Summary

The notion of mothering dinosaurs has taken off since paleontologists argued that hatchlings seemed weak in the knees. Unable to walk very well, hatchling survival would depend on doting parents bringing back food, like mother pelicans regurgitating food for their young. But on (p page 712)of this issue, paleobiologists present data on baby dinosaur pelves and leg joints that suggest the creatures hit the ground running—the bones were robust at birth, implying self-sufficient creatures that didn't need hovering parents. Attacks on motherhood usually stir up controversy, however, and this one is no exception.
