Everyone interested in the subject has thought thought about it once or twice: What if dinosaurs, instead of dying out, survived to produce a sentient species? Products of primate chauvinism, current models of erect, humanoid sentient dinosaurs are hopelessly wrong. An intelligent dinosaur, descended perhaps from arboreal Dromaeosaurs, would have a horizontally slung body, digitrade feet and other features that would identify it proudly as an archosaur. Inspired by zoologist Darren Naish's article on ground hornbills and intelligent dinosaurs, I felt the need to redesign the old Dinosauroid concept. I came up with the creature above, Avisapiens saurotheos. Posted online, it got mentioned in Darren Naish's weblog and attracted an unprecedented surge of visitors. So I took the process further. As an intelligent species, how would Avisapiens perceive its world? How would they organize their societies, and how would they depict their everyday lives? The pictures you see in this project are primitive dinosauroid cave art, made about twenty million years ago on a parallel world where they did not die out. No matter how different their biological heritage is, all sophonts express the symptoms of intelligence through their art. Behold the life of Avisapiens.
