply by Dec 14th #paleontology e5-dtp.ed.ac.uk/project?item...

Here are some fossil pleurotomariids, which have lived in Earth’s oceans for over 450 million years.This is a kind of snail you won’t find in your garden or on a seashore. You’d have to dive 400 meters to see a living one.If you could beachcomb in the Jurassic, you’d probably find one on the coast🐚

#Copper is the oldest metal worked by humans, & is 100% recyclable. Nearly 80% of all copper ever mined is still in use today. Historically significant examples of its use include the Statue of Liberty, which is made of copper. Vote info 👇🏼 #OreCup ⚒️ sci-fi 🧪 Geosciences #WomenInSTEM geology 🍎 🔭🪐

Lots of hard, shitty lessons being learned from this presidency. And one of the many I hope you're learning is, white supremacy is incompatible with reality, and cannot exist without historical revisionism.

I didn't study geology because I wanted to do maths or computer programming. They do not interest me. I wanted to learn about rocks etc. I also have severe dyslexia and dyscalculia. I literally cannot *do* maths beyond a basic level. Should that preclude people like me from geo/earth sciences.

Those Laowa lenses are great.

Fellow seismologists, we're going to get a lot of mileage out of the latest @xkcd.com

Peacock ore Bornite is very pretty but only gets art/physics points as a source of copper & I’d rather vote for copper itself. So I am going to vote Molybdenite for physics reasons (source of Re for geochronology, Mo used as a catalyst, battery electrodes, alloys of iron & semiconductors). #OreCup

Bornite is great, but #molybdenite is not copper! I kid (kind of)! A soft, silver, greasy, hexagonal mineral that can look like JiffyPop, foil-wrapped leftovers, or metallic graphite. It can handle high-stress/high-temps, & it's anti-corrosive. Those seem like good qualities here & now! #OreCup

A friend of a friend is at risk of losing her home and sadly rehoming her beloved dog due to falling on hard times. Regina was let go recently and hasn’t found stable work yet, and she's lost her mom and other dog recently. if you can help them stay together, here's a link to their gofundme:

Some of you may know #philsci #philbio Subrena Smith, Prof of #philosophy at UNH. Her family in Jamaica lives in one of parishes hardest hit by Hurricane Melissa: Westmoreland. She & David are raising funds to support them w/ generators, supplies, truck water in to them, etc. Please donate if can!

Vote #molybdenite! It’s a pretty blue silver color, it’s found in porphyry deposits (my favorite), it’s fun to say and spell, and there is a famous molybdenum mine in Colorado named Climax with it’s hilariously named “Glory Hole” created by underground block cave mining. (Be careful googling that)

The eye of the teeny tiny ciliate storm. A rare look down the opening of a tintinnina lorica. #marineplankton 🦑

@nhmbryozoa.bsky.social saw these Fenestrate #bryozoa (?) In #Devonian limestone from Belgium. They have these feathery extensions, like in the 2nd pic. Have you seen anything like this previously? #geology #paleontology ⚒️ 🧪

People often wonder why I like metal so much. What a great story.

I found a new women in engineering podcast today whilst making a speaker shortlist for a future @earthsciencewomen.bsky.social event! Passing on to the world of Bluesky 😀 open.spotify.com/show/7D5CxK7... [event release coming in January 2026]

Day 188 of photoshopping @lastweektonight.com's #JohnOliver with fossils in the hopes that he saves the Paleontological Research Institution John(H. sapiens) with a Leptopecten gilbertharrisi, named for PRIs founder, who didn't trust Cornell to value his science/collections 👀 #SavePRI #Cornell ⚒️🦑🧪

It’s been a crazy family health crisis kind of month, but I finally made it back into the studio to finish up this 24x36” acrylic on canvas painting titled ‘Huggies and Snackies’. A beautiful stalked carnivorous sponge is joined by pink brittle stars and a golden crinoid. Cuties 😍 #deepsea 🐡🦑 #art

Hey hey #FossilFriday . A beautiful Discoscaphites conradi from the Fox Hills Formation (Upper Cretaceous) of South Dakota. Not pictured: on the opposite side is nice partial Sphenodiscus. Personal collection, my own photo. #ammonite #fossil #geology #paleontology #cretaceous

When people celebrate the individual genius of folks in science, they should also mourn the collective loss of genius of folks who were actively discouraged or disadvantaged from a career in science because of the same person(s)

We didn’t always recognize #Molybdenite or know how to use Mo until the late 19th Century. Rh wasn’t discovered until 1908. After early experiments during WWI, automobile and aviation industries found uses for both elements in high-performance alloys. Then catalysts and medical uses. #OreCup25 ⚒️ 🧪

#Bornite still has my vote with those peacock colors. Professional science nerd or not,sometimes my magpie brain takes over. #OreCup

#FossilFriday Here are 3 beautiful Pentremites sp. Blastoids I collected from the Upper Mississippian (Lower Carboniferous, Serpukhovian) Lower Bangor Limestone in Russellville, Alabama.

This Australian Fur Seal is having a nice little snooze. I've watched them do this in a swell, off a rocky shore, by anchoring themselves in floating kelp. The world's biggest fur seal, they mostly eat squid, octopus, fish and lobsters & can dive to 200m. #WildOz #seals #AustralianWildlife

In 2010, a scientist argued that 2.1 billion-year-old African specimens showed complex life appearing 500 million years ahead of schedule. His critics say they are — literally — fool's gold. At stake? The question of when and how complex life arose at all. My cover story (!) for @sciam.bsky.social!

Permian (~260 million year old) fossil wood of Glossopteris and its delicious scale bar to celebrate #FossilFriday! #paleobotany 🍃⛏️🍫

#FossilFriday _Paramatonia rafaherbstiana_, just published fern from the Lower Cretaceous of Patagonia

Late #FossilFriday this tiny bebe frond on a siltstone bedding plane from an undisclosed UK location of suspected #Ediacaran age. Lots of interesting frond-like structures on these samples. #Geology #Paleontology ⚒️ 🧪

#fossilfriday An early fossil dolphin earbone (tympanic bulla) with the middle ear sinus just completely filled with little fecal pellets, revealed by acid preparation. From the Oligocene (26 myo) Pysht Formation of Washington. More on my blog: coastalpaleo.blogspot.com/2025/11/acid...

Happy birthday to #physicist Lise Meitner (1878-1968) who explained #nuclear #fission. 🧪🐡👩🏼‍🔬#histsci She worked with chemists Hahn & Straßmann in 30s Berlin, investigating whether there were any stable elements beyond uranium. They discovered bombarding nucleus of U-235 with neutrons actually 🧵

For #FossilFriday, limestone steps filled with lovely, well-expressed & abundant invertebrate burrows, rendering fossil art in front of the @philamuseum.bsky.social (near the Rocky statue), seen there in March 2026; size 8 1/2 mens shoe for scale.

A seed fern fossil (Alethopteris?) from the Upper Carboniferous in Gelsenkirchen, Germany. #FossilFriday #Fossils 🧪 ⚒️

Watson’s death is a fantastic reminder that you can be intelligent without being a good person.

Just a reminder, that possibly the oldest piece of palaeoart dates to the Neolithic. The petroglyphs of horned characters with trumpets, recorded on the same rock as a ornithischian footprints (Zagaje Formation) in Poland, might be an early reconstruction of the Jurassic tracemaker.
