The dinosaurs could have died out from a meteor or an ice age. but the real reason they died out was from having to much oral sex. this period of time was called the felacious period. dinosaurs would engage in oral sex at every oppurtune moment, instead of having regular sex to continue the population. it wasnt all in the same species sometimes the larger dinosaurs would be plaesured by the smaller ones in what was known as 'interacial hardcore midget gangbangs'. This theory is supported by all the dinosaur skelotons that have been found in the 69 position and also why there are no dinosaurs left today. the mating call most commonly used by dinosaurs was "do you want a blow job?" the reply to this was normally "yes, you bitch"
