After four months and 36 illustrations, I present the final Kem Kem chart – a look at of one of the most incredible ecosystems the world has ever seen. Short thread below! #sciart #paleoart

👀

Excited to announce that my second manuscript, “Fossilised Melanosomes Reveal Colour Patterning in A Sauropod Dinosaur” has been published in @royalsociety.org !! Diplodocus scales are complex and diverse, and it turns out their color patterning was even more so. A 🧵🦕 1/26

“Dragging a ladder through long rows of bookshelves can be exhausting. It’s much more efficient to have a co-worker who’s able to reach the top shelves on their own or at least give you a boost climbing up.” #miragaia #stegosaur #dinosaur #paleoart #library #librarian #books

New species of jewel-babbler, the hooded jewel-babbler (Ptilorrhoa urrissia), described based on individuals pictured in camera trap photos: onlinelibrary.wiley.com/doi/10.1111/... 🪶🧪 (📷Woxvold et al.)

Buffa et al.’s paper on the enigmatic Permian reptile 🦎 Galesphyrus and the origin of Neodiapsida is out in the Journal of Systematic Palaeontology! Read the thread 👇 for some important takeaways from our study @valentinbuffa.bsky.social #Paleontology #Reptile #Permian doi.org/10.1080/1477...

Nosso bebê nasceu 🥹 Uma nova espécie de pterossauro do Araripe, encontrada dentro de um vômito fossilizado de dinossauro 🤍. A natureza é linda! Kkk Seja bem-vindo, Bakiribu waridza! Acesse o artigo: www.nature.com/articles/s41...

JUST PUBLISHED!!!! A major azhdarchoid phylogeny paper coauthored with @skyemcdavid.com - the fruit of years of work - is now out in @journalsystpal.bsky.social! New clades, reconstruction of size evolution, and more. Full thread to come soon! www.tandfonline.com/doi/full/10....

An interesting quirk of today's taxonomic revision is that one jacket from the Jane Quarry, long assumed to contain specimens of famous species, actually contained what would become two holotypes of two distinct species — Infernodrakon hastacollis and Nanotyrannus lethaeus

Did some giraffes and forgot to post them: Canthumeryx, Climacoceras gentryi, Georgiomeryx, and Palaeotragus inexspectatus #paleoart #scieart

Qilin tungurensis- A newly identified new genus of giraffe from the Miocene of Inner Mongolia, China.

Meet the newest species of Brazilian flea-toad 🐸 Brachycephalus nanicus! 🐸 B. nanicus is <1cm long & dwells under the leaf litter in the cloud forests of Serro do Mar, southeastern Brazil I CT scanned this specimen for the osteological description Out today in Zootaxa: mapress.com/zt/article/v...

Reconstructed skeleton of Spicomellus ('spiky collar'), certainly one of the most unusual dinosaurs known. Found in the mid-Jurassic El Mers Group of Morocco, it is also the oldest definitive ankylosaur.

Last week in Nature: ooo look at my spiky dino. This week in Nature: EVERYTHING YOU KNOW ABOUT BIOLOGY IS WRONG www.nature.com/articles/d41...

In fact, we suggest that the tympanum of modern reptiles originated in the common ancestor of Parapleurota in the middle Permian. Excitingly, recent developmental work by Bronzati et al. has shown that the modern reptile tympanum was present in their common ancestor, congruent with this hypothesis

Fantastic work by Xavier and team, many years in the making ~ So many important implications for our understanding of reptile (and broader) relationships. More to come soon! 🦎

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!!

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

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....

And I named one of them!!! Meet Aulacephalodon kapoliwacela - the Iron Hog - the first and so far only geikiid known from the Luangwa Basin! I worked on this taxon for my Master's thesis, and it's been lovely

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:

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

Everyone, please meet Sphenodraco! A newly described sphenodontian (a tuatara relative) from the Late Jurassic of Europe published TODAY! #paleoart #reptiles #sciart #art

Southern #Sweden during the late Cretaceous. A pair of pteranodontids trying to keep a healthy distance from an admittedly passive mosasaur. Meanwhile, the hesperornithids take a short break from foraging to catch some rays. #paleoart #sciart #scicomm #dinosaurs

Khankhuuluu ("dragon prince") is a recently named tyrannosauroid from Mongolia's Bayanshiree Formation. 🦖 This reconstruction includes the holotype (white) and a slightly smaller referred specimen (pink). Both scale bars = 1 m.

New #paleoart for #FossilFriday: battling Borealopelta with deep (instead of "high waisted") armour and pigmentation. There's a scientific rationale behind this #ankylosaur #art, which you can read here, along with viewing the hi-res and WIPs of the painting. www.patreon.com/posts/130274... #sciart

happy #PrideMonth btw #gayleoart #paleoart #sciart

In another post, I discuss the evolution of different types of phytoplankton: what it means for the appearance of our planet and animals that ingested them. When did marine carotenoids become abundant enough to turn the animals that ate them pink and red? The early Mesozoic, probably? (3/4)

To those who celebrate... #VelociraptorAwarenessDay

Happy I was able to assist at the St. George 'Substation Quarry' last week with others from the @imnh208.bsky.social! My personal highlight was finding a decent theropod tooth among several fish scale fragments. 🦖

Extremely detailed paper on the anatomy Thadeosaurus, with increased phylogenetic support for Tangasauridae 🦎 🌊 onlinelibrary.wiley.com/doi/10.1002/...

If you see this QRP with your animal painting: Semi-stylized watercolor + ink sketch of a pygmy squid! 🦑

Here is my reconstruction of Millereta rubidgei, an early #reptile from Late Permian South Africa. It has osteoderms on its head. I was commissioned to do this recon for a redescription published yesterday! Congrats to @semifossorial.bsky.social and colleagues for such a cool paper! #paleoart

And our amazing artwork of Milleretta, brought to life by @serpenillus.bsky.social 😀 #Permian #Fossil #Reptile #Paleontology

Our description of Milleretta rubidgei, a 252 million-year old reptile, is out! academic.oup.com/zoolinnean/a... #Permian #Reptile #South Africa

Trotting this out again for #WorldWildlifeDay. Thirty Animals, each drawn at 1" square. Pencil on marker paper, 2018.

JUST OUT!!! Happy to announce my first publication, coauthored with @davehone.bsky.social, Tim Gomes, and Joseph Peterson. Meet Infernodrakon hastacollis - a new name for the azhdarchid from the Hell Creek Formation! Life restoration by @jhemiptera.bsky.social

If you see this, post a skeleton

Today I've discovered an animal called "Skeleton panda sea squirt" exists. A sessile, filter feeding tunicat.

As the herbivorous dinosaur Iguanodon was named officially 200 years ago today one of my favourite illustrations of the beast by the brilliant artist John Sibbick.

@gondwannabe.bsky.social and I had a blast working with students from Loyola and the Idaho Museum of Natural History this week on developing our curation system of Lance Creek micro vertebrate fossils. Special thanks to the @burkemuseum.bsky.social for hosting us! #FossilFriday

Here is a large #dinosaur limb bone for #FossilFriday! This #Idaho #fossil is from a big meat-eating dinosaur that lived in the #Cretaceous Period. There are tantalizing pieces that are helping some of us (@ljkrum.bsky.social @slvrhwk.bsky.social & other) piece this #IdahoPaleo story together.

🚨 Big plesiosaur news 🚨 Our paper is out. We describe pigment cells and scales in a Jurassic plesiosaur. Small scales are found at the limbs which enforced them. Body and tail are scale-less. Many thanks to lead-author Miguel Marx & the team. www.cell.com/current-biol... #Science #News #Nature 1/3

Dance of Tanystropheus

Dearc sgiathanach, one of the largest well-preserved pterosaurs from the Jurassic, now fully analysed! The description of this toothy Scottish fella, hot off the press, hit BMC E&E. But what does it tell us about pterosaurs? 🤔 bmcecolevol.biomedcentral.com/articles/10....
