A black-and-white pencil sketch of a lateral view of a skull and mandible of "Cormohipparion" goorisi, surrounded by the outline of the head as it likely would have been in life.

As the #YearoftheHorse begins, I will share an overview of my recent journey through reconstructing prehistoric horses. For such an important, beloved, and fascinating lineage, there isn't an abundance of paleoart of them (and very little that diverges from established tropes)🧵. #paleoart #sciart

Playing Patch and Release Since I started reworking on what was Aquasauria Park, I have been trying to focus the game’s core loop back on the animals. In today’s devlog, I’ll introduce the loop that I’ve been crafting...

🐊 Major devlog, as I finally closed the gameloop in my game #SoryuHaven! pleistogames.itch.io/soryu-haven/...
For those who don't know me, I am a paleontologist who embarked in an indie solo game dev journey. Follow me if you'd love games with authentic #paleontology creatures!
#indiedev #paleoart

Wow, pretty cool! What's the name of the nothosaur with a flat head / no visible teeth?

Another day, another paleo-devlog! This time, I made a scalable dialog system: pleistogames.itch.io/aquasauria-p...
I also reworked the user interface, I made it a little more... bio-engineery? The character portraits are still from the old jam version, though.
#atmospheric #Godot #gamedev #indiedev

🦕 Time for a new paleo-devlog! This time, I implemented a time controller, I put ichtyosaurs into the bay, made a peak-like health-hunger-disease-wound-bar, and added buttons to feed the ichtyosaurs🐬

Two months ago I took part to the #DINOJAM. The theme was ‘Underwater’, so I developed a marine reptile tycoon game. The result was… underwhelming 😅

So when I learnt about the #ContinueYourGame jam, I decided to give it another go. Read the first devlog here: pleistogames.itch.io/aquasauria-p...

📢Celestial Haven DLC is now available for $2.99 !📢

All revenue will be donated to Animal Charity to take care of abused animals, create shelters for stray cats and more!

We've got something to tell you: NEW GAME!

It's complete!
Enzo the ichthyosaur is now fully on display in the Centre after being discovered just a year ago. A whole lot of work went into this one by Chris and Alex Moore, and Nic Reast and it looks fantastic! #FossilFriday

A sketch of a plesiosaur skull and two swimming plesiosaurs

A little late for the #EuropeanHeritageDays but still: Plesiosaurs are among the most iconic mesozoic marine reptiles of Europe. The first plesiosaur was discovered in 1821 by Mary Anning - a talented fossil huntress and major contributor to paleontology.

Scientists directly date dino eggshells for the first time The new findings narrow age estimates for the clutch of eggs—and may help identify which species laid them

As we're all taught, you can (usually) only directly date the age of a rock if it cooled from lava.

But here, scientists have dated dinosaur eggs, using uranium-lead ratios in the calcite. Hugely exciting, maybe groundbreaking.

My take @science.org

France to return human remains to Madagascar in first action under new law The skulls of King Toera and two warriors were held at Paris's Natural History Museum since 1899

​France's decision to return the skulls of King Toera and two warriors to Madagascar is a significant step toward rectifying colonial injustices. Honoring the dignity of those wronged by colonialism is essential for healing and justice. #Restitution #Justice #HumanRights #France #ForeignPolicy

France has returned the skull of King Toera, a Sakalava king killed by French troops in 1897 during the Ambiky massacre in Madagascar 🇲🇬, along with the skulls of two of his warriors.

What’s better for #MondayMotivation than a giant flying snack? 🍫 🪰 Meganeuropsis was a #Griffinfly, a group of giant #ExtinctInsect from the Permian epoch. Meet them, and other delicious friends, in pleistogames.itch.io/cisuralian-c...

Somehow, the flappy-bird moves of Diplocaulus in pleistogames.itch.io/cisuralian-c... are based on real science! Back in 1980, Cruickshank and Skews used a replica and a wind tunnel to show that tilting the head up while facing the current would propulse it upwards ⤴️

A young Diplocaulus encounters a scary Dimetrodon in the dark during a nocturnal river cruise

Cisuralian Cruise is a free spooky arcade game where you play as a young Diplocaulus, swimming your way through the dangers of the Early Permian. The last update is live at pleistogames.itch.io/cisuralian-c..., and my Dimetrodon is starving to meet you!

Wear marks on trilobite fossil found in archaeological context suggest that the Romans may have used it as ornament.

Very cool find, and a good excuse to bring back this thread on antique palaeontology !

Cisuralian Cruise by Ghislain | Pleistogames A spooky, paleozoic, 3D spin on Flappy Bird.

I did it! Within a single day, I submitted my spooky paleozoic spin on a famous infinite runner to the 2025 #GMTKJam. You can play it here : pleistogames.itch.io/cisuralian-c...

There are tons of things I want to add after the voting period ends. Btw you can leave a vote if you liked it!

Loop, the theme of the 2025 GMTKJam

I am away from home until Sunday... but I've not skipped a single #GMTKjam since 2022, so let's make a super small game fitting the theme, featuring extinct species and a reasonable amount of science - all that within 1 actual day!

Wound repair in plants guided by cell geometry Mathew et al. show that growth conflicts reshape cells after injury, forming rhomboidal geometries that trigger diagonal divisions. This reorients cell files to restore tapered morphology. A two-step ...

Our new paper is out!
1/14 How does an organ rebuild its shape after injury? It's not just about making new cells, but aligning them in the right direction — like bricks shaping a structure. We show that it's all driven by Cell Geometry!

As a kid, and later a paleontologist, I was so thrilled to see actual mummies and early human skulls in France. I wish a game like #Relooted by @nyamakop.co.za existed at the time.

(also don't actually heist human remains, you could damage them and you may jeopardize ongoing restitution efforts)
