They were one of the first mesozoic animals to be given a name, beating the first named dinosaur Megalosaurus by 60 years! (1764 for the first named Mosasaurus, 1824 for Megalosaurus, the first named Dinosaur)

I tried to be as precise as possible (while keeping a cute/cartoony style) in the reconstruction of this critter and took large inspiration from Fabrizio De Rossi's illustration on Pteros.com, adding only some little stripes to show its juvenile coat. I'm not sure about the environment and wether or not rolypolys were a thing... I read that plants in late Triassic were mainly conifers, and specificaly I tried to draw Aethophyllum stipulare, an herbaceous conifer plant.
I am not a naturalist tho, just an amateur, so if you have any criticism I'll gladly take it!
Yes, it was that big... 🐉

Today's competitors are very, very closely related to dinosaurs...so much in fact, that both were thought to be dinosaurs for a while.
Why isn't Silesaurus a dinosaur?
1.) Lacks an elongated deltopectoral crest (ridge on the humorus for muscle attachment).
2.) Lacks epipophyses on cervical verts (parts that branch off the vertebra)
Pisanosaurus, not a dino? This little guy is still under hot debate. It could be a transitional form between silesaurids and basal ornithischians OR is could be a basal ornithiscian. More data is needed.
“Mosasaur so Happy to See You” a friend of mine on Facebook has some mosasaur vertebrae that she posted pictures of, so of course that inspired me to draw one! Plus, I’ve never drawn one before. Fun fact, mosasaurs are not dinosaurs. They are a whole group of giant aquatic sea lizards who existed simultaneously with the dinosaurs, during the Cretaceous period
Pleistocene to Holocene. 125,000 to 9,500 years ago.
We now know their range extended into Eastern Asia! Before the discovery of a piece of mandible in Eastern China, we thought they only lived in North and South America.
