Steppe bison. Based on my earlier drawings of European bison. I was visiting relatives for the past few days and had practically no time for coherent thoughts. This is what I was able to do on autopilot.

A little fun thing I doodled in a work meeting: Juravenator, a tiny little dinosaur.

Before fish had jaws, they were already a diverse bunch. And quite amusing. Drawn after 3D models by @VilleSinkkonen and inspired by his enthusiasm.

Spiny friend. A male Dacenturus presenting his mating call - which I’m sure is very noisy. Based on the skeletal by Dan F

Another fish, because why not. Ptomacanthus was a Devonian freshwater fish very distantly related to today’s sharks, rays and chimaeras. These animals possibly had a decent color vision, later lost in the shark lineage, and thus could have been colorful.

A warm up sketch of an elderly wolf I photographed some years ago in Ähtäri Zoo, central Finland. Putting tales of big bad wolves aside, most wolves have a quite gentle-looking face. Looking at them, it doesn’t seem to odd our distant ancestors ended up befriending them.

New Paper! Juvenile Jurassic mammaliaform from the Isle of Skye shows mammals grew more slowly in the time of dinosaurs. Our study in Nature uses synchrotron imaging of teeth to look at life history and growth. Thread 🧵 ... nature.com/articles/s4158…

Always feels a bit unreal to see my work in a big publication like this.

Pretty amazing auroras over Helsinki last night. It really was worth getting back up from bed.

I return to share my newly crafted Therizinosaurus design inspired by the Mystics from The Dark Crystal—one of my all-time favorite movies.

Aymberedactylus cearensis, a tapejarid pterosaur from the Early Cretaceous Crato formation, snaps up a small unfortunate lizard from the undergrowth (Calanguban).
