Dino Knows Best

* When most people think of dinosaurs, they think of fierce, meat-eating T. rexes or long-necked, plant-eating brachiosaurs. They don't necessarily think: loving mom and dad.

But a new study says that at least some dinosaurs may have cared for their young for a long period of time.

Researchers have come to this conclusion because of a recent discovery in China. Scientists unearthed an adult Psittacosaurus surrounded by 34 young dinosaurs. The young animals (not babies) were all in a five-foot space. Scientists think all the animals died at the same time, because of a volcano eruption, a flood or the collapse of an underground cave.

Crocodiles and birds care for their young. And since those animals are distant relatives of the dinosaurs, scientists have long wondered about dinos as parents.

A Peek at Potter 6

* J.K. Rowling is still working on "Harry Potter and the Half Blood Prince," the sixth book in the wizard series. But the author is sharing two sentences from the book:

"He looked rather like an old lion. There were streaks of grey in his mane of tawny hair and his bushy eyebrows; he had keen yellowish eyes behind a pair of wire-rimmed spectacles and a certain rangy, loping grace even though he walked with a slight limp."

No word yet on when the book will be out.
