Epoch Eo

Eocene

56.0000 – 33.9000 Ma

The Eocene is a geological epoch that began about 56 million years ago (Ma). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The end point of the Eocene is the Eocene-Oligocene transition (EOT), between 33.9 and 33.4 Ma. Precise boundaries between the epochs are sometimes given at 33.9 or 33.7 Ma.

Scientists have finally confirmed the origin of the mysterious Silverpit Crater beneath the North Sea. New evidence shows that an asteroid about 160 meters wide struck the seabed roughly 43 to 46 million years ago. The impact triggered a tsunami more than 100 meters high and left behind a crater that geologists debated for years.
