A group of Dorygnathus use a Seirocrinus raft as a hunting ground for fish, when a big Eurhinosaurus suddenly breaches the surface.

This scene takes place in Germany during the Early Jurassic, around 180 million years ago.

We have truly not yet figured out how to cope with a person or institution that is "aware" of climate change, "accepts the science", but then decides to continue actively worsening it anyway

We don't even have a word or a phrase for this!

Mark Carney’s climate inaction is at odds with his awareness of climate change’s existential threat
Climate action no longer seems to be a priority for Prime Minister Mark Carney, despite his previous activism. This is bad news for Canadians and the climate.

#ZAVACEPHALE IS FINALLY OUT! 🥳 Our first definitive Early Cretaceous pachycephalosaur! (~15 my older than the previous oldest pachycephalosaurs) And the first hand material for the clade! I can't tell y'all how much of a pleasure it was to review this paper! ☺️

Would you believe that we don't have an evolutionary tree for the biggest group of fossil jawless fish? UNTIL NOW THAT IS!
Our new paper "A Phylogeny for Heterostraci" 10+ years in development, 100+ taxa, is finally out (thread)

WTF? I was quoted in this story but I have never spoken to the reporter nor would I have said those things. Is everything just generated by LLMs these days?

cosmosmagazine.com/earth/oceans...
To whom it may concern, and it should concern the editor: I was quoted in your publication: https://cosmosmagazine.com/earth/oceans/can-we-engineer-our-way-out-of-ocean-acidification/ Still, others aren't convinced that good intentions are enough. Dr. David Ho, Professor of Oceanography at University of Hawaii at Manoa, a cofounder and the Chief Science Officer of |C|Worthy, a non-profit that works on verifying ocean-based carbon dioxide removal, believes carbon removal efforts like ocean alkalinity enhancement shouldn't be left solely in the hands of private companies. "They have no way to prove that what they're doing is effective - that's a big problem," Dr Ho said. The crux of the dilemma, he explains, is that we are fighting a planetary-scale problem, but are doing it with tools that are still being built and tested. Geoengineering is not inherently good or bad, but it is inherently powerful. And power, especially when exercised in ecosystems as complex and fragile as the ocean, must be handled with caution. However, I have never spoken to your reporter, nor would I have said those things. I would like you to remove my quote from your story, and issue a public correction and apology. Furthermore, you should look into whether the other parts of the article are also factually correct. Thanks. d.

Qilin tungurensis (formally Palaeotragus tungurensis) have a new genus name now!
Mainly based on the holotype and paratype AMNH 26582/26583, the part of horn core based on the refered IVPP V33851.

Article 1, Section 9 & 10 have been removed from the official Govt website on the US Constitution. Among numerous points:
•Section 9 forbids suspending The Privilege of the Writ of Habeas Corpus
•Section 10 forbids ex post facto laws

This better be a joke. Ignoring these is full blow dictatorship

You'd think "pterosaurs" & "kink-shaming" are two things that couldn't go hand-in-hand, and yet, a homoerotic scandal between two intellectual equals led to the discovery of the first pterosaur. Buckle in for some Crazy Rich Prussians & their unlikely connection to the discovery of pterosaurs 🧵

“We are not giving Google special access to your iNat data, and we have no obligation to use Google's infrastructure…If the demo… is not helpful, compromises data quality, has outsized environmental impacts, or is … too flawed, we will not keep it.”
We recognize that this announcement has caused a lot of upset and confusion among people who care deeply about iNaturalist. In the hundreds of comments, we hear that many people feel betrayed, disrespected, and without agency. We sincerely apologize. With respect for the ethical and environmental concerns raised, we'd like to offer more clarity about our plans with this grant and program. We know that trust is not easily rebuilt, but we'd like to try. First, to clarify some things we did not clearly communicate: 1. We are not replacing or changing the current human-curated system of identifications. Many of you have rightly pointed out that this is at the heart of iNat, and we wouldn't dream of doing away with it. Anything we explore with Al would only be meant to enhance the experience of some users: by, for example, providing an interesting tip about identifying the species, suggesting that the photographer try to capture a particular aspect of the plant or animal that might aid a human identifier, or explaining the computer vision's logic for the identification it's suggested. 2. We are not giving Google special access to your iNat data, and we have no obligation to use Google's infrastructure as part of this grant. Google is providing funding and advice on how to potentially leverage Al. 3. Naturalist has successfully incorporated machine learning and computer vision (kinds of Al) since 2017, with a very small footprint (primarily three machines running in spaces we control). We understand that new technologies can have much larger environmental impacts, and we aim to quantify the environmental footprint of Naturalist's infrastructure for 2025 and beyond. 4. This grant funds our team exploring new ways to surface and organize helpful identification comments - and if the demo we create is not helpful, compromises data quality, has outsized environmental impacts, or is overall too flawed, we will not keep it. This project is just getting off the ground, and we … Done • inaturalist.org AA The Naturalist community has always been a core partner in informing the direction of the platform, and we appreciate and hear your feedback (including but not limited to): • We understand that you are concerned about inaccurate, out-of-context and/or hallucinated information being provided by a tool like this. We agree that any Al-provided information be clearly labeled as such and that there be a way to upvote/downvote or otherwise flag potentially misleading information, and we are excited to explore more ways for how this may happen. • We hear that people would like to be able to understand and control how their data is used on and beyond iNaturalist. On iNaturalist, you own the copyright to your data, and iNaturalist Terms of Use prohibit the use of data for commercial Al training. Whether commercial Al companies are beholden to copyright law or terms of use or can argue "fair use" of publicly accessible data is being worked out in the courts and is something we are paying attention to. • Most importantly, the community will be involved in the creation of this and any major new features. We will not be implementing any new changes to what you see on iNaturalist right now without involving the community. Our plan is to have an initial demo available for select user testing by the end of 2025. If you have more feedback, ideas, concerns, or questions you'd be willing to share, please use this form so we can more easily keep track of them. Additionally, if you would like to attend a virtual Q&A session to have some of this discussion in real time, please let us know in this form (more details to be determined). Again, the project funded by this grant is just getting started. We will proceed carefully and respectfully, and we're immensely grateful for this incredible and engaged community.

OK, this is wild.

In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.

It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.

What the HELL?

Well the award for most cowardly, boot-lickingest academic society has squarely gone to the American Society of Microbiology, who has taken down features of various non-white scientists. Absolutely pathetic behavior. Those articles are now coming up as “under review”. Truly sickening cowardice here.

Marc Andreessen is a billionaire, @nytimes.com. Do you think that might disqualify him from “normie” anything?

Cool bootlicking clickbait, though.
Listen to 'Matter of Opinion' Marc Andreessen was a "normie Democrat," he says, until Democrats drove him - and much of Silicon Valley - into President-elect Trump's arms.

UALVP 45014, a putative Ischnacanthus gracilis specimen from the MOTH locality in NWT, Canada. Several exquisitely-preserved MOTH specimens unexpectedly turned up during our big move last year and were promptly returned to the fossil fish collection (after I snapped a few shots).
