Not Lost

For the most part kids never actually lost Brontosaurus. Many of the sources for dinosaur information still listed Brontosaurus as a valid name or, at the very most listed it in parentheses as Apatosaurus (Brontosaurus). That is why the majority of sites that we can reference today mention or are titled Apatosaurus (with the exception of the misspelled "Apotosaurus" of KidsDigDinos). The New Zealand hosted Science Kids hosts a good encyclopedia style page and Animals for kids parallels and maybe even outdoes this. The black and white search of images turns up a plethora of coloring sheets that can be used to make your own thunder lizard.
