Elpistostege watsoni was a tetrapod-like fish from the Devonian that lived more than 380-million-years ago.

The fossil was found in Quebec, Canada, and shows fin bones in an arrangement very like more advanced tetrapods. It's the earliest known well-developed hand-like structure.

A new geologic age has been formally named and accepted.
At a recent meeting of the International Union of Geological Sciences, geophysicists officially named the time between 770,000 and 126,000 years ago the Chibanian Age. If falls squarely in the Pleistocene, and was named after Chiba Prefecture in Japan where the strata were initially studied.
 
The Pleistocene is now divided into four Ages.
 
  • Late Pleistocene, sometimes called 'Tarantian', starting 126,000 years ago.
  • Chibanian, starting 770,000 years ago.
  • Calabrian, starting 1,800,000 years ago.
  • Gelasian, starting 2,580,000 years ago.
