Dinosaur Sketches

I have been scanning in some drawings, and found a few dinosaurs that I like:

The shading shows some loose skin on this sauropod.

This is some sort of lightly built therizinosaurid, perhaps Erlikosaurus. While most dinosaurs held their spines horizontally, parallel to the ground, the therizinosaurs held their backs up at an angle from the ground.

This is a speculative creature that evolved in the Squawk Role-Playing Game universe. In the millions of years since hadrosaurs and other giant dinosaurs disappeared from our world, mammals have evolved from squatty short-limbed critters into a variety of descendants, including graceful forms like deer and wolves. In the Squawk universe dinosaurs have also evolved long-limbed, graceful forms like this hadrosaur.

Zephyr

In the Squawk Role-Playing Game, zephyrs are small intelligent hadrosaurs with a single ridged horn as a crest. Originally they were conceived as furry creatures with a zebra-like mane and stripes.

However, we have extensive information about the skin of some hadrosaurs like the "trachodon mummy" discovered in 1908. The interesting skin of real-life hadrosaurs is covered in fine scales with patterns, wrinkles and variations that suggest how the creatures might have been colored in life. Hadrosaur species also had distinctive frills running down their backs.

Inspired by the skin impressions of these and other herbivorous dinosaurs, we have redesigned the zephyr to have smooth skin covered in tiny non-overlapping scales and a "mane" which is actually a frayed dorsal frill.
