A world of dinosauroids (with Simon Roy)

There are two highly-popular, vexing questions about dinosaurs: What would the world look like if these strange and majestic animals had not gone extinct? And, would they ever evolve into intelligent species comparable to humans? In 1982, palaeontologist Dale Russell, after observing "... a general trend toward larger relative brain size in terrestrial vertebrates through geologic time, and the energetic efficiency of an upright posture in slow-moving, bipedal animals", postulated the Dinosauroid , a humanoid, erect-gaited sophont which may have evolved from Troodon-like dinosaurs had the end-Cretaceous extinction not occurred.

This question occupied the minds of yours truly (seen here on the right), and world-building comic genius Simon Roy (on the left), as well. We were unconvinced by Russell's Dinosauroid. We thought that an erect, humanoid sophont was too prejudiced towards humans to be realistic. We were instead inspired by zoologist Darren Naish's writings on the evolution of intelligent, bird-like dinosaurs: "No, post-Cretaceous maniraptorans wouldn’t end up looking like scaly tridactyl plantigrade humanoids with erect tailless bodies. They would be decked out with feathers and brightly coloured skin ornaments; have nice normal horizontal bodies and digitigrade feet; long, hard, powerful jaws; stride around on the savannah kicking the shit out of little mammals; and in the evenings they would stand together in the trees, booming out a duet of du du du-du, a deep noise that would reverberate for miles around..."

Towards the end of the '00s, Simon Roy and I independently began to develop our concepts for bird-like intelligent dinosaurs. Inspired by the ravens he saw around his Canadian home, Simon drew the corvid-like dinosauroids seen above.

I, in turn, was inspired by ground hornbills, parrots, certain dinosaurs and corvids, and came up with the speculative organism seen above. I named it Avisapiens saurotheos.

Simon and I soon got in touch with each other; and started developing a world and a storyline for our dinosauroids. Our collaborative efforts continued, on-and-off, until the mid-2010s. Our aim was to develop the Dinosauroids story into an illustrated story-book, which we naively hoped to sell to a major sci-fi publisher. But we soon realised that we enjoyed world-building more than writing a story, or putting a book together. We kept bouncing concepts back and forth, but never had a chance to publish them, until now. Most of the body of work you see on this page was drawn by Simon, based on ideas we created together. I also contributed some of the "cave drawings" and certain creature illustrations. This is the first time the totality of our Dinosauroids-universe works has been displayed online.

Simon and I refined the design of my original Avisapiens dinosauroid...

And created a few more sentient races to accompany them. There was one more, slightly-crow-like species of Avisapiens (a continuation of Simon's corvid dinosauroids - Avisapiens tataricus). These two species were joined by a variety of "forest giants" (Gigantosapiens borealis), and a race of pygmies (Avisapiens minimus).

Simon's refined studies of corvid-like, and pygmy dinosauroids.

We also designed an extensive selection of animals around our dinosauroids. We predicted that even without the K/T mass extinction, dinosaurs and other animals would have kept on evolving, and many "familiar" groups of dinosaurs would have gone extinct. We thus designed a world where the majority of surviving dinosaurs were the descendants of "maniraptoran" groups; birds, deinonychosaur ("raptor") dinosaurs, troodonts, oviraptors and therizinosaurs. Here, you can see two boreal dinosauroids using mouth-spears to hunt herbivorous troodont quarry.

We also did not want this world to be devoid of mammals. Even during the age of dinosaurs, certain mammals evolved into large and sophisticated forms. We envisioned a world where parallel groups of mammals, similar to, but phylogenetically distinct from today's forms, co-evolved alongside the dinosaurs during their continued reign. The scene above shows an Eurasian water-hole crowded with two species of ornithomimid herbivores (Rugocursor, left-centre; and Cyanogularia, far right); alongside robust (Afrotuberculocamelus) and gracile (Odontocervoides) species of herbivorous mammals which, for the lack of a better term, we decided to name "supermaras".
