DESCRIPTION
The lower canine (UM VD46), of which part of the root and part of the crown are broken off (
Fig.5D
), displays the large size and crenulated trenchant distal carena that is typical of a large sabre-toothed cat.
Eofelis
,
Nimravus
, and
Eusmilus
are too small for this canine. We think that it belongs to
Dinailurictis bonali
.
UM VBOA3-15, distal right humerus, has only a part preserved, the epitrochlear arch is lacking (
Fig. 5A
). The size is intermediate between lion and leopard. The medial lip of the trochlea is less projecting than in modern large cats. It is may be an indication of a different way of running,
Dinailurictis
being less cursorial, a projected lip fixing better the elbow joint in cranio-caudal movements. The cranial fossa for receiving the olecranon process of the ulna is quite deep. The size fits
Dinailurictis bonali
.
UM VD-45, a distal left ulna (
Fig. 5C
), whose size is intermediate between lion and leopard, is characterized by a high and sharp interosseous crest.
UM VBOA3-16, a proximal right femur (
Fig. 5B
), consists of a small part of femur whose size is also intermediate between those of leopard and lion. The inter-trochanteric crest is well developed and the trochanteric fossa is deep. The small trochanter projects well laterally.
