Decorated human jaw found in Mexico

A 1,300-year-old carved and painted human jaw has been found at a Zapotec site in southern Mexico. When archaeologists excavated the complex, they found that it had been inhabited for at least 400 years. "We think that these residences were occupied by a series of families that were related to each

Ancient human jaw found in Siberia

A human jawbone thought to date back 14,000 years has been found at Afontova Mountain in Siberia ahead of bridge construction. Embedded in a hillside where it has lain for around 14,000 years, the adult jaw from Afontova mountain on the outskirts of Krasnoyarsk was found alongside the bones of animals

Human ancestors used toothpicks

New evidence suggests that humans were using toothpicks 1.8 million years ago. "Progressive tooth wear triggers bone remodelling processes that substantially modify the shape of the jaw during an individual's lifetime. These effects are typically underestimated when attributing fossil hominid jaws to different species," she told BBC News. "The individual who was

Shift from hunting to farming changed our faces

New research indicates that the shift from being hunter-gatherers to farmers may have altered the shape of our jaws. A number of researchers have hypothesized that the advent of agriculture, which led to diets consisting of softer foods that required less chewing, led to modifications in the lower jaw, either through

3-D model of ancient sea creature’s scary jaws

That image above shows the jaws of a conodont, a 250-million-year-old eel-like creature. Researchers are studying it in hopes of finding out more on how jaws might have evolved, which apparently is still sort of an enigma. The mouths that emerged might look monstrous by our standards. Apparently, most conodonts had

“Nutcracker Man” ate grass

New studies have shown that the ancient hominid Paranthropus boisei, better known as Nutcracker Man, preferred to eat grass. Professor Matt Sponheimer said it was long assumed Paranthropus boisei favoured nuts, seeds and hard fruit because of its powerful jaw muscles and the biggest and flattest molars of any known

Why do mummies look like they are screaming?

Pain and agony are written onto the faces of mummies found world-wide, their mouths agape as if frozen mid-scream. Now one researcher has unlocked the reason why. "This temporo-mandibular joint is fairly loose.... Unlike the tight ball-and-socket linking the leg and the hip, the jaw and cranium are held together only
