* Scientists Discover How Some Dinosaurs Grew So Big *
(https://learningenglish.voanews.com/a/scientists-discover-how-some-dinosaurs-grew-so-big/5684658.html)
Scientists studying the remains of ancient creatures say that large dinosaurs did not grow at the same rate. Some dinosaurs grew slowly and steadily. Others experienced a growth spurt as they neared adulthood. A “growth spurt” is when something or someone grows very quickly. For example, children usually have a growth spurt between the ages of 12 and 18. The same appears to be true for some dinosaurs! The research appeared recently in the Proceedings of the Royal Society B publication. To reach their findings, scientists cut through the fossilized bones of dinosaurs. They examined the yearly growth rings of the bones from 11 kinds of theropods. Theropods are a group of dinosaurs that mainly walked on two legs and include big meat-eating dinosaurs, like tyrannosaurus rex, commonly known as T. rex. Reuters news agency reports that this new study provides a look into the lives of some of the most fearsome hunters ever to walk the Earth.
