  Recovery is more interesting than extinction, but not as exciting or
Timely.

I disagree that understanding the recovery from extinction is less exciting
or timely than understanding extinction dynamics.  In the case of the F/F
event, echinoderms were devastated along with many other groups. 
Regardless whether the extinction event was sudden, prolonged, stepped or
pulsed, stemmed  echinoderms again flourished in the Carboniferous. In this
case and many others, understanding the dynamics of rebound and
rediversification is both timely and exciting. The recent IGCP 335  meeting
(Biotic Recovery from Mass Extinction Events" in Plymouth provided plenty
of examples within thid context. Johnny Waters
