The foramen magnum is a very important feature in bipedal mammals. One of the attributes of a biped's foramen magnum is a forward shift of the anterior border of the cerebellar tentorium; this is caused by the shortening of the cranial base. Studies on the foramen magnum position have shown a connection to the functional influences of both ...
The forehead of the chimpanzee receded to form a heavy browridge and a jutting jaw; the Taung Child's forehead recedes but leaves no browridge. Its foramen magnum, a void in the cranium, where the spinal cord is continuous with the brain, is beneath the cranium so the creature must have stood upright. [33] This is an indication of bipedal ...
The skull was an indicator of orthograde posture because of the location and orientation of the foramen magnum. The foramen magnum is the space in the skull that acts as the bridge to the central nervous system from the spinal cord to the brain. For animals with "pronograde posture, the foramen magnum is dorsally oriented, whereas in humans it ...
Foraging for food in the shorter trees while standing bipedally allows for the chimps to reach higher up so they can get food more easily. [2] In orangutans, bipedalism is more often considered an extension of "orthograde clamber" rather than an independent form of locomotion. Orthograde clamber is when the majority of the body mass is held up ...
Ape skeletons. A display at the Museum of Zoology, University of Cambridge.From left to right: Bornean orangutan, two western gorillas, chimpanzee, human. The evolution of human bipedalism, which began in primates approximately four million years ago, [1] or as early as seven million years ago with Sahelanthropus, [2] [3] or approximately twelve million years ago with Danuvius guggenmosi, has ...
The teeth, brow ridges, and facial structure differ markedly from those found in modern humans. Cranial features show a flatter face, U-shaped tooth rows, small canines, an anterior foramen magnum, and heavy brow ridges. The only known skull suffered a large amount of distortion during the time of fossilisation and discovery, as the cranium is ...

Beetles in the family Carabidae, generally have prognathous heads prognathous
