THE POSE OF SAUROPODOUS DINOSAURS' 



These four articles discuss a question of considerable 

 general interest. Did the huge Sauropodous dinosaurs. 

 Diplodocus, B rout ostiums and their allies, walk like ele- 

 phants, or crawl like crocodiles The skeletons and casts 

 in the larger museums of America and Europe have all 

 been mounted straight limbed, with the body well clear of 

 the ground. But the evidence for giving them this pose, 

 so different from that of the generality of reptiles, 

 although well known to those who are responsible for it, 

 has not until recently been published. Hence it is not 

 surprising that these reconstructions have been criticized 

 more or less seriously, especially in Germany, and that 

 two writers of high scientific standing — Dr. Tornier in 

 Berlin, and Dr. Hay in Washington— have contended that 

 these animals could not have walked upright, but must 

 have dragged the belly on the ground as crocodiles and 

 lizards normally do. Both writers have attempted and 

 discussed at length the re-articulation of the skeleton in 

 the crocodilian pose. 



Dr. Tornier 's argument is. brie-fly, that reptiles crawl
