In South Africa, paleontology has been dominated by white people. Lazarus Kgasi is changing that dynamic — and coloring in the picture of the world our distant ancestors once inhabited. n.pr/49WF6w1

Scientists just found that a curious group of plankton began to flourish rapidly after the dino-killing asteroid—a key sign life was on the mend. They made their discovery by measuring the slow accumulation of space dust after the impact. #Paleontology #PlankticForams New for @science.org 🧪🏺

VOLUNTEER ON A DINOSAUR DIG: We run one of the only free dinosaur digs in the USA. We work public land and the fossils go in our public museum, forever. It's hard work, but we find some cool things. If this sounds like you, we're taking applications. Link in comms. #dinosaurs

A bittersweet article today as Gemma remembers a hidden gem in Emmen, a dinosaur museum that is no longer there.

Nerinea are an extinct type of fossil sea snails. They used to build huge banks in the Mesozoic, their distribution expanding and contracting latitudinally as the oceans and global climate shifted. 🧪⚒️ Link: pubs.geoscienceworld.org/sepm/palaios...

Dickinsonia, back when evolution was excited to make pancakes. Paleontologists are pretty sure Dickinsonia was an animal, a creature that lived in the sea around 550 million years ago. The flat, ripply organism adhered itself to the floor with mucus and grazed on mats of microbes. Slick. 🧪

(1) Another long 🧵 because @societyofvertpaleo.bsky.social finally put out a statement on Jack Horner's association with Jeffrey Epstein and this is about the most spineless pooh poohing of a serious safety and moral issue I have read. I guess studying vertebrates does not require a backbone...

Really SVP? You’re just going to ignore decades of sexual and academic misconduct, marrying a student AT one of your conferences, and every report I’ve filed (implying that’s what you do with reports) to defend famous Horner? You’d rather have pedophiles than students is your message?

I gotta say though... they've known about this person's behavior for *decades*. I first heard rumours of it on my first trip to the US in 2005! Why would they act now, rather than that time he married *his own undergrad?*

Is @societyofvertpaleo.bsky.social being serious here? No, the presence of a name on an email doesn't establish wrongdoing. But the *content* of those emails is what so many members, including myself, are outraged about. This response does nothing but further degrade my confidence in SVP leadership

It's extremely difficult to tell, but it appears that the location of the Rubaya mine collapse and landslide is 1.56728° S, 28.88571° E as seen in thiese @planet.com satellite images (landslide moves S to N). The entire region is pockmarked with mines, including on slopes (like this one was). 🧪⚒️

We are kicking off some new work in the Northern Cordilleran Volcanic Province this summer we hope! Exciting times, with Shaun leading the way. Some pics from 2021 when we collected the cores presented in the paper 🧪🌋 #fieldwork #geology #tephra

In 2003, I published a paper on an incomplete large theropod tibia recovered from the Lower Cretaceous Hastings Group (part of the Wealden). It likely belongs to a member of the Allosauridae + Carcharodontosauria clade within Allosauroidea rather than to a metriacanthosaurid... cont #dinosaurs

Welcome back to #TrilobiteTuesday! Here is the cephalon of the "lace collar" trilobite Cryptolithus tessellatus. This comes from the Upper Ordovician Kope Formation (Lower Cincinnatian Series) in Maysville, Kentucky. What you usually find are just pieces scattered throughout the limestones.

I’m putting my Rancho Gordo beans to work today in class. My paleoecology students are sampling and identifying “microfossils” (beans) from a time series and plotting relative abundance data. They have to grapple with how to handle data visualization, broken specimens, unknowns, lumping/splitting.

Just look at this beauty! This is autunite, a hydrated calcium uranyl phosphate #mineral (Ca(UO2)2(PO4)2·10H2O for you purists) under UV light. This sample is from Cornwall (UK), a secondary mineral from pegmatite-associated uranium. I had fun teaching our 3rd year Bristol geologists today! ☢️😁

I think what really works is touching soil, not grass.

Ophiolites play a significant role in our understanding of orogenic evolution. This study on the Ballantrae Complex in Scotland integrated geochronological and geochemical data to reconstruct the opening of the Iapetus ocean.

Recent assessments have found the last glacial maximum implies a climate sensitivity of 2.4C (1.4C to 5.0C): www.science.org/doi/... And the Pliocene implies a sensitivity of 3.1C (2.3C to 4.7C): www.pnas.org/doi/10.... Paleoclimate evidence generally provides the strongest constraint on high ECS.

One of the most surprising things I've learned from my research is that "how hot it's gotten so far" doesn't tell us much about "how hot it's going to get eventually". Long-ago, really weird climates can tell us a lot more about where we're headed.

2 new papers by Cooper, Armour & co use past climates, from the Last Glacial Maximum 21,000 yrs ago & the Pliocene 2.6-5.3 million yrs ago, to infer that the planet will warm about 3 degrees C for a doubling of CO2 as a best estimate for present day. doi.org/10.1126/scia... doi.org/10.1073/pnas...

Contact between garnet and clinopyroxene in retrogressed eclogite. Lots of pargasitic amphibole around

More than a century after the fossil mammal was named, this is still the best fossil we have of Andrewsarchus. Currently it seems the big beast was a hoofed mammal related to entelodonts, but we need more bones to work out how this Eocene creature fit into the mammal family tree. 🧪

To my great surprise, an article on a tiny (larval?) mysterious insect #fossil 🦖⚒️ from Permian of Germany, on which we were working since about Triassic, suddenly got published. Check out cute critter, its OA @cocomacro.bsky.social link.springer.com/article/10.1...
