P. troglodytes Skull Replica measures 8.25 inches. P. troglodytes Skull Replica is museum quality polyurethane cast. Known as the Chimpanzee. 2-part skull (separate cranium and jaw). Cast of an original California Academy of Sciences. Made in USA. Our precise skull can be used as a teaching tool, museum skull exhibit, home decor skull, or office decor skull.
A P. troglodytes has a head and body length ranging between 635 and 925 mm. When standing erect, they are 1 to 1.7 m tall. The arms are long, such that the spread of the arms is 1.5 times the height of an individual.
Their legs are shorter than are the arms, which allows Chimpanzee or Pan troglodytes to walk on all fours with the anterior portion of the body higher than the posterior.
P. troglodytes have very long hands and fingers, with short thumbs. This hand morphology allows chimpanzees to use their hands as “hooks” while climbing, without interference from the thumb.
In trees, P. troglodytes may move by swinging from their arms, in a form of brachiation. Although useful in locomotion, the shortness of the thumb relative to the fingers prevents precision grip between the index finger and thumb. Instead, fine manipulations require the Pan troglodytes to using the middle finger in opposition to the thumb.
P. troglodytes have prominent ears, and a prominent superorbital crest. This gives the brows a somewhat rigid and bony appearance. Cranial capacity of these animals ranges from 320 to 480 cc.
The P. troglodytes lips protrude and are very flexible, allowing an individual to accomplish many tasks through labial manipulation. Dentition is typical of primates. Their dental arch is square in shape, and there is a prominent diastema.
Their canines are large, as are molars. Molars decrease in size toward the back of the mouth.
The face of an adult is typically black, or mottled with brown. Hair is black to brown, and there is no underfur present. There may be some white hairs around the face.
They live in groups that range in size from 15 to 150 members, although individuals travel and forage in much smaller groups during the day.
The species lives in a strict male-dominated hierarchy, where disputes are generally settled without the need for violence.
Nearly all chimpanzee populations have been recorded using tools, modifying sticks, rocks, grass and leaves and using them for hunting and acquiring honey, termites, ants, nuts and water.
The P. troglodytes species has also been found creating sharpened sticks to spear small mammals.
Its gestation period is eight months. The infant is weaned at about three years old but usually maintains a close relationship with its mother for several years more.
The chimpanzee has an advanced cognitive map of its home range and can repeatedly find food.
The P. troglodytes builds a sleeping nest in a tree in a different location each night, never using the same nest more than once. Chimpanzees sleep alone in separate nests except for infants or juvenile chimpanzees, which sleep with their mothers.
The chimpanzee is an omnivorous frugivore. It prefers fruit above all other food items but also eats leaves, leaf buds, seeds, blossoms, stems, pith, bark, and resin.
While the chimpanzee is mostly herbivorous, it does eat honey, soil, insects, birds and their eggs, and small to medium-sized mammals, including other primates. Insect species consumed include the weaver ant Oecophylla longinoda, Macrotermes termites, and honey bees.
The Red Colobus ranks at the top of preferred mammal prey. Other mammalian prey include Red-tailed Monkeys, infant and juvenile Yellow baboons, Bush babies, Blue duikers, Bushbucks, and common Warthogs.
