Re: really big question



The Solenhofen matrix is micrite, correct?
It wouldn't hurt to plant a bunch of bird carcasses (of different species
with different feather patterns) on a carbonate mud floor of a modern
warm water lagoon and chart their decay over time.  A carbonate mud will
harbor a vastly different microbiota than will a phylosilicate mud.  And
a warm benthic envirnment is much different than a cold benthic
environment

If the study hasn't been done yet, it would make a neat M.S. thesis for
someone who likes to SCUBA dive in tropical seas, and who doesn't mind
handling rotten birds.
