upper half of the bone, and whose anterior surface is inclined to 

 the axis of the bone, the upper half pointing medially, the lower 

 end outwards. The lower end of this crest at its junction with the 

 shaft lies half-way down the huinerus. 



The distal end is broad, but the condyles are not greatly thickened, 

 the whole articular surface being much narrower in comparison

with its length than in the European species of Plateosaurus or in 

 Pachysaurus. Both condyles are somewhat thickened in front, 

 but practically not at all on the posterior face. On the anterior 

 surface there is a marked concavity above the condyles in the 

 median line. 



The following table gives the chief measurements of the two bones 

 and compares them with those of the huinerus of Plateosaurus 

 reinigeri :
