Teenage Mutant Ninja Turtles artist Jim Lawson is serializing Paleo, his comic about late Cretaceous dinosaurs online. Not really a paleontological rigorous comic, but the story of a group of tyrannosaurs, pretty anthropomorphized.
As Jim said, the progect Loner since a year has sat on a shelf. So he decided to publish the comic in the internet, on a dedicated blog: http://paleo-loner.blogspot.com/
