length of the bone as preserved is 26-5 cm. The breadth of the proximal end, 
measured from the medial end of the caput femoris to the lateral side, is 
15-5 cm. Its maximum thickness, measured 
medially to the trochanter minor, is 9 cm. The 
caput femoris is directed inwards; it has a 
breadth of 8-5 cm. and a height of 8-5 cm. 
The proximal surface is convex, rough and 
pitted, and forms an angle with the lateral 
side. The trochanter minor lies on the hinder 
surface and very near to the border of the 
proximal surface. It is a thick broad boss, 
the middle of which is situated at 8-5 cm. 
from the medial end of the caput femoris and 
at 6*5 cm. from the lateral side of the bone; in 
this therefore it differs from the trochanter minor of most Plateosauridae y 
which is there situated much nearer to the medial than to the lateral side. 
The height of the trochanter minor is 1 cm., 
its length is about 6 cm. and its breadth about 
5 cm - 
The upper end of the trochanter major is 
situated at a distance of 12 cm. from the 
proximal end of the bone. The ridge of the 
trochanter is worn away, but it is still plainly 
visible that its lateral side formed a deep, 
broad groove with the general surface of the 
bone. The height of the trochanter near its 
proximal end as preserved is 2*5 cm.; it may 
originally have been 1 cm. higher. The length 
of the trochanter is about 10 cm. The femur is broader and thinner 
between its proximal end and the trochanter major than further downwards. 
A broad thick ridge runs from the trochanter major downwards apparently 
in the direction of the condylus medialis. This ridge continues upwards from 
the trochanter, but diminishes gradually in height and loses itself at about 
midway between the trochanter and the proximal end of the bone. The ridge 
is concave on its medial side opposite the trochanter major. The trochanter 
does not lie on the top of the ridge, but is situated on its lateral side. The 
medial side of the anterior surface of the bone is concave as far as preserved. 
The lateral side of the anterior surface, below the trochanter major, is convex. 
The medial side of the proximal end of the bone is concave, while its lateral 
side is slightly convex. Therefore, the upper end of the bone is turned slightly 
inwards. The hinder surface of the proximal end was originally flat; now it 
is irregularly concave through pressure. Opposite the trochanter quartus it 
rounds off, over the lateral side, into the anterior surface. Higher up, the 
lateral side is flatter and its borders with the anterior and posterior surfaces, 
are more conspicuous. 
The trochanter quartus begins at a distance of 17-5 cm. from the proximal 
end of the bone. Only a small portion of the trochanter is present; the lower 
half of the trochanter and the whole of its upper edge are lost. The portion 
preserved has a maximum height of 4 cm. Its breadth at the base, just above 
the fracture, is about 5-5 cm. The medial side of the trochanter is concave 
and the lateral side convex. Nothing is visible of a second upper ridge, but 
this may be due to crushing. The trochanter is situated nearer to the medial 
than to the lateral side of the bone. The breadth of the diaphysis over the
