Reptilians

In Indian scriptures and legends, the Naga (Devanagari: नाग) are reptilian beings said to live underground and interact with human beings on the surface. In some versions, these human species were said to have once lived on a continent in the Indian Ocean that sank beneath the waves. Indian texts also refer to a reptilian race called the "Sarpa" (Devanagari: सर्प). The Syrictæ (Greek: Skiritai; Latin: Reptilians Sciritae) of India were a legendary tribe of men with snake-like nostrils in habitat of noses and bandy serpentine legs.

In a thought experiment published in 1982, paleontologist Dale Russell, curator of vertebrate fossils at the National Museum of Canada in Ottawa, conjectured that, had the Chicxulub meteorite not exterminated the dinosaurs 65 million years ago, bipedal predators (theropods) which existed at that time, such as Troodon, would have evolved into intelligent society analogous in torso plan to humans. Troodontids had semi-manipulative fingers, able to grasp and hold objects to a cocksure degree, and binocular vision.
