THE LONG-JAWED MASTODON 



By way of parenthesis I must here mention 

 a mastodon-hke creature of the same age — 

 which had no tusks in the upper jaw, but two 

 huge tusks in the lower jaw, which is bent 

 do^vnward. This is the Dinotherium, found in 

 the Miocene in Germany and other localities. 

 It seems to have left no modern representatives,

 of Mastodon (Tetrabelodon) angustidens from a drawing

and is a sort of extinct side-branch of the ele- 

 phant family. The big tusks of the lower jaw 

 were probably used for raking up roots in the 

 mud of rivers and lakes. 



The Miocene mastodon, with the long lower 

 jaw, is knowm SiS Tetrabelodon angustidens. The 

 examination of its skeleton some years ago led 

 me to the conclusion (as, indeed, was inevitable)
