CRETACEOUS DINOSAURS 209 



The researches of Woodward have extended the recorded geographic 

 range of dinosaurs to the eastward as far as New South Wales, but of 

 this specimen the precise horizon, other than the fact of its being Cre- 

 taceous, is not announced. 



Of the Cretaceous Theropoda the most interesting recent material has 

 been obtained by the American Museum, where there will be shown 

 anatomically complete restorations of ^ojne of the most majestic of the 

 group. ^ 



Sauropoda 



In North America the sauropodan career almost ceases with the re- 

 markable host of Morrison forms, for in the Cretaceous beds representa- 

 tives of this group are extremely rare, but two instances being known to 

 me, both announced within the last ten years. Of these specimens one 

 is mentioned by Gilmore as coming from the Lakota of Buffalo Gap, 

 South Dakota ; Gilmore does not, however, identify the remains gener- 

 ically. The other is from an apparently equivalent level, the Trinity 

 sands of Oklahoma, and is identified as Morosaurus. These relics, occur- 

 ring as they do in a horizon immediately overlying the Morrison, are 

 apparently two of the few remaining representatives of the sauropodan 

 fauna after its general extinction in North America. In Europe, so 

 far as our records now show, this story is practical^ repeated, for aside 

 from two Aptian localities in France and Portugal, the Cretaceous 

 record above the Wealden is again a blank. Deperet described from 

 Languedoc, France, in beds of Danian age, a supposed sauropod which 

 he called Titanosaurus, and which, if the identification were correct, 

 would indicate a lingering on of these forms in Europe long after their 

 extinction in the New World. Nopcsa, however, has since declared 

 (1910) that this reptile "has nothing to do with the Sauropoda, but 

 belongs to the Trachodont Orthopods." This effectually disposes of 

 what was to me a great quandary at the time of the publication of my 

 paper on dinosaur distribution, in January, 1910, and seems to prove 

 that the extinction of the Sauropoda in the entire northern hemisphere 

 was practically simultaneous. 



On the other hand, Cretaceous sauropods are reported from Africa, 

 Madagascar, and India of apparently Cenomanian age, and from Pata- 

 gonia, where they are found in the Guaranitic beds, which represent the 

 deposition of the very close of the Cretaceous period. 



A notable new Cretaceous locality is at Tendaguru, five days' march 

 from Lindi, on the coast of German East Africa, in beds considered by 

 Fraas to be Upper Cretaceous, but which eventually may be shown to
