Study Examines Dinosaur Growth Spurts

T. REX HAD A TEENAGE GROWTH SPURT, BUT NOT ALL DINOS DID

(CNN) – Paleontologists are using analyzation used on trees to study dinosaur bones to bring new insights on how they grew and aged.

It turns out like tree trunks, dinosaur bones have rings that tell scientists a great deal about how fast they grew and how long they lived.

For instance, the predator Tyrannosaurus Rex grew very quickly, gaining more than 35 lbs. a week.

A new study published tuesday in the proceedings of the royal society examined the bones of 11 different dinosaurs.

While T.Rex showed a growth spurt, some of the giant creatures grew very slowly and lived a comparatively long time.

The recently identified Carcharodontosaurus lived as long as 50 years, and only stopped growing in its late forties.

The authors were surprised to see such variety in the different species, that some dinosaurs grew quickly and others took their time to mature.
