*joke* The real cause of the K/Pg extinction



From the latest Geology issue...

*Combustion of fossil organic matter at the Cretaceous-Paleogene (K-P) boundary*
Mark C. Harvey et al., 5/26 Picton Street, Ponsonby, Auckland, New Zealand. Pages 355-358.


Harvey et al. have discovered curious, tiny smoke particles in sediments deposited during the dinosaur extinction event. Close examination of the distinctive particles revealed a striking resemblance to smoke from industrial burning of coal and oil. Because this type of smoke cannot be produced by forest fires, the likely explanation is that the Cretaceous-Paleogene meteorite struck and ignited an oil field. In fact, one of Earth's largest known oil fields lies next to the meteorite crater in the Gulf of Mexico. The meteorite impact would have released enough heat to burn vast quantities of oil, injecting massive amounts of carbon dioxide into the atmosphere. This carbon dioxide may have caused an interval of intense global warming, contributing to the extinction of the dinosaurs.

...but I had the horrible thought that the dinosaurs had developed an intelligent species who proceeded to exploit the oil resources and they polluted themselves to death. It's a bit like the silly kids' show "Planet Sketch" which gives reasons for the extinction prefaced by "60 million years ago last Tuesday, the mighty dinosaurs became extinct. There were many reasons for this. Here is just one of them..."
