Facts for Kids

Maiasaura, meaning "good mother lizard," was a large dinosaur that roamed the earth during the Late Cretaceous period, around 76 million years ago! 🦖

It belonged to a group called duck-billed dinosaurs, or hadrosaurs, which were known for their flat, duck-like snouts. Fossils of Maiasaura have been found in Montana, USA, mainly in a place called the Two Medicine Formation. Maiasaura stood about 9 feet tall and could grow up to 30 feet long, making it one of the largest dinosaurs of its time!

Maiasaura was a very social dinosaur! 🦕

They lived in large herds, which helped protect them from predators. The young Maiasaura were cared for by their mothers, and they may even have helped each other find food. Fossil evidence shows nests where baby Maiasaura lived. This caring behavior gave them their name, as they were excellent mothers, taking care of their little ones like a family!

Maiasaura lived in what is now North America, specifically Montana and parts of Wyoming. 🌍

They liked to hang out in warm, forested areas near rivers and lakes. The environment during the Late Cretaceous was filled with lush plants, allowing Maiasaura to graze on leaves, shrubs, and ferns. They would often gather in herds, making it easier to protect themselves from hungry meat-eaters!

Maiasaura laid eggs in nests to ensure their babies were safe! 🥚

Fossilized nests have been discovered in Montana, filled with eggs and even baby dinosaurs! The mother would create a nest in soft ground, laying several eggs at a time. After the eggs hatched, the mother likely stayed nearby to protect and feed her young. This caring nature helped more babies survive in the wild!

Maiasaura had some interesting features, including a long and broad head, a beak-like mouth, and hundreds of teeth for munching on plants! 🌿

Its body was massive and strong, with sturdy legs that helped it run from predators like velociraptors. Male Maiasaura were usually larger than females. Additionally, they had flat crests on their heads, which may have helped them communicate with each other. This dinosaur had a long tail which helped it balance while walking!

As herbivores, Maiasaura loved to eat plants! 🌱

They had a flat beak that helped them nibble on leaves, and their many teeth made it perfect for chewing tough plants. Maiasaura often grazed in herds, allowing them to find food in their lush habitat. Their diet included ferns, shrubs, and some flowering plants from the Late Cretaceous period. This dinosaur would spend most of its day munching on tasty greens!

Maiasaura fossils were first discovered in 1978 by paleontologist Dr. Jack Horner in Montana. 🦴

Since then, many nests and more than 100 eggs have been found! These finds helped scientists learn a lot about how Maiasaura lived, socialized, and cared for their young. The discovery of Maiasaura changed how people viewed dinosaur parenting, as it showed that dinosaurs could be nurturing!

Maiasaura has appeared in several movies and documentaries! 🎥

It is often featured as a friendly dinosaur and is known for being a good mother. In popular culture, it helps kids learn about dinosaurs and nature, thanks to its caring behavior. Books and toys featuring Maiasaura also help keep this dinosaur alive in children's imaginations. It shows that dinosaurs, like Maiasaura, contributed to our love of the prehistoric world!

Scientists continue to study Maiasaura to learn more about their lives! 📚

They analyze fossils, eggs, and nests to understand how they lived and interacted. Dr. Jack Horner's findings highlighted their nurturing nature and social behavior. Research on Maiasaura has helped scientists understand more about dinosaur evolution and how they adapted to their environment. Every new finding adds to our knowledge of these amazing creatures!
