166 DINOCERATA. 



The animal is represented as walking, and the position of the head, 

 and the feet, has been chosen to show, to the best advantage, these 

 jDortions of tlie skeleton as they were in life. In this restoration, only 

 those portions are shaded which are represented 1)}' actual specimens in 

 the Yale Museum. Tlie parts in outline are either wanting, or so poorly 

 preserved that only their main features can be given with accuracy. 



In the restoi-ation of Tinoceras inf/ens, Plate LVI, the animal is 

 represented one-sixth natural size, and standing at rest. The position 

 here chosen shows the massive and majestic form of one of the largest 

 individuals of this remarkable group. Here, likewise, the shaded portions 

 are represented by specimens in the Yale Museum. Some of these bones 

 were used also in the first restoration. 



In comparing Dinoceras, as here restored, with some of the largest 

 ungulate mammals of the present day, a certain resemblance to the 

 rhinoceros on the one hand, and to the elepliaut on the other, will 

 naturally suggest itself In size and proportions, Dinoceras was 

 intermediate between these two existing animals, and in various points of 

 its structure, it resembled the one quite as much as the other. In still 

 other features, Dinoceras resembled the hippopotamus, and its affinities 

 with the groups represented by these three types will be discussed in 

 the succeeding chapter. 



In its stature and movements, Dinoceras probably resembled the 

 elephant as much as any other existing form. Its remarkable skull, 

 longer neck, and more bent fore limbs, gave it, however, a very different 

 appearance fi-om any knowm Proboscidian. The high protuberances on 

 the head, the long trenchant canine tusks, and the peculiar lower jaw 

 modified for their protection, are features seen together only in this group. 



The neck was long enough to permit the head to reach the ground, 

 and hence a proboscis was quite unnecessary. The horizontal narial 

 opening, the long overhanging nasal bones, and the well developed 

 turbinal bones, are likewise proof positive against the presence of such 

 an organ. There is some evidence of a thick flexible lip, resembling, 

 perhaps, that of tlie existing rhinoceros.
