Eucastor Explained

Eucastor is an extinct genus of beaver-grouped rodents.^{[1] [2]}

Based on the available evidence of the foramina, Eucastor most likely is closely related to Castor, but not in its direct lineage.^[3]

It has two species, the type Eucastor (formerlly Castor) tortus, and E. malheurensis^[4]
