Antarctican coelophysoid.

This is another pencil and digital sketch completed for the July-September 2010 issue of Answers Magazine. The animal depicted is Cryolophosaurus ellioti, a 6 m (20 ft) long dilophosaurid from Antarctica. The holotype--a partially complete subadult--is the only known specimen.
While this image is a decent representation of the animal, there are definitely some elements that I'd like to modify in the future.

Antarctican ankylosaur.

This is a pencil and digital sketch that I completed for the July-September 2010 issue of Answers Magazine. It appeared in an article by Buddy Davis titled, "Antarctica—Dinosaurs on Ice."  The image is a life restoration of the medium-sized ankylosaur, Antarctopelta oliveroi.  Fossils have only been recovered from a single, fragmentary and inarticulated specimen, so the image above contains a lot of conjecture.

Psittacosaur.

Here is an unfinished pencil-on-illustration board sketch from 2009.

This dinosaur is the prototypical psittacosaurid, called Psittacosaurus mongoliensis. P. mongoliensis is known from China, Mongolia, and Siberia. Fossils of P. mongoliensis are so abundant, nearly a full skeletal ontogeny is known for the species. At least one species of Psittacosaurus (and there are many) exibited a patch of long, moderately-flexible and hollow bristles along the dorsal surface of its tail.

As promised....

Here's a larger version of my B. walkeri image.

Baryonyx image.

I'll post a larger, watermarked version in the near future. If anyone has any questions regarding the piece or the animal, just let me know and I'll address it a.s.a.p.
