High Arctic fossils reveal ancient bear's weakness for sweets
Ellesmere Island fossil site yields bear teeth with cavities and remains of berry plants
An artist’s reconstruction shows Protarctos abstrusus in the Beaver Pond site area during the late summer. An extinct beaver, Dipoides, is shown carrying a tree branch in water. Plants include black crowberry with ripened berries, dwarf birch in foreground, sedges in water margins, and larch trees in background
Two bears living in a boreal forest in Canada's High Arctic millions of years ago munched on too many sweets and didn't brush their teeth, fossil evidence suggests.
As you might imagine, those bears ended up with cavities — something that paleontologists were very excited to see.
