The researchers went back to the island in 2010 and 2012 to collect more shark teeth. They estimate that the teeth date to the late-early or middle Eocene epoch, or about 53 to 38 million years ...

Climate Models of Earth’s Hottest Period Offer Frightening Glimpse Into Future. An examination of Earth’s climate 50 million years ago could lead to some significant ... -of-the-art climate prediction ...

The Eocene (symbol EO) Epoch, lasting from about 56 to 34 million years ago (55.8±0.2 to 33.9±0.1 Ma), is a major division of the geologic timescale and the second epoch of the Paleogene Period ...

Researchers report revised estimates of sea surface temperatures (SSTs) during the Eocene epoch, 56-34 million years ago, which suggest that the tropical oceans registered at 30-36 °C ...
