That which is still present of the calcaneum is triangular. The edge which 
is turned towards the astragalus has a length of 10 mm. The front edge has 
the same length and is slightly concave. The lateral angle seems to be more 
pointed than the two inner ones. 
The distal tarsalia probably also show their upper surface. The cuboid is 
the largest of the three. Its length is 15 mm. and the breadth of that of the 
left foot is 10 mm. It has a triangular shape and the line of what may be its 
hinder surface is convex and forms the longest side of the triangle. In the 
right foot it turns its sharpest angle outwards, but in the left inwards; how- 
ever, in the left foot the tarsalia seem to be displaced (see fig. 6). Cunei- 
forme III and II are both too deep in the matrix to say anything about them 
with certainty. 
Foot. 
Both feet are preserved. All the bones are flattened, although the right 
foot is slightly better in this respect than the left one. An impression with 
part of the bone of the left foot is present in both slabs. 
Metatarsal I is not visible in the right foot; the left one has a length of 
38 mm. and distally a breadth 6f 14 mm. Its proximal end seems to be narrow. 
The lateral side of the distal end of the flattened bone is broad and rounded, 
while its medial side forms an angle at a short distance from the extreme 
distal end. This corresponds, therefore, with a large rounded lateral head and 
a small medial one as described by v. Huene for example in Plateosaurus 
Reinigeri ( 3 , p. 28). As in that species, the axis of the articulation surface for 
the first phalanx would, therefore, not be at right angles to the axis of the 
metatarsal, but turned slightly inwards. This is actually the case, for the 
distal end of the first phalanx stands off inwards.* 
Metatarsal II has a length of 59 mm. Its proximal end is cut off straight. 
The lateral side of this end is hollow and forms a sharp ridge with the flat 
hinder surface. The medial side is not visible, but is probably also hollow to 
receive the proximal end of metatarsal I, which partly covers it. The length 
of the hinder border of the proximal surface is about 10 mm. The shaft is 
straight and has a width of 9 mm. at its narrowest part. The distal end is 
also cut off straight. It cannot be made out whether the axis of the distal 
articulation surface was at right angles to the axis of the bone or not. Pro- 
bably, however, its medial end was slighty higher than its lateral one, for the 
axis of the first phalanx deviates slightly inwards from the direction of the 
axis of metatarsal II. The distal end has a breadth of about 15 mm. 
Metatarsal III has a length of 66 mm. It is more slender than metatarsal II. 
Its proximal end has a breadth of 17 mm. and shows on its hinder surface a 
slight longitudinal ridge, possibly marking the extent to which it covered 
metatarsal IV. The shaft is straight and measures at its narrowest part 9 mm. 
Near the distal end the medial side of the shaft is concave and the lateral 
side convex. The breadth of the distal end is 14 mm. The axis of the distal 
articulation surface is not at right angles to the axis of the bone, as its medial 
end is slightly higher than its lateral one. 
Metatarsal IV has a length of 60 mm. It is a much more slender bone 
than metatarsal III. The breadth of its distal end is 12 mm. The distal arti- 
culation surface is not at right angles to the axis of the bone. Its lateral end 
is higher than its medial end. It rounds off gradually into the lateral side of 
the bone. The impression of its dorsal surface shows a broken off knob of 
matrix, which entered into the lateral collateral pit. 
Metatarsal V has a length of 30 mm. Its proximal end is broad and its
