This book explores research about whether dinosaurs cared for their young. It looks at reptiles who mostly abandon their eggs, excluding crocodiles, and then examines dinosaur fossil records. The maiasaurus, a type of duckbill dinosaur, appeared to care for their young because juvenile dinosaurs stayed at the nest after hatching with adults. The book also talks a little bit about how duckbills lived. The illustrations are all black and white but nicely done. ( )
