A separate study found American lions were more sexually dimorphic than modern lions in terms of size: American lion males being 1.4 times larger than females, compared to modern male lions being 1.26 times larger. [10] In 2008, the American lion was estimated to weigh up to 420 kg (930 lb).

The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [ 2 ] [ 1 ] Neuron counts constitute an important source of insight on the topic of neuroscience and intelligence : the question of how the evolution of a set of components and parameters (~10 11 neurons, ~10 14 synapses) of a complex system leads to ...
Mountain lions in the greater Los Angeles region are consciously shifting their activity to avoid interacting with human residents, a new study has found. Big cats living in areas with higher ...
Brain size usually increases with body size in animals (i.e. large animals usually have larger brains than smaller animals); [4] the relationship is not, however, linear. Small mammals such as mice may have a brain/body ratio similar to humans, while elephants have a comparatively lower brain/body ratio. [4] [5]
Male lion skins had manes of varying colouration and length. [2] Head-to-tail length of stuffed males in zoological collections varies from 3.0 to 3.5 m (9 ft 10 in to 11 ft 6 in), and of females around 2.5 m (8 ft 2 in). Skull size varied from 30.85 to 37.23 cm (1 ft 0.15 in to 1 ft 2.66 in).
That way the lion vocalisations are directly comparable to those of the humans speaking conversationally,” Dr Clinchy explained. Fear of the human “super predator” pervades the South African ...
In the western United States and Canada, the name mountain lion is commonly used, first seen in writing in 1858.

[14] "Panther" is often used synonymously with cougar, puma or mountain lion. [15]
