Soot may have snuffed out the dinosaurs
Tohoku, Japan (UPI) Jul 15, 2016
Because there weren't enough already, scientists in Japan have offered a new theory for how dinosaurs met their demise. Massive amounts of stratospheric soot sprayed skyward by asteroids triggered global cooling, drought and halted marine photosynthesis. The soot worked swiftly to snuff out both dinosaurs and ammonites, a group of ancient ocean mollusks. Researchers arrived at their new theory through a combination of geologic evidence and climate modeling. Chemical analysis sugge ... read more
