Like other land animals, some dinosaurs, like the baryonyx, may have been able to swim if they found themselves in water, but there is no conclusive scientific evidence to support this.

    Why was the brontosaurus's name changed to the apatosaurus?

    A:

    What are the two classes of dinosaurs?

    A:

    Beginning in 1887, dinosaurs have been divided into two main categories: saurischian, which means "lizard hipped," and ornithischian, which means "bird hipped." This classification is based on the dinosaurs' pelvic bone structure. Though the name "bird hipped" may seem to indicate that these prehistoric animals are related to birds, that is not necessarily the case.
