A primitive Late Pliocene cheetah, and evolution of the cheetah lineage.
The cheetah lineage is a group of large, slender, and long-limbed cats with a distinctive skull and dental morphology, of which only the extant cheetah (Acinonyx jubatus) is present today. The lineage is characterized by having abbreviated, tall, and domed crania, and a trenchant dentition with a much reduced, posteriorly placed protocone on the upper carnassial. In this article, we report on a...
متن کاملThe cheetah: native american.
Two North American fossil species of large felids, hitherto regarded as Late Cenozoic pumas (mountain lion), are in fact closely related to the living cheetah, Acinonyx, of Africa and Eurasia. A new subgenus (Miracinonyx) is proposed for the American species. Cheetahs and pumas may have had a common ancestor in the Miocene of North America.
متن کاملThe composition of cheetah (Acinonyx jubatus) milk.
Milk was obtained from two captive bred cheetahs. The nutrient content was 99.6 g protein; 64.8 g fat; and 40.21 g lactose per kg milk. Small amounts of oligosaccharides, glucose, galactose and fucose were noted. The protein fraction respectively consisted of 34.2 g caseins per kg milk and of 65.3 g whey proteins per kg milk. Very little variation in milk composition among the individual cheeta...
متن کاملThe cheetah (Acinonyx jubatus) dewclaw: specialization overlooked
Both the behavioural and the morphological analyses confirm the special role of the dewclaw in the cheetah: a strong hook to stop running animals by using the energy of the victim itself. However, this would hardly be an explanation for the rather large dewclaw in the puma. The present finding of the puma as an intermediate between the cheetah and other large felids for dewclaw size, supports t...
متن کاملDevelopment and Test of a Model for the Cheetah Robot
This project aims at implementing a close-to-reality model of the recently developed Cheetah robot [1] in Webots [2], a commercial mobile robot simulation software developed by Cyberbotics Ltd. Furthermore, a pre-developed CPG [3] will be applied to the robot to determine feasible gaits and their optimal parameters for the Cheetah robot. Special interest lies in the characterization of the usef...
