I'd've Called it the "Lesser Litvak's Beaver-Otter"

Paleontologists in that dusty part of China where all the fossils hang out have discovered a fossil of the earliest known swimming mammal. 
164 million years of swimming mammals.
Looking like a miniature (1-2 lbs.) cross between a beaver and an otter, they named it the "Otver."  Well, actually, Castorcauda lustrasimilis, which amounts to the same thing.
My question is, I guess, did it really have a fin?:
