In the Dinosaur Data Book, David Lambert wrote:

   "How long a dinosaur could live is quesswork. Growth rings in certain
bones and teeth suggest at least 120 years. If dinosaurs were
warm-blooded, big sauropods might have reached that age; if cold-blooded,
200 years or more. But injury o disease killed most before extreme old
age.."
