Herbivorous Dinosaur Coprolites

Was wondering if anyone saw the article in the June issue of Palaois
regarding the work of Karen Chin (University of California, Santa Barbara)
and Bruce Gill (Agriculture Canda, Ottawa)?  They have been studying the
coprolites of Cretaceous herbivores.  Most notable of their findings are
tunnels in the coprolites that they attribute to dung eating beetles.  If
this interpretation is true, it significantly revises the evolutionary
position of such beetles.  It has been generally accepted that they arose
with mammalian herbivores well after the dinosaur extinctions.

I would be interested in any of your coments.

Best regards .... Michael
