Who Looks After the Kids
Description
A data set with Clutch Volume (cubic milimeters) and adult Body Mass (kg) in six different groups of animals: modern maternal-care bird species (Mat), modern paternal-care bird species (Pat), modern biparental-care bird species (BiPI), modern maternal-care crocodiles (Croc), non-avian maniraptoran dinosaurs thought to be ancestors of modern birds (Mani), and other non-avian dinosaurs (Othr). The question of interest was which group of modern creatures most closely matches the relationship in the maniraptoran dinosaurs.
