There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Asiatic cheetahs

A review of ecology and conservation status of Asiatic cheetah in Iran
In Iran, we collected morphological data from 18 cheetahs from the subspecies range in Iran as well as literature (Hunter et al. 2007; Supporting Online Material SOM Table T1). Adult Males weight range from 25 to 38 kg while females vary between 23 and 35 kg, resulting in a smaller body size of Asiatic cheetahs than the Africans (SOM T1).

Christensen also reports a cheetah specimen to have a upper canine anteroposterior diameter of 2.82 cm, a upper canine lateromedial diameter of 0.89 cm, a lower canine anteroposterior diameter of 1.05 cm and a lower canine lateromedial diameter of 0.76 cm.Therrien reports a mandibular length of 11.84 cm for cheetahs.One asiatic cheetah from iraq had a condylobasal length of 15.63 cm, zygomatic breadth of 11.41 cm, interorbital breadth of 4 cm, braincase width of 6 cm, canine to molar distance if 5.32 cm and a mandible length of 11.96 cm.

In Libya 3 female cheetahs had a zygomatic width of 10.06 cm, upper tooth row length of 4.7 cm and a mandible length of 10.28 cm.(6,7,8,10,17)



Skull structure
Cheetah skulls are highly domed in lateral aspect.The zygomatic arch is broad anteriorly and much narrower posteriorly.The Maxillary process is short and very little salient.The maxillary process does not in anyway overhand the infraorbital foramen.In postorbital processes tare very short and blunt.The vertical branch of the premaxilla protrudes only a short distance between the maxilla and the nasal.The nares are very large.The braincase is very rounded  and there is usually little evidence of a Sagittal crest except at the extreme posterior.Ventrally the palate is short and broadly triangular. The post dental palate has sharp sloping sides.The hamulars are broad hooks.The bullae is inflated but it is relatively small for the overall size of the skull.The mandible is not particularly strongly built.The dentition is distinctive.The cheek teeth are nominally 3.1 / 2.1. The space between the canine and the first premolar is usually narrow.The jaws have little sign of any postcanine gap.The canines exhibit little or no sign of furrowing.The miracinonyx species also have similar skull structure. Cheetah canines are small, hooked backwards and have grooves that are absent or faint. Nasals are Straight to Concave.(11,12,13)


Size of skull in comparison to the members of the puma lineage
Cheetahs have larger skulls than jaguarundis.There are no significant difference between pumas and cheetahs in the main axis of the skull (length, width,height) and 12 out of 20 skull measurements. Pumas score better in mastoid breadth,temporal fossa length, tooth row length and jaw width. Cheetahs score better in masseteric scar length, post orbital constriction breadth, condyle to length of jaw and orbit to premaxillae length.(14)

Good job collecting this info. Are you sure the skulls from the Namibian farmlands were dried skulls? They seem to be very different from other Namibian cheetah skulls in size.
