- Franklin D. Roosevelt (allthetropes.org)
Franklin Delano Roosevelt (1882-1945) was the longest serving President in US History, serving three full terms and starting his fourth when he died. No other President had even won a third term (a couple had tried — Grant and T.R. — but none were elected). And, thanks to the 22nd Amendment, no President since will be able to challenge his length of service (barring the very unlikely event of the 22nd being repealed).
- Pliocene (Wikipedia)
The Pliocene ( /ˈplaɪ.əsiːn, ˈplaɪ.oʊ-/ PLY-ə-seen, PLY-oh-; also Pleiocene) is the epoch in the geologic time scale that extends from 5.333 million to 2.58 million years ago. It is the second and most recent epoch of the Neogene Period in the Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.588 to 1.806 million years ago, and is now included in the Pleistocene.
