The Good Momnn“Mom’s” the word when Mrs. Pteranodon meets fellow mom Millie Maiasaura, who is a little too over-protective of her kids. The two moms compare mothering methods in a play date at the Big Pond.nnFun Fact: Maiasaura, meaning “good mother lizard,” was a large duck-billed dinosaur that lived in North America during the Late Cretaceous. There is evidence that Maisaura lived in large nesting colonies and that the parents diligently cared for their young.nnHornucopia!nnAt the Big Pond, Tank introduces the Pteranodon family to his friend, Stacie Styracosaurus, a fellow Ceratopsian with a crown of elaborate horns on her head. Everyone attends Stacie’s “Hornucopia” celebration, where she reveals her new big horns and then performs a moonlit shadow show with her Styracosaurus family.nnFun Fact: Animals use lots of different features for display, or “showing off,” but within a group, these variations tend to focus on the same kinds of features. The species called Ceratopsians (horned dinosaurs) include Styracosaurus, a creature with elaborate horns and frills that they employed to show-off to other dinosaurs.
