Love the Wild: Koala Bears / Marsupials

Fossil Huntress — Palaeo Sommelier

Koala, Phasscolarctos cinereus, are truly adorable marsupials native to Australia. These cuddly "teddy bears" are not bears at all.

Koalas belong to a group of mammals known as marsupials. Fossil remains of Koala-like animals have been found dating back to 25 million years ago. As the climate changed and Australia became drier, ancient vegetation evolved to what we know as eucalyptus, becoming the Koalas food source.

Koalas have pouches on their bellies where their newborns develop. Their wee newborns are called joeys and are born blind and earless. They use their strong sense of touch and smell to guide them instinctively up into their mother's pouch when they are born and live here for about six months.

When they are a little stronger and braver, they get curious, foraging about. They also like to ride on their mother's back until they are about a year old, seeing the world from the safety of Mamma. Adult Koalas love eucalyptus trees and spend their leisurely days eating and napping amongst the foliage.
