There’s not a clear winner in the contest for best dinosaur mother. But the Maiasaura is not the only dinosaur that cared for its young.
The Allosaurus is another dinosaur known for its quality parenting skills. In Portugal, an Allosaurus nest was discovered along with the remains of 20 eggs. Crocodile eggs were discovered in the same area as the Allosaurus eggs. Paleontologists determined that the crocodile likely laid her eggs there because she knew the Allosaurus mother would fiercely protect her eggs (and the area) from predators. Clever!
The Oviraptor is another example of a good dinosaur parent. Paleontologists came to this conclusion based on a discovery in Asia. They discovered the remains of an oviraptor actually sitting on its eggs. No wonder the remains are known as Big Mama!
