"dinosaur's age"?  Is there anything out there about how long dinosaur's 
lived?

As far as I am aware the lamellar bone forms rings that are thought to have 
been annual, although it is possible that they mean something totally 
different.  One bone that I have sectioned suggests the dinosaur was 
something between 30 and 40 years old before it died (using the above 
assumption).  Other estimates for some dinosaurs are as much as 100 years.
