The dinosauroid is a concept created around the 70's and 80's, based on the hypothesis that if the non-avian dinosaurs had not been eliminated in the Cretaceous–Paleogene extinction event, they would have continued to evolve and develop to a point where some or many dinosaur species would possess an advanced intelligence, at a similar level to human beings. These representations of this possible hypothetical sapient dinosaur at first were described as humanoid creatures, however in present times, this vision changed radically due to the inconsistencies that occurred in the humanoid model and preserving the theropod shape.
History[]
The idea of possible intelligent descendants of dinosaurs had been described in different types of media, including Car Sagan's book The Dragons of Eden: Speculations on the Evolution of Human Intelligence, where he mention a possible descendant of Saurornithoides if these never became extinct, having a "base 8" arithmetic system.
The most familiar concept of all is probably the one created by Dale Russell around 1982, with the candidate species in this case being the Troodon. This was established under certain criteria, including the postulation he put forward that there was a steady increase in the encephalitic quotient, or 'EQ', among dinosaurs (the relative brain weight when compared to other species with the same body weight) and observed that Troodon's EQ was nearly six times greater than that of other dinosaurs, though it was still well below that of humans. Under these calculations, he inferred that the rate of growth over the millions of years would have culminated in the development of a brain with the same capacities as ours. Other features speculated on this model were also the development of opposable articulated digits in the forelimbs, widely considered to be extremely advantageous for tool use. As various reptiles and birds their genitals would not be visible, the way they would feed the young would be regurgitated and their mode of communication would sound like birds.
After a few decades with this model, with new discoveries about dinosaurs and with new interpretations and speculations, new theories had arrived to reinterpret the conclusions about how sapience in dinosaurs could evolve and how these could look.
