I don't really know what the purpose of the following study actually was, but some paleontologists have unraveled that dinosaur males were good fathers, guarding the nest and looking out for the kids. This conclusion is drawn from the analysis of clutch sizes, where the volume of these were two/three times larger than expected from adult body size and the largest clutch sizes ought to have been cared for by males only. Now that's something to tell your chauvinist boss if he derides you for wanting to stay at home for a while with your newborn.
