The "good mother reptile" was described in 1979 by Dr. Jack Horner (Jurassic Park films consultant). This dinosaur brought new concepts that are in place today on the parenting habits of dinosaurs.
It was 9 meters (29.5ft), 3 meters (10ft) in height at the hips and 3 tons in weight. Maiasaura lived during the Late Cretaceous about 80 to 72 million years ago.
This species is in question since Maiasaura only appears on a Field Guide trading card in the Jurassic Park 3 set of trading cards, card #67.
