+++++++++++++++++++++++++++++++++++++++++++++++++++

To heck with the growth rate, if the 50 year limit
applies to all the large sauropods, then that makes
for a remarkably craptacular lifespan. 

Even (relatively) puny elephants beat that number out
at 70 years.

Which says nothing for bicentennial whales.
