Cranimagnus Research Paper
Two fossil species of hominin were uncovered at different search sites in East Africa first being the Bigapithecus ginormous and Monocorpus craniomagnus in the other. I Based on the form and characteristics observed from the fossils found, we can describe the socio-ecology of the two different species.
On the first site we discovered the species Bigapithecus ginormous. Based on the mandibles found on site, we identified that the teeth had high cusps and thin molar enamel. High cusps are meant for slicing and shearing along with the thing molar enamel creates very sharp edges on the teeth. We can conclude that this species were leaf eaters because the teeth of leaf eaters contain well-developed molar crests and small incisors. These hominin …show more content…
There was enough postcranial material to estimate the body sizes of both males and females. The male body weight about eighty-three kilograms and the female weighed about forty-seven kilograms suggesting sexual dimorphism, where there are noticeable differences between body size or morphology in males and females. …show more content…
Which means they lived in a social organization that was composed of multiple males and multiple females. Since there are is not one male or one female “controlling” the mating then the mating system must be polygynandry (promiscuity) where both males and females with mate with more than one partner. Frequent competition over which males which mate with which female. (book)
Since there are multiple individuals of each sex then the group must be large. With larger groups, they must travel further in order for the whole group to get food. (video 06,04) The larger the group decreases the rate of predation. (06,05)
A living primate species that might be considered as a reasonable model for the Bigapithecus ginormous would be a chimpanzee or a bonobo.
On the second site where Monocorpus craniomagnus was found there was less material to work with.We discovered that they possess molars that were large, low, and rounded in shape, and containing a thick enamel. This type of teeth suggests that this species is a fruit eater, or frugivore. They have large broad incisors and low rounded molars for piercing the fruit husk and grinding the fruit. Frugivore have a relative simple gut and a long small intestine with allows some fermentation of fiber. (video
