what is the average weight of human head
Human head For humans, the head and particularly the face are the main distinguishing feature between different people, due to their easily discernible features such as hair and eye color, nose, eye and mouth shapes and wrinkles. The human head typically weighs between 5 and 11 pounds (2.3 and 5.0Â kg). Human faces are easily differentiable to us due to our brains' predispositions toward discriminating human facial forms. When observing a relatively unfamiliar species, all faces seem nearly identical, and human infants are biologically programmed to recognize subtle differences in anthropic facial features.[citation needed]
Short-faced bear In a recent study, the mass of six A. simus specimens was estimated, one-third of them weighed about 900 kg (1 short ton), the largest being UVP 015 at 957 kg (2,110 lb), suggesting specimens that big were probably more common than previously thought.[2] It stood 8–10 feet (2.4–3.0 m) tall on hind legs[8] while a large specimen would have been 11–12 feet (3.4–3.7 m) tall with a 14-foot (4.3 m) vertical arm reach. When walking on all fours, it stood 5–6 feet (1.5–1.8 m) high at the shoulder: It was tall enough to look a man in the eye.[9][10][11] At Riverbluff Cave, Missouri, a series of claw marks up to 15 feet (4.57 m) high have been found along the cave wall indicating short-faced bears up to 12 feet (3.66 m) tall.[12][13]
