Baby dinosaur bones are giving scientists new understanding of a species that lived 67 million years ago.
The rare find was led by Kristi Curry Rogers of St. Paul's Macalester College. It was published this week in the journal Science.
The bones come from a baby titanosaur, or Rapetosaurus. They were huge dinosaurs that grew to over 50 feet long.
After studying the baby bones, scientists discovered that this dinosaur's bones grow isometrically, which indicates that the species didn't need much parental care when young.
For some scale, the baby's shin bone was about as long as a pencil. An adult's shin bone would've been about five feet long.
Curry Rogers joined All Things Considered host Tom Crann to discuss the findings.
