I accidentally deleted what I posted here on #Nanotyrannus and can no longer remember what it said anyway. As a reviewer of the paper, was impressed with the case: more convincing than what's been argued before and substantially better documented; definitely the hypothesis we should prefer for now.

Glazing in watercolour is time-consuming. Though that's perhaps a redundant explanation, given that everything is time-consuming when I attempt it. 😮💨🙁😑

Deinosuchus riograndensis, a robust, and very menacing 9+ meters long eusuchian from the cretaceous, with proportionately giant jaws compared to its body, it was very at home in water, including seas

And here we go, result from the Judith River Formation #paleostream! This late Cretaceous formation might be full of charismatic megafauna but it is currently understudied and a total mess when it comes to stratigraphy. In this scene I wanted to focus on two aspects...

If you’re wondering what a “least weasel” is, they absolutely live up to the name. This is the least amount of animal you can have that can still meet the bar for “is weasel”

No dinosaurs underwent a conceptual transformation as significant as the one undergone by troodontids. We went from creepy monsters, often presented as nightmarish parallels of and terrors to our own ancestors, to a rich and diverse assemblage of toothy quasi-birds. Palaeontology is truly awesome.

Palaeoplatyceros hispanicus- a muntjac-like deer from the Middle Miocene of Spain. Numerous antlers found on Otero Hill in Palencia allow to trace the age-related dimorphism of these animals. The illustration shows an adult, possibly even old, animal and a younger deer in the background.

9-10 November 1938 | The November Pogrom – a pogrom against the Jews throughout Nazi Germany. Hundreds were killed (or died by suicide), 30,000 men arrested and incarcerated in concentration camps, over 1,000 synagogues burnt, over 7,000 Jewish businesses destroyed or damaged.

Elon Musk is not set to become the world's first trillionaire because this pay package has a bunch of preconditions he will never meet. The 600,000 people he killed are dead for real, though.
The world’s first trillionaire initiated a move that has left more than half a million people dead, most of whom are children.

On the coast of Pliocene California, a Homotherium pounces upon a newborn Herpetocetus morrowi. These are Cetotheres, small baleen whales that thrived during the Miocene/Pliocene. For the sabertooth, such a tiny calf so close to shore is a rare treat. #paleoart #sciart #pliocene #california

This one was a bit of a personal artwork, detailing the feelings of isolation and loneliness that comes with moving. As well as depicting my favorite animal of all time.
Probably my most successful of this kind

New drawing of one of my favourite #dinosaurs, Yangchuanosaurus shangyouensis. This is a portrayal of the adult specimen rather than the better known subadult, and is huge for a Jurassic theropod, at least 10 m long. There is an homage to a classic piece of #palaeoart here; IYKYK.
