Saurophaganax ("lizard-eating master") is a genus of allosaurid dinosaur from the Morrison Formation of Jurassic North America. Some paleontologists consider it to be a species of Allosaurus (A. maximus). Saurophaganax represents a very large (10.9 meters (36 ft) long) Morrison allosaurid characterized by horizontal laminae at the bases of the dorsal neural spines above the transverse processes, and "meat-chopper" chevrons. Much material previously referred to Saurophagus maximus is actually referable to Saurophaganax maximus. The new genus is needed because the original type specimen of Saurophagus maximus is not diagnostic, whereas the material described by Dan Chure is. Note that the type species Saurophaganax maximus is not to be considered conspecific with Saurophagus maximus (which is a nomen dubium), so Saurophaganax is not a renaming of Saurophagus. |

Apatosaurus (: /əˌpætəˈsɔrəs/), also formerly known as Brontosaurus, is a genus of sauropod dinosaur that lived about 150 million years ago, during the Jurassic Period (Kimmeridgian and Tithonian ages). It was one of the largest land animals that ever existed, with an average length of 23 meters (75 ft) and a mass of at least 23 metric tons (25 short tons). The name Apatosaurus means 'deceptive lizard', so-given because the chevron bones were similar to those of a prehistoric marine lizard, Mosasaurus. The name Apatosaurus comes from the Greek ἀπατέλος or ἀπατέλιος meaning 'deceptive' and σαῦρος meaning 'lizard'.
