While listening to the radio, you hear a science report that discusses efforts to protect the nests of sea turtles on the barrier islands of the eastern USA, some of which are endangered species in parts of the world. As you listen to the story, you learn that sea turtle mothers will crawl on to a sandy beach, dig a hole, lay their eggs, bury them, and then return to the sea. This means that the mothers will never see their offspring, having left them to fend for themselves. Moreover, the offspring may never hatch at all because raccoons and feral hogs prey on turtle eggs.

Did dinosaur mothers act like sea turtles, or did they care for their young, not only watching them hatch but staying with them while they grew in their nests? What evidence would be needed to prove dinosaurs took care of their offspring?
