Tsintaosaurus spinorhinus was a 10 meter-long Chinese lambeosaurid hardosaur (duck-billed dino) which lived in the late Cretaceous. It displayed a unicorn-like crest at the top of it's head and probably lived in herds eating vegetation.
The sketch above was created using pen and ink on white paper, while waisting time at work waiting for students to not show up... I love the detail on it and it's skin texture. I also really like the pose of it's neck - curved and foreshortened!
In other news, Iron Man opens here in Seoul tomorrow. I'm checking out the 12 noon showing!
