A dinosaur which they have examined was apparently able to vary the speed of its growth according the conditions obtaining in its environment. Although tortoises and crocodiles also do this, plateosaurus engelhardti seems to be unique among dinosaurs, leading experts to puzzle over whether the family history of the dinosaurs will need to be rewritten....

In a paper published in the June 3 issue of the journal Science, Dr. Mary...
