I get that the news cycle is packed right now, but I just heard from a colleague at the Smithsonian that this is fully a GIANT SQUID BEING EATEN BY A SPERM WHALE and it’s possibly the first ever confirmed video according to a friend at NOAA 10 YEAR OLD ME IS LOSING HER MIND (a thread 🧵)

Der gemeinsame Sketch von John Oliver und Bernd das Brot feat. Void ist jetzt offiziell auf dem YT-Kanal von Last Week Tonight zu sehen. Am krassesten ist für mich, dass da tatsächlich auch Gags zu hören und zu sehen sind, die ich reindrömmeln durfte. Danke, Bernd. 🙂 youtube.com/shorts/k315N...

Excited to share my new open-access paper looking at magma storage depths for these beautiful xenoliths from Mauna Loa Volcano. doi.org/10.1007/s004... 🧵below, TLDR - previous suggestions of ~20 km deep Opx crystallization are inconstant with fluid inclusion depths and thermodynamic modelling.

kyanite X taenite. deep in the earth versus out of this world. I'm voting kyanite. go earth! #MinCup25 #minerals #sciart

🌋 New paper led by Emma Horn & the CAVES Project! We’ve characterised the glass geochemistry of 15 major Azores eruptions (~100 ka). This dataset provides fingerprints to trace Azores tephra across Europe, Africa & beyond. 🔎 🔗 doi.org/10.1016/j.jv... #Azores #Tephra #CAVESProject

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❤️🌋

#MinCup25 Round 2 Match 2: It's all about how minerals interact with humans as dramatic #stibnite faces off against futuristic #perovskite. Vote: www.mineralcup.org/2025/vote/r2... Results: www.mineralcup.org/2025/results...

Gestern ist die #Geo4Göttingen gestartet! Auch DVGeo-Geschäftsführerin Tamara Fahry-Seelig und Präsident Prof. Frank Schilling sind vor Ort und freuen sich auf den Austausch am DVGeo-Stand mit allen Teilnehmenden. 🌍🤝 #Geowissenschaften #Konferenz #DVGeo #Networking

The first ornithomimosaur remains from Germany DENIS THEDA, DARIUS NAU, RENÉ DEDERICHS, and ACHIM H. SCHWERMANN It's open access! www.app.pan.pl/article/item...

With great pleasure I would like to introduce you to the first ornithomimosaur from Germany! The fossils of this charming bugger are from Balve, a locality that preserves early Cretaceous fossils in a Devonian reef that had karstified already back then, giving us: cave dinosaurs

Prehistoric Planet Ice Age out later this year... such a thrill to put this series together, oh my goodness are you in for a treat :) Hopefully news on events and publicity coming soon! Sloths, cats, rhinos, glyptodonts AND SOOOO MUCH MORE!!

Job Alert! The University of Tübingen is hiring a FULL PROFESSOR (W3) in FUNCTIONAL ECOLOGY! Come and join our institute, and maybe our new excellence clusters @terra-cluster.org and @greenrobust.de. @gfoesoc.bsky.social @britishecologicalsociety.org @ecologicalsociety.bsky.social Please repost!

remove one part CuCO3 from Azurite and it turns green. So colorwise it's clearly an upgrade! #MinCup2025 #Azurite

Colored portrait sketch of Troodon formosus, a troodontid theropod from the Late Cretaceous of USA and Canada. It was initially described by tooth as a lizard and then referred to pachycephalosaurids. Later it became clear that Troodon was a bird-like theropod. #paleoart #dinosaur

#azurite for that lovely blue, which was pretty hard to capture, evidently. Left from Tsumeb, right from Clara Mine in southern Germany.

And the #TeamCalcite curse continuous...

Look at this #calcite crystal and its super strong birefringence, yielding two distinct optical paths! And yes, that's Captain Haddock, a subtle reference to the strong polarization effects in calcite sunstones, likely used as navigational aid by seafarers in the Viking Age. #MinCup25 #teamcalcite

Ok, seems like I need to utilize the nuclear option: all my past collection of posts about #Team Calcite:

This cabinet solely wins #MinCup25 for Calcite. ⚒️ #Geology

Perovskite isn't futuristic anything. Perovskite the mineral has no connection to solar panels or the deep mantle. The word "perovskite" in solar discussion has to do with a similar crystal shape of something that is compositionally *completely* different. Calcite, however, is actually calcite.

I’m voting Haüyne! Born of volcanoes, no active mines, mostly amateur collectors find the blue beauty. It’s the people’s gem…plus the Umlaut. #mincup25

It's #Haüyne for me today! The largest and most precious Haüynes have been found in the Eifel region of Germany (the largest one found so far has 3.2 cm in diameter) and I even found one myself two years ago 💎. ⚒️ #MinCup25

Vote Haüyne, vote for its blueauty, vote for the only Umlaut in the cup, vote for its sulfur content, vote for the largest eruption on continental europe in the past 15.000 years this Eifel specimen originated from. #MinCup2025 #TeamHaüyne

I’m currently fundraising to purchase two excavators and a transport truck to deliver them. This equipment takes time to deliver and repair, with a goal of completing the transfer within two months after the fundraiser is fully funded. The machines will support the 72nd Brigade of the UAF.

1/ Last month, I launched a fundraiser to provide engineering equipment for Ukraine, but due to low donations, I had to pause and reassess. Today, I’m relaunching the fundraiser and want to share an example of the impact of the machines we provide. Share and donate. 🔗 www.paypal.com/donate?campa...

Not at all an ominous mirroring of this first round how in the geologic collection of Göttingen this Pectolite sits right above Chrysotile... 👀 #MinCup2025

Keep on being amazed by this Seastar S30. Some images from tonight. If you're into this sort of thing, we live with a Bortle ~5.7 sky here in Granville.

How does lava sound when it comes to the surface of the Earth? Listen to a lava flow oozing out of its effusive vent high on the southwestern side of #Etna, 28 August 2025. That day no visits by tourists were allowed on the site, which permitted this (relatively) clean recording

I'm a big calcite supporter since 2017. We got close and far over these years so this will be another chance. But calling it now, Paddlewheelite will come to at least the (semi-)finals simply due to its funky name. Still a carbonate so I wouldn't be too upset.

Behold, the #MinCup35 bracket! Use it to follow along, plan campaigns to support your favs, or make predictions on how voting will shake out. We start at the top left on September 1st, then alternate left and right as we work our way down.

Rock Looked Way Cooler Wet

The Southeast Crater - youngest and most active of the four summit craters of #Etna - producing Strombolian explosions and a lava flow on the evening of 24 August 2025. The current summit eruption started on 14 August. Photo taken from Nicolosi on Etna's south flank.

Heute ist der 34. Unabhängigkeitstag der Ukraine. Im Internet nicht zu übersehen. Der wichtigste Nationalfeiertag – und er bewegt das Land. Getötete Soldaten, gefangene Zivilistinnen in den russisch besetzten Gebieten: Die Ukraine zahlt einen hohen Preis für ihre Unabhängigkeit.

Cool #paleoart : Sauropoda by @emilyhiggs-art.bsky.social. Not in her trademark folded style, but v fine & v Emily nonetheless! Another one of the prints I bought at @dinoconuk.bsky.social (technically @tpbunny.bsky.social procured this for me).

233 of #365Minerals 🧪⚒️ Pyrope: - A magnesium-rich garnet group mineral - Forms in ultramafic rocks (e.g. peridotite from the mantle) - Its name comes from the Greek word "pyropos" (fiery-eyed) because of its red colour #minerals

Alle Menschen haben das Recht auf freie Meinungsäußerung. Aber manche verwechseln das mit dem Recht, dass ihnen dabei auch zugehört wird. Oder mit dem Recht, danach von Widerspruch verschont zu werden. Und dieses Recht hat niemand.

We are happy to announce that hiring has begun for the Cluster Coordination Office @unituebingen.bsky.social! Would you like to join the team that supports research at the intersection of the geosphere and biosphere? Do you know someone who might be interested? Please share the post!

Everyone wants the war to end, negotiations to succeed, peace to come. The reality: it won’t happen soon. That’s why I’m fundraising for a new batch of engineering equipment—excavators and trucks with cranes. donation link: www.paypal.com/donate?campa... please read the tread below ⤵️

When picking minerals for the bracket, we’re heavily influenced by: 1. a clearly-enthusiastic advocate that will campaign for it 2. neat campaign angles (facts, stories, history) 3. variety compared to the rest of the bracket & past competitions
