I want to wish everyone Merry Christmas and Happy Holidays with this quick sketch of two Microraptorine dinosaurs in the snow ❄️. I hope everybody is having a great day and enjoying the presents! 🎁 🎄 🎅

I tidied up this little thumbnail (of approximately 100 × 60 mm). It's all I could manage for now. 🥲

I have finally watched Prehistoric Planet: Ice Age!!!
I guess that the fact that it made me obsessed with the Ice Age and Pleistocene megafauna means it hits the point.
It is sooo good!
Some more thoughts coming soon 🧵

And this one with an Edmontosaurus is from 2013.
It was commissioned by the science faculty of the University of Alberta as their Christmas card that year. In the event, they didn't reproduce the image in full but cropped it heavily, losing much of the composition and its various elements.

I have been away from social media for a while, not only because I was overwhelmed by recent political events, but also because it appears that studying natural sciences in France is much more stressful than in Italy. But now I'm getting used to my new university and... I'm back here on Bluesky!

Tyrannosaurus rex was named 120 years ago today on 4th October, 1905.
I would do things a little differently now, but this drawing is from 2020.

#ZAVACEPHALE IS FINALLY OUT! 🥳 Our first definitive Early Cretaceous pachycephalosaur! (~15 my older than the previous oldest pachycephalosaurs) And the first hand material for the clade! I can't tell y'all how much of a pleasure it was to review this paper! ☺️

I haven't been posting for a while because I was moving to Lille, France to join a Master's Program in Palaeontology! Starting to live here has been tough, but I can't wait to start my studies...

In our most recent #fossil prospecting excursion we went to a #Carboniferous outcrop on the Little St. Bernard Pass (French-Italian border) together with french colleagues. What was once a coastal swamp covered by lush vegetation is now located at 2.2 km of altitude, surrounded by a scenic setting.

🪶Red-whiskered bulbul (Pycnonotus jocosus).
Watercolour on paper-backed silk, 114 × 165 mm.
Another bird which seared itself into my childhood memories in Chiang Mai. We in the North know it as นกปิ๊ดจะลิว ('Pitjaliu bird') after its call, though its Thai name is นกปรอดหัวโขน. 1/3

Today's random piece of nostalgic palaeoart: Zdenek Burian's "Brontotherium" (Megacerops)
As with many of Burian's paintings, this was a major work in defining the way its subjects were imagined for decades to come, only overshadowed by Charles Knight's older, more rhino-like reconstructions. (1/5)

This impressive crest of #Mirasaura had densely overlapping individual appendages with feather-like contours. But our work shows these are unlike true feathers and indicate an independent evolutionary origin 🦎🪶

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

Interesting thread on a wonderful discovery made on a Temnodontosaurus (an ichthyosaur) fossil. This genus has been studied since the early days of Palaeontology, and finds like this remind us how much we still don't know even about the most familiar fossil taxa.
Oh BOY! Story time!
All the way back in 2016, on our way back from Munich for a EAVP meeting, @dinosven.bsky.social got a mail by Georg Göltz, attached were some first images of an incredible specimen. That evening we went over the material again and again...
