Welcome to CoreFacts, where we're always short on time and big on science. I'm Brian Campbell. Today's question is ...

Were dinosaurs social animals?

Some dinosaurs were social creatures. Recently discovered evidence indicates that they traveled together and that some may even have migrated (because dinosaur fossils have been found above the Arctic Circle, where food supply would have been seasonal). Grouped hadrosaur nest sites have been found with badly crushed eggshells and skeletons of baby dinosaurs (with slightly worn teeth) still in the nests, suggesting that some babies stayed in their nests after hatching and probably were fed by parents.

And now you know.  Join us again every week for a new CoreFact.  For other CoreFacts, or for CoreCast, our in-depth science podcast, go to usgs.gov/podcasts.  If you'd like to have a question featured on our show, give us an e-mail at corefacts@usgs.gov or a phone call at 703-648-5600.  Remember, long distance fees do apply.  CoreFacts is a product of the U.S. Geological Survey, Department of the Interior.
