#temnovember2025 day 3: Tupilakosaurus Third day of #temnovember and hey look at that, we have the name shake of a family,#Tupilakosaurus , the tupilakosaurids are small and long dvinosaurs from the early #Triassic #paleoart #sciart #temnospondyl #amphibian #dvinosaurus

New paper in JSP: Gonçalves & Luccisano reassess the taxonomy and phylogeny of Aeduellidae, Carboniferous ray-finned fish from Decazeville Basin, France 🐟 Results hint at a North American origin… or convergent traits that muddy the family waters. Read the study: buff.ly/huDEsiU #paleosky #fossilfish

One of the largest temmnospondyls ever to exist: the gigantic Koolasuchus was also the last non-lissamphibian temnospondyl to exist. It survived into the Early Cretaceous of Australia when all other stereospondyls were long gone #temnospondyls #paleoart

#Temnovember a study of the Jurassic temnospondyl Sinobrachyops, which lived alongside mamenchisaurs. Smaller than I picture temnos! Partly inspired by the work of cqin & Emily Stepp. Larva is speculative & not to scale

#temnovember2025 day 2: Acroplous And now for the second day of #temnovember, we have #Acroplous, an a basal dvinosauroid from lower permian of northamerica, known from multiple localities and specimens #paleoart #sciart #amphibian #temnospondyl #dvinosaurus #permian

This is a super cool paper from the Hejnol group that should be a top reference for a lot of animal biodiversity/zoology courses.....origins of the bilaterian anus from the gonopore. Just drop this figure right into your slide deck. www.nature.com/articles/s41...

C'est la 29e Réunion des Sciences de la Terre à Montpellier toute la semaine 🌐🌋🦕 Demain après-midi je parlerai du changement de végétation dans la zone tropicale fin Carbonifère-début Permien avec l'exemple des flores de Graissessac & Lodève (session 8.1)⛏️ 🌿 #paleobotany #geosciences #paleontology

Happy #FossilFriday! Today is my last day at the AMNH before I return to Oxford so in honor of that here’s one of my favorite fossils on display here, a full skeleton of Cotylorhynchus romeri! Cotylorhynchus is a caseid, which were among the earliest large terrestrial herbivores on Earth! 🧪⚒️🦊

This #fossilfriday , I wanted to post a very classic Pittsburgh fossil. This is Fedexia striegeli. It’s known from only one specimen (shown here) that was collected during a geology field trip to a roadcut near Pittsburgh in 2004. I credit it as the specimen that made me interested in local verts!

Yesterday we opened “Triassic Life — Dawn of the age of reptiles” at Museum am Löwentor, Stuttgart. The show tracks life’s rebound after the end Permian mass extinction ~252 million years ago. 📷: Maximilian Schwarz

After two years of hard work, I’m proud to announce that our new special exhibition @smnstuttgart.bsky.social is now open for the public – Meet Triassic Life: Dawn of the world of reptiles (1/7).

Koolasuchus cleelandi Illustration! In this Illustration, I have depicted a scene of koolasuchus making a desperate attempt to flee the dangers of a fellow Koolasuchus. The seasonal flooding has brought new hunting grounds, and so more competition and fights for those hunting ground rights #paleoart

And that's how you integrate digital elements into an exhibition. Part of the temporary "China's Dinosaur World" at the Shanghai Natural History Museum, China. Closing this November. Video source: Shanghai Let's Meet

A pair of beautiful Carboniferous tetrapod skulls on display at the University of Kansas Natural History Museum for #FossilFriday

It’s extremely rare to find an entire skeleton of a fossil amphibian. But that’s what this is – except for a few missing pieces of the hands and feet and the very tip of the tail. #novascotia #fossilfriday

Interesting use of lithium isotopes to test for habitat specialization in Miguasha vertebrates. Notably, the authors find evidence for marine occupancy for tetrapodamorphs Eusthenopteron and Elpistostege, compared to freshwater occupancy in other common taxa. www.sciencedirect.com/science/arti...

Chameleons & salamanders evolved a sliding-based linear actuator to launch the tongue via muscular squeezing of a tapered skeletal rod, contrasting with tendon-driven pulling mechanisms common in most musculoskeletal systems, allowing acceleration along a straight path. www.cell.com/current-biol...

Excited to share the first paper from my PhD! We looked at what traits help Aneides salamanders excel at climbing using museum specimens, CT scans, SEM, and more! No claws or toe pads, so how do they do it? In short, with long limbs, big feet and grippy toes! 🦎🧪 DM for PDF doi.org/10.1098/rspb...

🚨 REPTILE ALERT 🦎🐍🐢🐊🦉 The backbone of @semifossorial.bsky.social's PhD in my lab is finally out after literally *years* in review, and it's a doozy. Using synchrotron micro-CT scans of MANY amniotes and Paleozoic reptiles we completely restructure the reptile stem lineage across the Permian. 🤩

It’s finally out! Our work addressing the origins of reptiles is published in PCJ! peercommunityjournal.org/articles/10.... We use novel info gleaned from the scan data of dozens of stem reptiles to substantially revise our understanding of early reptile evolution #paleontology #herpetology

Huge thanks to Michel Laurin for his recommendation of my work on reptile origins in PCI Paleontology! First of many works to come (: Also thanks to Valentin Buffa, David Majanović, and others for their reviews (: paleo.peercommunityin.org/articles/rec...

An ephemeropteran, or mayfly. In Germany, we say ‘Eintagsfliege’ (one-day fly). May-be because it wasn't very careful with its wishes: "Just one day in the Permian, only one day!!"

An awesome study. PETM as a turnover/heterochrony pulse and the modulator of developmental modes in salamanders in the post-event world. More to the ideas of Elisabeth Vrba on taxonomic turnovers and developmental overturns. royalsocietypublishing.org/doi/10.1098/... 🧪 ⚒️ #Paleobio #EvoBio #Geology

Our study on the role of the #PETM on the early evolutionary success of #salamandrids is out! Delighted to be part of this great project led by Loredana Macaluso, with A.Villa, @grumpydrfabre.bsky.social & B.Mennecart #salamanders #climatechanges 🌡☀️⌛️ royalsocietypublishing.org/doi/10.1098/...

A scene of ca. 252 million years ago during the Late Permian in the Madumabisa Mudstone Formation in Zambia, Africa. You can see here various therapsids and a Pareisaur #paleoart #art #permian

Eophrynus prestvicii, the Coseley Spider, is an extremely well-preserved, 300-million-year-old #arachnid discovered near Dudley. Though it looks like modern #spiders, it was unable to spin a web, instead catching prey using powerful jaws! #FossilFriday #LapworthRocks #geology #palaeontology

Now introducing Amenoyengi mpunduensis ('many-tooth from Mpundu'), a small moradisaurine captorhinid from the late Permian of Zambia with multiple rows of teeth! #Permian #Paleontology 😄 www.tandfonline.com/doi/full/10....

Other new species from Permian Zambia described in the JVP memoir include the temnospondyl Rhineceps karibaensis, the gorgonopsid Arctops umulunshi, and the captorhinid Amenoyengi mpunduensis

As of this morning, SVP Memoir 23 - Vertebrate Evolution in the Permian Rift Basins of Tanzania and Zambia - has been published!!! What's inside? Let's dig in:

More exciting news! I am now able to share with you more of the concept art I did for the amazing upcoming NBC Universal show “Surviving Earth” premiering next year! This time for a fan favorite, Dimetrodon! I can’t say much more than this for now 🙊

#paleoart In Carboniferous lake of Montceau-les-Mines, Platysella descusi is trying to bother Palaeocampa anthrax. Palaeocampa curls up and bristles up in defense. Two Palaeocaris secretanae and single Nyranerpeton montceauense are swimming nearby.

I am proud and grateful to present a dream project today in @nature.com www.nature.com/articles/s41... Meet #Mirasaura grauvogeli, a #wonderreptilewith skin appendages that rival feathers and hairs, challenging our view of reptile #evolution🪶🦎

Here it is! Please welcome the AMAZING Mirasaura grauvogeli, a NEW MARVELOUS Drepanosaur published in NATURE today! This astonishing reptile lived during the Middle Triassic in Europe and it possessed an amazing crest made of plume-like structures! I was commissioned to bring it to life #paleoart

Meet Palaeocampa anthrax, a newly discovered Carboniferous lobopodian, and 150 year old mystery fossil! Palaeocampa is an exceptional lobopodian - it lived in rivers and lakes, bristled with thousands of poisonous spines, and more. 🧵 Open access: nature.com/articles/s42...

Great to see this finally out today! We show that the collapse of tropical vegetation during the Permo-Triassic extinction is a key driver of the long-term super-greenhouse climate that followed it. Read more at www.nature.com/articles/s41...

Fieldtrip day 1: today we visited not 1 but 2 sites with fossil plants 🌿⛏️🤩 Here's a nice Stigmaria, the rooting structure of a lycopsid tree from the latest Carboniferous, a little over 300 million year ago. (and yes it is extremely warm 🌡️)

An old snapshot from my collections visit to the Field Museum for this #FossilFriday. Here you can see a #Diadectes jaw & some of my notes. Such diadectids lived during the #Carboniferous & #Permian & were among the first herbivorous tetrapods to evolve. #paleontology #science 🧵 1/

New paper led by Tash Prescott - we applied equations for speed, etc that are commonly used on #dinosaur tracks to tracks made by living birds we could watch and time. TLDR: equations aren't even nearly close. Animals moving freely on compliant substrates very different to steady-state lab data
