Subject: [meteorite-list] Volcanoes, Not Impacts, Caused End Triassic Mass Extinction

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.)

Crystals once deep inside a volcano offer new view of magma, eruption timing (Volcanologists are gaining a better understanding of what?s going on inside the magma reservoir that lies below New Zealand?s Mount Tarawera volcano. They?re finding a colder, more solid place than they thought, according to research published today in the journal Science.)
