Temporal range: Late Cretaceous
Maiasaura lived about 80 to 65 million years ago in the late Cretaceous period. It was described as a kind and good natured dinosaur who ate plants, leaves and berries. It ate no meat at all since it was a herbivore. Its name Maiasaura means “Good Mother Lizard”. It was named this because scientists discovered that it looked after its young. Maiasaura measured about 9 metres long, 2-2.5 metres tall and weighed around 1800 kg.
