"Pallass's woolly rhinoceros"
Peter Simon Pallass was a German botanist who became a professor at St Petersburg Academy of Sciences in 1768. He led an expedition across the Urals and through Siberia as far as Lake Baikal, the world's largest and oldest (at 25 million years) freshwater lake. Pallass found many animal specimens on his journey, which he took back to St Petersburg.
Yakutia is now known as the Sakha Republic and is located on the north-eastern corner of Siberia.
