The ice age giant beaver may have weighed in at as much as 135 kilograms. The recently unearthed giant beaver jaw bone, top, next to a modern-day beaver jaw shows just how much larger the ancient creature was compared to its present-day relative. (Graham Young/Manitoba Museum)Paleontologists generally believe giant beaver species ranged between 90 to 135 kilograms (200 to 300 pounds), Young said. Scientists believe the last group of giant beaver species went extinct near the end of the last ice age, about 10,000 years ago. "This is such a rare and utterly unique fossil," Young said.
