The New Pre-Cambrian Period
Scientists have recently had to name the period that predates the Cambrian Explosion because they've been finding so many new, simpler fossils of that age, the Ediacaran:
It's also providing heaps of controversial organisms and likely decades of new research material: very exciting.
The rules of English pronunciation are giving me a problem with "Ediacaran," though. Can someone from Australia help? My best guess would be "ee-dee-uh-KAIR-en," or possibly "eh-dee-ACK-er-en."
