But dinosaurs didn’t die out. The finch peeping incessantly outside the window right now is a real live annoying little fuck of a dinosaur and is not extinct. Nor was the chicken you ate last night. Well, that particular chicken is extinct, but not the entirety of chickenness. However, non-avian dinosaurs died out–duck billed whatevers and spiky triceratops and clunky ankylosaurs and vast and bulbous titanosaurs. They all went poof instantly or not long after the meteor hit and volcanos belched. As did soaring pterosaurs and swimming mosasaurs and paddling plesiosaurs. Even polyglyphanodonts went extinct at the end of the cretaceous. True, they were only lizards, maybe three feet long and not the least bit scary, but I only posted this so I could say polyglyphanodont. Polyglyphanodont. Polyglyphanodont. Polyglyphanodont. Too much fun.
