Sardolutra ichnusae is an extinct species of otter from the late of Sardinia. It was originally described as Nesolutra ichnusae. It was a rather small species of otter, probably living in the sea. Among its characteristics is a relatively very large baculum, larger than in any living otter. The species probably evolved from a species of Lutra, maybe L. castiglionis.
