Family 

What do we know about dinosaur family life?

In recent decades, we have learned a lot about the "family life" of dinosaurs, especially parental care of eggs and hatchlings. We now know that most dinosaurs probably cared for their young in some way, either simply by creating nests, or by feeding their newly hatched babies much the same way many birds do today. Oryctodromeus, for example, lived in burrows, at least in part, to protect its young. 

Some of the best evidence for parental care was found by famous paleontologist, and former Princeton University student, Jack Horner. In 1978, he discovered a hadrosaurid dinosaur within a nesting ground, as well as other evidence of parental care long after birth and for several generations of offspring. He named this dinosaur Maiasaura, so it a safe to assume that Hadrosaurus foulkii probably exhibited similar behavior.
