Edward Everett would speak from that stand later in the afternoon for two straight hours. Moments later, a tall, gaunt Abraham Lincoln would stand up and deliver a ten sentence speech in two minutes. It was the Gettysburg Address.

The Neoproterozoic Era is the unit of geologic time from 1 billion to 538.8 million years ago. It is the last era of the Precambrian Supereon and the Proterozoic Eon; it is subdivided into the Tonian, Cryogenian, and Ediacaran periods. It is preceded by the Mesoproterozoic Era and succeeded by the Paleozoic Era of the Phanerozoic Eon.
