Did Dinosaurs Raise and Look After Their Young Ones?

It took scientists a long time to figure out how dinosaurs raised their young. It was only in the 1920s that researchers discovered that dinosaurs actually laid eggs and did not give birth like animals did.

Different dinosaurs had different parenting styles. Although we don’t know everything about these practices, there is enough evidence to show that most dinosaur eggs were hatched from young ones that could run and walk. A dinosaur will usually lay around 20 to 30 eggs but this number will vary depending on the species. The reason for laying so many eggs boils down to the theory of survival of the fittest. Many babies are eaten by predators at birth, and only a few survive to adulthood.

For many years scientists believed that dinosaurs actually laid their eggs and then forgot them, leaving the baby dinosaurs to fend for themselves. However, in the 1970s, a nesting ground of a duck-billed dinosaur named Maisaura was found in Montana by paleontologist Jack Horner. In this nesting ground, researchers found not only fossilized eggs but fossils of new babies, young dinosaurs and adults.

A careful examination of the fossils shows that young Maisaura did not have fully developed leg muscles and therefore, was unable to walk and run. Additionally, the teeth of baby dinosaurs show wear and tear. This led scientists to conclude that the older Maisauras actually brought food back to the nest so that the young dinosaurs could eat until they were old enough to take care of themselves. A similar site is found in China for Psittacosaurs.

However, it would be wrong to say that all plants take care of young people. For example, based on some evidence, scientists have concluded that sauropods did not take care of their young. A newborn Apatosaurus would have been about 12 inches long and could easily be crushed under its own mother’s feet. Therefore, the survival rate of Apatosaurus will be higher if it feels like moving on its own.

Scientists are still trying to find out more about the birth and mothering habits of the Tyrannosaurus Rex because nothing is known about its parenting habits.
