RE: Giant mammal hair (was Re: DOWNY STEGOSAURS)
AND, let us not forget that OUR nearest relatives are all much hairier than
we & one (the Gorilla) can be considerably larger.
You know, hairiness or furriness is also good insulation against heat. With
many mammals there is an undercoat & moisture dissipation actually helps
cool the animal off.

Subject: Giant mammal hair (was Re: DOWNY STEGOSAURS)
Let's also remember that recently extinct members of at least two
mammal lineages, elephantids and rhinoceratids, were pretty darn
_Mammuthus_ and _Coelodonta_, respectively. And, lest we think that
multi-tonne mammals are strictly mammoth-steppe inhabitants, there
the tropical giant ground sloths to consider.
Out knowledge of the distribution of hairiness vs. hairlessness in
large-bodied mammals is sorely hindered by the fact we are looking
at a VERY
recently depauperate fauna.
