Sinornithosaurus by Mick Ellison.
From Archosaur Musings’ interview with Mick Ellison:
What do you think is the most important part of good palaeoart?
For me it would be believability. Can I picture this animal as a living, breathing animal? Is it natural? Those are the questions that come to mind first.
It’s a hard thing to pull off. I think you have to avoid the conventions and traps of paleo art, because you have a lot of people simply copying other people. I also think it helps when the art draws from the natural world, and from the appearance and behaviors of modern animals that may share traits, or live in similar environments. It’s often the subtle small details that work best to convey that sense of reality.
