Thalassocnus...the naked sloth?

[Brian Lauret <zthemanvirus@hotmail.com>]

I'm allmost sure most people on this list have heard about the Thalassocnus 
species series. These nothrotheriid xenarthrans evolved from terrestrial 
herbivores into (semi-)marine seacow-lookalikes,complete with the broad 
snouts.

Now I wonder, would this convergence have gone as far as these fascinating 
critters being hairless like a seacow? I wonder especially about the later 
species as I'm quite sure the most basal ones were still hairy.

I do not know wether I find the idea of a naked ground sloth very pleasant 
though..
