A pile of #lystrosaurus cuddled up in the underbrush!🧡🌿 #paleoart #TheDinosaurMann

New art is arrived ! A large Yutyrannus is being cleaned up by a group of Hongshanornis. A curious Gegepterus approaches. In the foreground, a Zhongjianosaurus seems interested in the small birds. #paleoart #SciArt #dinosaur #digitalart #yixian #china #feathered

I am running in the Palaeontological Association Council Elections, as an Early-Career Research Officer & Meetings Co-ordinator🏅If you are a member of the PalAss, and want me to be part of the council, maybe cast a vote or two? I'd love to fulfill the Early Career position 🤞

My cabbages! An aurochs has broken into a vegetable garden. While curious kids and domesticated cattle watch, a courageous farmer attempts to chase it away. This scene takes place in Poland around 1400 AD. Digital painting by Peter Nickolaus, 2025.

Just when I thought it was safe to pee by myself at night

I can finally share this!!! a huge Thanks to both @skyemcdavid.com and @zhejiang0pterus.bsky.social for allowing me to do a Nyctosaur for this poster!!!

Foggy morning in Late Pleistocene Patagonia. #Art #SciArt #artbyjulio

Years of work and collab with an incredible team at #BBCStudios #AppleTV @framestore.bsky.social ... involving so many camera operators, writers, producers, effects people, artists and others, #PrehistoricPlanetaIceAge is out on #AppleTV Nov 26th. A definitive vision of Ice Age wildlife worldwide.

Oh, that's so not the official #Framestore I tagged there, oops

I'm a bit late to the party with these, but here are the newly described Nanotyrannus lancensis and Nanotyrannus lethaeus, friend-shaped as ever! #nanotyrannus #paleoart #chibi #dinosaur

This exhibit is worse than I could have ever imagined. I actually had a really fun time discovering all the ways it could disappoint me! 😂

in honor of his heroic choice to help Cuomo go down in flames i vote we continue to allow Sliwa to wear his very funny beret

Some dragon sketches.

"An Effort to Release It" Available later today through Strangerfactory.com

lil crop of some birbs. A bunch of the illustrations were sketches, most of them not in color. But coloring this rougher stuff was actually pretty fun~ #birds #sciart #mojavedesert

Later in the day, I'll be streaming with @paleontologizing.bsky.social to explain and answer all your questions, so, you're welcome to join!

I want to thank all my amazing coauthors -especially my mentor Darren Tanke (who first hypothesized the mating hypothesis in 1989 -DARREN, WE DID IT!-), the many institutions that helped me, and the paleoartist Emiliano Troco for the illustrations!

there are MANY "but", "if", and biological implications. The paper is published in OPEN ACCESS so you can read and give me your thoughts 😀

After this evaluation, we realize that the mating hypothesis was the one explaining the pathological pattern at best. The mounting male presses on the female tail, causing the vertebral lesions on top of the spine.

Knowing where we were going, we had to be sure. Or, at least, we had to consider EVERY OTHER SCENARIOS to explain what really looked like something related to sexual activity: predation, locomotion stress, strange and particular behavior, herd stepping... all of them were missing soemthing.

This is the condition for the tails we could check, we also have many other vertebrae in the dataset

Apsolutly fascinating paper. Very intresting ecological and behavioural implications for Hadrosaurids as a whole given this seems to be something seen in both Saurolophins and Lambeosaurins. Congrats on Dr Filippo et al. Also the paper inspired me.

Via Finite Element nalysis, we discover that the spines were stressed by a heavy load coming from above, vertical-to-oblique (around 30-60° degrees). Combine the fact that in that region there is the cloaca, plus the fact that, in articulated tails, the lesions were spread along many vertebrae...

For ABSOLUTELY NO REASONS AT ALL, here the two replica skeletons of the Russian lambeosaurines Olorotitan and Amurosaurus at the Institute of Narural Sciences of Brussels for #fossilfriday … hehehehe 😏👀🦕

Happy #hadroween everyone! Here's two #Olorotitan fighting for dominance.

In live now to discuss recent dinosaur papers, and playing Jurassic World Evolution 3! www.twitch.tv/dicendinosaur #dinosaur #paleontology #twitch

We analyzed the dataset of pathological caudal vertebrae, noting a statistically significance of lesions in the anterior part of the tail. The spines are similarly broken in many different hadrosaur species from different regions and times. Hence, the cause was an event happening for all of them...

After many years of work, submission, tears and swat, we can finally reveal it - hadrosaurids were likely injuring the female partner during sex. For many years, many hadrosaur caudal vertebrae are found possessing broken neural spines, healing, and this has puzzled many researchers...

Our controversial paper is finally out in @cp-iscience.bsky.social ! As part of my PhD dissertation at @qubelfastofficial.bsky.social in 2021, the last chapter was dedicated to a specific pathological pattern in hadrosaurid tails!

fucking screaming. i love guys being dudes

to be convinced. Now that has happened, people like me and @arctomet.bsky.social and @stevebrusatte.bsky.social are saying 'yes, this is convincing, Nano appears to be valid' *because* the scientific method was followed, and *not* because people *thought* that it was. In short...

this should be considered a victory for evidence and proper evaluation of data and science. But I'm sure it'll be considered as vindication that wanting something to be true and arm waving about what someone else said they measured on a specimen no one else had seen, gave the *right* answer.

that had already been dismissed or contradicted in the literature were the way to go and that we should have listened to them. But I and so many others always said that what we wanted to see was convincing data. Proper material, properly studied, with real measurements and testable data...

I'm pretty confident that certain online people are going to be cheering about how they were right all along on Nanotyrannus. Their take will be that they were right all along and their arguments, based on private specimens of uncertain provenance, photos of things without scale bars, and ideas...

See next time just write about fish. No one will care enough to change things for at least a century

Today's bombshell in @nature.com by Lindsay Zanno & James Napoli @jgn-paleo.bsky.social (bit.ly/4qBE6ng) shows that putative juvvy T. rex fossils actually are Nanotyrannus. I reviewed the manuscript, so Nature invited me to write the News & Views commentary. Free link: rdcu.be/eNv94 🦖

Next Tuesday 4th November, sign the date. The time is 17.30 Rome time / 11.30 ET. You are not ready for this. If you like #dinosaur behavior, I think you’ll go CRAZY with my new upcoming paper. The biggest and last chapter of my PhD. Hint: Olorotitan. I think MANY people will talk about this…

Watching some videos on old paleoart and a familiar name showed up: John Sibbick. I didn't realise that the guy I knew best from illustrating the cover of Rogue Trader was also a massively influential artist of prehistoric animals. That is a fact that makes me smile.

Today is Prehistoric Park's 19th Anniversary and i'm just getting a piece made for it, i won't be able to finish it today (i've got a uni deadline to reach) but i promise it'll be something fantastic. #art #wip #dinosaurs

"Darwin-IV, Rayback Sketch" (Another one of my Barlowian bursts of creative mimicry, i still don't know how they occur but i'm quite pleased with it.) #art #BROSKINart #AlienPlanet #WayneBarlowe #Expedition

Preview of my latest #paleoart piece: a baby bison flees the deadliest predator of Ice Age Europe. Harrowing, harrowing stuff.

I got bored

My mom keeps dinosaur figures outside to scare off raccoons who want to steal her garbage. She sent me a photo today. A large toad has found one of the dinosaur figures and befriended it. They are besties now.

Micropernodus is fighting Proscalops for his share of the early worm while a passing Amphicyon looks on. This painting was commissioned by the NPS to celebrate the 50th Anniversary of the John Day Fossil Beds site in Oregon.

the other inspiration is the mexica sun calendar, which represents the cycle of the sun Tonatiuh, starting as Huitzilopochtli, then Tzontémoc as the sunset, becoming the Mictlan sun or the sun of the dead under the earth, and then rising trough the pyramids of the feathered snake, Tonatiuh itself

Tonakaan, jade of wisdom tonati=sun in nahuatl, kaan=snake in maya yucateco tonakaan is a mix of multiple deities as the feathered snake is a constant symbol in mesoamerican cultures, it represents both the earthly (the snake) and the heavenly (the feathers). quetzalcoatl and K’uk’ulkan mainly

or will you pick the jade of wisdom? #fakemon #mesoma #mexicanart

#paleoart #fossilfighters #lowpoly #blockbench well its been fun, this project got me back into 3d modeling and figuring out my low poly style, but thas all of em so here have the blockbench file with the beans drive.google.com/file/d/1JsAc... have fun with em lel

this month ill be posting my mesoamerica and pokemon inspired beans (which i dont think i had posted here before) i have a bit of an aversion to call em #fakemon but thats basically what they are lel, so heres a teaser of the legendaries #mesoma #mexicanart
