Volcanic Eruptions Triggered Dawn of the Dinosaurs

[Oxytropidoceras]

Volcanic eruptions triggered dawn of the dinosaurs

(Huge pulses of volcanic activity are likely to have

played a key role in triggering the end Triassic mass

extinction, which set the scene for the rise and age

of the dinosaurs, new Oxford University research

has found.)
