During the Pre-Historic Era, certain creatures and species were limited in their access to food supplies, and so they were forced to feed on their own kind, giving them the ability to sustain their lives a bit longer.
Majungatholus
In 1998, paleontologist/anatomist Scott Sampson from the New York College found a Majungatholus skull, making it the most well preserved dinosaur skull ever found. Sampson said, "It's the kind of face that only a mother could love. It had textured, convoluted bone all over the surface of the skull which probably had skin tightly adhering to it. It had this horn-like structure on the top of the head between the eyes and another projection at the back of the skull as well."
Teeth marks along with serrated smaller notches were found embedded on the Majungatholus measuring the same width as the teeth on the dinosaur itself, implying that it may have been involved in a struggle with the same species.
Neanderthals
Around 43,000 years ago, the Neanderthals were turning to cannibalism—even brain-eating. Discoveries of fossil remains suggest that these prehistoric humans looked entirely different from their northern counterparts. The Osteology of this species clearly suggests signs of dismemberment and skinning.
Cannibalistic actions included cutting of the flesh, using small stone tools and smashing open the skull using larger tools to access the brain and marrow.
“Reports of the Neandertals (often spelled "Neanderthals") ate their own kind, says paleoanthropologist Antonio Rosas of the National Museum of Natural Sciences in Madrid. Rosas is the lead researcher for the study, which is published today in the journal Proceedings of the National Academy of Sciences.”
Anasazi
MesaVerde
Around 900 AD in the Chaco Canyon, the Anasazi of the southwestern U.S. routinely "processed their colleagues . . . skinned them, roasted them . . . severed their joints . . . and put the pieces into pots. This gives an entire new meaning to vicious and bizarre." Unfortunately, history has continued to be a distressing chronicle of man's inhumanity to man. Today, Chaco Canyon is a Mecca for New Agers. They like to believe that Anasazi existed in full harmony with nature. However, the archaeological evidence is exceedingly “inconvenient for those who argue that man in his natural state was good and that civilization as we know it is evil.”
Cave Bears
Scientists have always believed that these creatures were gentle, feeding solely on vegetables and fruits. However, bones were discovered in the Carpathians - the mountains where Dracula supposedly dwelt – suggesting that cave bears could have also been cannibals. Ongoing studies of their bones and other accessory organs suggest that only a certain cave bear, dwelling in the Carpathians were carnivorous. They had high levels of Nitrogen 15 in their bones, which was highly bizarre considering that cave bears normally had low levels of Nitrogen-15.
Ultimately, Cave bears died out around 20,000 years ago when the ice had dominated the earth.
