Re: galloping Paraceratherium

["Ken Kinman" <kinman@hotmail.com>]

     I guess I'll have to start using the rather bland name 
Paraceratherium, which appears to preoccupy the more distinctive name 
Indricotherium  (although I don't have to like it).
     Anyway, it is my understanding that there is little (if any) temporal 
overlap of Paraceratherium with the earlier Andrewsarchus (correct me if I 
am wrong), but I would imagine Andrewsarchus probably ate (scavenged on??) 
some of Paraceratherium's Middle-Late Eocene ancestors.  At least the teeth 
of Andrewsarchus seems to make it more of scavenger than Tyrannosaurus might 
have been.
     Although Andrewsarchus was the biggest known mesonychian, I don't 
think it was the last (as I recall there were some smaller mesonychians 
which survived into the earliest Oligocene, but I can't seem to find their 
generic names tonight).  What is not clear to me is whether there are any 
known specimens of Paraceratherium in the Upper Eocene.  Wish I had a copy 
of McKenna and Bell, 1997, to check on this, but I don't.
