Pleased to report that the Chinese edition of my book 'Life Sculpted' (2023, @uchicagopress.bsky.social) was published in December 2024 as 雕刻地球的生命 by Shanghai Scientific & Technological Education Publishing House. The cover image is beautiful, featuring a bioeroded clam shell as its main image. 🧪📚✍️

How do you select a name for a new dinosaur? Sneak peek on #FossilFriday of the next @thefossilfiles.bsky.social episode out on Tuesday with @tweetisaurus.bsky.social youtube.com/shorts/5Cbz9...

For #FossilFriday, meet Inoceramus : the largest bivalve to ever exist. This genus lived in the Cretaceous seas of North America and Europe. This one is 178 cm long. And look at these rings ! It must an amazing palaeoenvironmental recorder to work with 😍 #PaleoSky 🦑 🧪 ⚒️

A frond of Phlebopteris, a 230 million year old fern from the Late Triassic Chinle Formation, New Mexico/Arizona. #FossilFriday #FernFriday ⚒🌏🌱🧪🔬🌿

For #FossilFriday a chance to shake hands with the #IsleofWight dinosaur Mantellisaurus atherfieldensis.

102,000 hairdressers in England with 40,000 salons 27,000 GPs with 6200 Surgeries 31 million people visit GPs every month a similar number have haircuts You can see the problem @rthonwesstreeting.bsky.social judging by Wes’s trim he is going to the hair salon a lot more than his GP unlike many

300 million year old Neuropteris foliage, on display in Wollaton Hall, Nottingham's natural history museum. Specimen is about 20cm across, locality is Clay Cross, Derbyshire. #FossilFriday ⚒🌏🌱🧪🔬🌿

This is the only "complete" crinoid in my collection, from holdfast to crown. It's easy to see why they are sometimes called sea lilies, even though they are animals related to starfish and sand dollars. This is Abatocrinus gallatinensis from the Mississippian Lodgepole Fm of MT. #FossilFriday

This #FossilFriday we have wrapped up a wonderful field season in Newfoundland on #Ediacaran life - here are some tiny #Fractofusus for #FractofususFriday from Mistaken Point

For #FossilFiday a new paper on the size change of Hopolopteryx fish during the #Cretaceous with varying ocean temperature. The study was part of the @chalksea.bsky.social project & led by Masters student, Chloe Griffiths. Well done Chloe 👏 onlinelibrary.wiley.com/doi/10.1002/...

For #FossilFriday a posterior view of the braincase of the Early Cretaceous fish-eating spinosaurid dinosaur Baryonyx walkeri. In the collections of @nhm-london.bsky.social. First discovered in Barremian aged Smokejacks brick pit Surrey by collector William Walker in 1983. Time flies!

It's induction week at @bournemouthuni.bsky.social and there's nowhere better to take the new @buarchanth.bsky.social intake than the mighty Maiden Castle Love this place 😍 #IronAge #Hillfort #Dorset #Archaeology #HillfortsWednesday on a Thursday

This wax model of a human head from the 19th century shows the internal structure of the brain, complete with its protective covering, the meninges, the eye, cheek, neck and jaw. Wax models were used for teaching anatomy to medical students or as part of popular anatomy shows.

Similar cousins, and yet so different animals! See the skull of my new species Cariocecus bocagei -published this week- at the foot of the Iguanodon statue at @naturalsciences-be.bsky.social for #fossilfriday #dinosaur #paleontology

This week’s #FossilFriday features a very cool opalised dinosaur femur, belonging to an Early Cretaceous Australian ornithopod (Click the image to see it in full detail) #PaleoSky ⚒️🦕

Prepping for the start of this year's teaching this #FossilFriday, starting with a story about Ginkgo leaves which fell in an Autumn 160 million years ago, and how the microscopic details of those fossil leaves can tell us about climate change. ⚒🌏🌱🧪🔬🌲💚

#FossilFriday A succession (anagenetic?) of Two Medicine Formation centrosaurines from @museumoftherockies.bsky.social: Stellasaurus, Einiosaurus, Achelousaurus

#FossilFriday Choose your favourite fossil ‘lollipop’ from these specimens of the Cretaceous stalked sponge Siphonia tulipa. Another unused image taken for ‘Fossils. The Essential Guide’.

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

A reminder about the #SVP2025 workshop "Palaeoart Past and Present: the view from the UK" for those last-minute early-bird [=cheap] conference registrants! It's shaping up to be a great one-day pre-conference event: please come along if you're a #paleoart fan attending SVP!

Here's a dinosaur trace for this week's #FossilFriday — a footprint of a large 'carnosaur' (likely a carcharodontosaur) at the Mill Canyon Dinosaur Track Site outside of Moab, Utah. This is easily one of the most impressive dinosaur track sites in the world, and it honestly needs more protection

Species interaction over millions of years. Limpets sheltering in a dinosaur footprint seen at the impressive Triassic track site at the Bendricks, Barri, Cymru. #FossilFriday

Telegraph headline feels inflammatory - there's no tearing, just careful removal of a flag from a grade 1 listed historic monument that belongs to the nation.

For #FossilFriday a memory from 9 years ago of my first sight of the @bobnichollsart.bsky.social beautiful and accurate model of an Early Cretaceous parrot faced dinosaur called Psittacosaurus.

Well Fossil Files fans, this week you have a special bonus episode our new dinosaur #Spicomellus the spikey ankylosaur. In this episode, I tell Rob all about the back story: how we found it, excavated it and studied it. And I throw some shade on fossil smugglers. fossils.libsyn.com/the-spicomel...

My God. The Supreme Court has legalized racial profiling. I have darker skin than the average American. It's insane that if I'm at the supermarket or a ballgame or whatever, a masked ICE agent can now simply look at me, detain me, and demand to see proof of my citizenship. Maybe you too?

#FossilFriday Hedwig Kniker, Esther Applin & Alva Ellisor were the first to identify the importance of Foraminifera microfossils in correlating & interpreting stratigraphies, in 1921 #WomenInSTEM ⚒️🧪🔬 paleonerdish.wordpress.com/2022/06/29/f...

Well done, Sussex Bylines. Excellent analysis and the issue is urgent.

Heads up for #SVP2025 attendees: I'm running a day-long workshop about UK #paleoart on Nov 11th (the day before the meeting). Essentially a mini-conference, it's a day of talks on UK palaeoart history, conservation and current projects, as well as... 1/3

Weekend reflection on Spicomellus & difficulty funding fieldwork. We were lucky to get some funds from NHM & UoB but major funders turned us down. Only generous support from BILNAS made this project possible. Funding fieldwork is often considered ‘risky’ yet our results were published in Nature.

Hey MSM, ask RFK Jr to define 'inflammation'. Ask him to define 'mitochondria'. Ask him how, specifically, that he can tell how children have 'mitochondrial challenges'. Ask him what, specifically, about children's faces and body movement indicates inflammation. He won't know. He's making shit up.

We're talking all about DEINONYCHUS on the 60th anniversary of its discovery! Join us to learn about how this dinosaur helped spark the 'Dinosaur Renaissance,' changing the way scientists (and the public!) think about dinosaurs forevermore Join us now @ twitch.tv/paleontologizing

Out today in Nature is the most exciting dinosaur paper I've ever been involved in - led by @tweetisaurus.bsky.social we describe a partial skeleton of the UTTERLY BIZARRE Spicomellus from the Middle Jurassic of Morocco, the oldest known ankylosaur. (1/x) www.nature.com/articles/s41...

Here's the paper: www.nature.com/articles/s41...

Hi all, me, @richardjbutler.bsky.social and the amazing UK-US-Moroccan team are delighted to announce that.. we have a new specimen of Spicomellus AND IT'S WAY WEIRDER AND WAY COOLER THAN WE EVER IMAGINED!!

With the US becoming an uncomfortable home for academic researchers, we should be welcoming them not pricing them out our coming here.
