Fig. This is an elusive animal and is rarely seen, but it's the largest species of shrew in the UK and can grow up to 10cm in length. Their ancestors, mainly found in Eurasia, date to about five million years ago.Dr Wang said fossil records of ursine bears - all living bears plus their ancestors, except the giant panda, which is an early offshoot - are poor and their early evolution controversial.The new fossil represents one of the early immigrations from Asia to North America, but it is probably not a direct ancestor to the modern American black bear.The bones were discovered over a 20-year period by Canadian Museum of Nature scientists at a fossil location known as the Beaver Pond site, which fossil records show was home to a variety of creatures (artist's impression)Dr Wang said that it is also significant that the teeth of both Protarctos individuals show signs of 'well-developed' dental cavities, which were identified following CT scans.Dr Wang added: 'The cavities underline that these ancient bears consumed large amounts of sugary foods such as berries.

'The research team were able to study recovered bones from the skull, jaws and teeth, as well as parts of the skeleton from two individuals.The bones were discovered over a 20-year period by Canadian Museum of Nature scientists at a fossil locality on Ellesmere Island, known as the Beaver Pond site.The peat deposits include fossilized plants indicative of a boreal-type wetland forest, and have yielded other fossils, including fish, beaver, small carnivores, deerlets, and a three-toed horse.Study co-author Dr Natalia Rybczynski, said: 'It is a significant find, in part because all other ancient fossil ursine bears, and even some modern bear species like the sloth bear and sun bear, are associated with lower-latitude, milder habitats.The findings show that the Ellesmere Protarctos (artist's impression) lived in a northern forest habitat, where there would have been 24-hour darkness in winter, as well as about six months of ice and snow'So, the Ellesmere bear is important because it suggests that the capacity to exploit the harshest, most northern forests on the planet is not an innovation of modern grizzlies and black bears, but may have characterised the ursine lineage from its beginning.
