A doubly old 'Christmas tree' this #FossilFriday! This was taken on Dec. 23 2010 during my 1st trip to Antarctica & shows a large fossil tree from the Triassic, 240 million years ago. The locality is high in the Transantarctic Mountains, above the Antarctic icesheet 🌿⛏️🏔️ Happy holidays! #paleobotany

Make a bond movie casual Dr maybe

Super cute snail

This time of year has not been great for me or felt right for more than half my life now. This lovely wee thread reminds me of the times it was good.

⭐️ Recap of 2025 - Our Biggest Stories of the Year ⭐️ 👉 Throughout the year we've been installing new interpretation and information points across Charnwood Forest - sharing the Geopark's amazing heritage. 🌐 Read more about our work in Thurcaston: www.charnwoodforest.org/thurcastons-...

#FossilFriday Fine specimen of the problematical fossil Dickinsonia costata from the Ediacaran. On display at the South Australia Museum, Adelaide.

Looking forward to getting back here when I finally escape Belgium.

‘‘Tis the season. Tra-la-la-lobe-ite, painted in ArtRage, like 17 years ago. Merry Merry, everyone. 🐡🎨🧪

On the 12th day of fossils, my true love gave to me... 12 Crawfordsville echinoderms! Crawfordsville, Indiana is home to the Mississippian aged Edwardsville formation, famous for an amazing diversity and density of crinoids. 95+ different crinoids are found here. 1/x #12DaysofFossils

Happy #InverteFest to everyone who celebrates. Post your invertebrate art.

Random reminder that I've written a couple of nonfiction popular science books that I think are fun! You can find them at your favorite bookstore. Or Amazon.

We have 1 slot left for this season's art book! First come, first serve. If we overflow I'll move the extra submissions for the April edition.

Welcome, former Twitter artists! From paleoart to fine art, comics to medical illustration, bioart to space imagery, explore the rich SciArt ecosystem on Bluesky with the SciArt Starter Pack. 150 artists, plus the entire popular SciArt Feed 🐡. And no gen AI or NFTs.

Time to art some bugs! #InverteFest

🚨 Pre-announcement! 🚨 We’re hiring for 2 x two-year, full-time roles to join me and the wider @palaeoverse.bsky.social team @es-ucl.bsky.social. - Research Software Engineer (REF: B04-06999): lnkd.in/eNRBiPnP - Community Engagement Coordinator (REF: B04-06998): lnkd.in/ejUACCzn

Same. "Listen kids. I don't know what a labooboo is. But do you wanna see some weird 3 billion year old fossils I found the other day?"

It's that time again! Merry Christmas everybody!

Random, super interesting piece of rock at Royal Domain of Drottningholm, outside of Stockholm. #Geology ⛏️

DAY 202 SPECIES 202 - Methanococcus vannielii STAGE: Archaea MEDIUM: Arches Paper. Chromatek, Watercolor. Sakura pen M. vannielii is a motile, gram-negative, coccus-shaped archaeon that was isolated from marine mud. It lacks a cell wall making it fragile. #sciart #watercolor #archaea #art #paint

Phidoloporid bryozoans, like this colony picked from a crab pot at Apollo Bay, Victoria, Australia last month, are often confusingly known as 'lace corals'.

Silent Hill creatures spotted at Crystal Palace.

Mid week #FossilFriday work in progress on an interpretive sketch of some of the enigmatic Proterozoic #fossils I've been working on for several years. These examples are just over a billion years old. #Geology #Paleontology

Harsh. But I can't be too judgemental. That's kinda how I feel about the Mesozoic. It's just big chickens, long lizards, and squids wearing ornamental pots.

On the 10th day of fossils, my true love gave to me... A Jovacrinus clarki with 10 arms! I mentioned on Day 1 that Clarkeocrinus is not named after me. However, Jovacrinus clarki is! I found this early Silurian crinoid in Quebec and it was determined to be a new species. #12DaysofFossils

Orthoceras (big) and Lituites

Beautiful granitic glacial erratics from the till back home.

*West Yorkshire 😉

Beautiful Bacillaria paxillifera, a colonial diatom, from today’s sample. #marineplankton 🦑

One day, when I grow up, I would like to paint as good as Mossworm.

Looking forward to trying to stop my family falling for this guff when I get home. My fam think the world of my poc partner who has immigrant parents. They have immigrant and poc friends. But somehow my fam don't see the how bad a reform government would be for everyone.

Some lovely trilobite prep by David.

posting just so I don't forget the name of this fantastic animal again: the land snail genus Whittenia is doing the horrible (said with deep and pure love) Nipponites heteromorph thing with its shell. maybe the worst shell on a currently living thing I've ever seen (I love it)

On the 8th day of fossils, my true love gave to me... 8 Hyperoblastus blastoids from Milan, Michigan. Blastoids are echinoderms related to starfish, sea urchins and crinoids. At some localities they are common. They are very rare at the Devonian Silica Shale Milan location. #12DaysofFossils

Hot take, and not a dig at Dr Pineda-Munoz, but I don't think the GOE extinction really happened. It's a cool story, but I've yet to see any compelling fossil evidence for it. The acritarch assemblages I see pre GOE look the same as those immediately post GOE for example. #Geology 1/n

#MolluscMonday Slab covered by opalised Early Cretaceous bivalves in the public galleries of the South Australia Museum, Adelaide. Not nearly as rare as the ichthyosaur vertebrae posted for the last #FossilFriday, but eye-catching nonetheless.

When I was a teenager, I dated a girl who lived opposite him. He tried to tell her parents that we had been having drunken orgies on her bedroom balcony. But actually, we were just playing connect 4 and drinking panda pop. The closest we got to rowdy was playing a bit of L7.

Looking for a PhD in palaeontology or associated fields? Just a heads up that we have a list of opportunities on the @thepalass.bsky.social website: palass.org/phd-opportun... ⚒️🧪🦀🦑 #evosky (If you're advertising one, you can add it to our listings too: palass.org/form/webform... )

So we er...just not gonna talk about how that Real Ghostbusters meets Gengar looking cucumber has your grandma's false teeth and is clearly thrashing in agony while a breadstick facehugger sucks out its guts? Huh? Merry Seasonsmass.

Day 22: #ArtAdventCalendar This is another new piece from my Lighting the Dark series. Tisha Mark ©2025, Tomorrow's Light, oil on canvas, 12"x12" View the series here: tishamark.com/lighting-the... #art #painting #TraditionalArt #SciArt

Imagine how terrifying this must have been for that crinoid. I bet the other crinoids won't even believe it. "Lads, a giant claw and a massive light tried to abduct me!" "Yeah, sure it did Crinoid Keith. Just like how you have a girlfriend in the next basin, but she never comes to visit."

Furry, forest frog-face

End of year science thread: a few memorable papers that came out this year. Last year I didn't include any paleontology, but this time I'll start with a paper about early animal evolution that I absolutely adore, although I'm biased as a friend of the authors @egmitchell.bsky.social 🧪 1/7

So I actually did this one time and that's how I learned the meaning, but not the correct pronunciation, of forks pass.

Love these weird mossy agates 🏴󠁧󠁢󠁳󠁣󠁴󠁿🖤
