'Sasha': Photos of an Extinct Woolly Rhino Baby

A hunter and businessman stumbled across a rare find in a frozen riverbank in Siberia: The remarkably complete remains of a baby woolly rhino. Nicknamed Sasha, after its discoverer, the specimen is one of just a handful of its species that have been found since the 18th century, researchers say. The creature was donated to the Yakutian Academy of Sciences in Russia, where scientists are trying to extract its DNA in order to place it in a family tree of its closest relatives. Here are some photos of the rhino, where it was found, and the team that is studying it. [Read full story about the baby woolly rhino]

Sasha's body

The frozen woolly rhino calf is about 1.5 meters long (4.9 feet) and 0.8 meters high (2.6 feet), researchers said. Woolly rhinoceroses (Coelodonta antiquitatis) lived in Eurasia during the Pleistocene epoch, which lasted from 2.59 million to 11,700 years ago. (Image Credit: Yakutian Academy of Sciences)

Sasha's head

Sasha's feet

Researchers don't know whether the calf was a male or a female, but it was probably between three and four years old when it died. (Image Credit: Alexander Benderov)
