Once upon a time, in the autumn of 2011, I submitted an artwork requested by one Scott Persons of the University of Alberta via Art Evolved... Three years later, the resulting set of three illustrations — a race between an Olorotitan and a Tarbosaurus — was finally published in the press release for a study of hadrosaur locomotion by Dr. Phil Currie and Scott Persons, which a few readers may already be familiar with, either independently or via the Chasmosaurs Facebook page.
