A theory that dinosaurs were intelligent beings from another galaxy that ruled the earth from the Triassic through the Cretaceous period of the Mesozoic Era.
Upon discovery that the earth would be struck by a meteor roughly 60-160 kilometers in diameter, most of dinosaurs left the planet in giant mother ships before the "shit hit the fan."
The remainder of the population, mostly stoner's and hippie dinosaurs stayed behind to philosophize the meaning of life and what the fuck a Doyouthinkhesaurus Rex is.
The meteor struck and the remaining dinosaur population was completely wiped out. We now ponder, with their brothers and sisters extinct, when will they return...
Did you know "The Land Before Time" was based on the Bilslendium theory? Fuckin unreal!
