Product Description

Castoroides ohioensis is generally described as a “beaver the size of a bear.” This large animal lived in many parts of North America during the Ice Age, and became extinct about 10,000 years ago. This particular fossil was discovered in a gravel pit in southeast Manitoba in 2017, and was recently donated to the Museum. The age of this specimen is possibly in the range of 50,000 years old, based on analysis of fossil wood from the same area. When compared to the jaw of a modern-day beaver, its size, and in particular the massive incisor at almost 17 cm, is very impressive. This near perfect specimen is the first of its kind ever found in the Prairie Provinces!
