| According to caves drawings, male specimens of ice age cave lions lacked a mane. Ethological observations of the recent subspecies showed the significance of the mane of male lions (Panthera leo) in intraspecific social interaction. For the Pleistocene lion, there are two possible implications; the social system was different from the modern subspecies or the cooler climate did not allow the development of manes. Whereas the former can only be discussed, the latter is supported by evidence based on infrared thermography and considerations on thermoregulation. Thermal images of the recent subspecies clearly demonstrate the significance of mane development in terms of functional morphology. Probably, manes in felids can develop in warm climate only. The mane... |

| A divided infraorbital foramen is an important morphological feature in lion taxonomy and has previously been considered to occur only in the Asian lion, Panthera leo persica. Based on an examination of 498 lion skulls from museum collections in Europe and southern Africa, we report for the first time on the prevalence of the divided infraorbital foramen in African lions, as well as its occurrence in the tiger, P. tigris and the extinct Pleistocene European cave lion, P. leo spelaea. The higher frequency of this characteristic in Asian lions may have occurred after the lion colonised Asia, and can be considered an important morphological feature characterising this population. It is not clear whether recent anthropogenic population bottlenecks have... |
