Rodent Fossils

This is a large aquatic rodent similar to a huge muskrat which still exists in South America. They are somewhat similar to a beaver and are occasionally found as fossils in Florida.
This was a truly formidable beast which weighed around 500 pounds and reached a length of eight feet. Some of the huge upper incisors measured 10 1/2 inches in length (although a good portion of this length extended into the skull and was not visible). The particular animal for which this species was first named was found in Ohio, hence it is called Ohioensis. Except for their great size, the giant beavers were almost identical to the modern beavers of today. The upper incisors were much more curved than the lowers. This is also true of tapir canines.
