The radius and ulna are very slender straight bones. Of the right 
fore-limb only an impression of the radius is preserved. Of the left the 
proximal portions of both bones are still in the matrix as impressions. 
The ulna is proximally thicker than the radius and has a well-developed 
olecranon process. The length of the radius is 43 mm. 
Of the hand only one digit of the right extremity is preserved. Its 
total length is 28 mm. The metacarpal has a length of 10 mm. There 
are three phalanges. The carpus seems to have been very small. 
Of the pelvis only the distal portion of the right pubis is preserved. 
This is long and very slender, its length as preserved being about 40 mm., 
and its narrowest portion being 3 mm. broad. 
In the right hinder extremity only the distal half of the femur is present 
and in the left only the distal articulation portion. It is a strong bone which 
shows one curve and which may have had another. The length of the 
preserved portion is 56 mm. ; the femur may have been some 10 mm. 
longer. Breadth at the distal end : 10 mm. 
The tibia and fibula are long, straight, and slender bones. In both 
extremities one of the bones covers the other, but in the right leg they 
are still to be seen separately. They are both broad proximally and their 
length is 67 mm. The proximal end of the tibia has a breadth of 6 mm. 
The breadth of both shafts is 3 mm. 
The foot is only represented fragmentarily in the left limb and seen 
from below. There are two large proximal elements in the tarsus and 
there may be four small distal ones. The impression of the astragalus 
is flat and square though slightly longer than broad, the greatest length 
being parallel to the axis of the limb. Its, length is 7 mm. and its breadth 
4,5 mm. The impression of the calcaneum is deep, which might indicate 
that this was a stronger bone than the astragalus. Length 6 mm., breadth 
4 mm. 
Four metatarsals have been preserved. These belong to the first 
four digits and are all nearly equally long. The third and fourth have 
nearly the same length. The second is just slightly shorter than the third 
and the first is slightly shorter than the second. Their lengths are : First 
26 mm., second 28 mm., third 28,5 mm., fourth 28 mm. The first digit 
shows two phalanges, but the other three only show the proximal ends 
of the first. The first phalange has a length of 8,5 mm. and the second 
a length of 5 mm. The proximal breadth of the third metatarsal is 3,5 mm. 
The distal breadth of the first and fourth is 3,5 mm. and of the second and 
third 4 mm. 
Dermal ossifications are present all along the back from the skull 
till far down the tail. There is also a dermal covering on the ventral side 
of the body. The dorsal ossifications are arranged in two rows, one row 
on each side of the dorsal spines with which they are in touch. These 
scutes have a rectangular shape and are mostly 10 mm. square. Some 
scutes of the tail which are not so well preserved as the others, are slightly 
shorter than broad. Those at the tail end are smaller than those of the 
body and each pair seems to associate with a vertebra. In view of this 
fact we might assume that there had at least been 22 presacral vertebrae.
