Paranthropus boisei

Paranthropus boisei is an extinct australopithecine. It is the largest of the Paranthropus species. Its scientific name is abbreviated P. boisei. 

P. boisei lived 2.3 million years ago to 1.2 million years ago, during the Pliocene and Pleistocene epochs in Eastern Africa. It may have evolved from Paranthropus aethiopicus. It is not a direct ancestor of modern humans. 

The species was originally called Zinjanthropus boisei, and then renamed Australopithecus boisei until recently. 

 Features 
P. boisei had a specialized skull with adaptations for chewing power. In fact, archaeologists nicknamed it "the Nutcracker Man" because its jaws and teeth were so large and powerful. These enabled P. boisei to chew tough foods like roots, stems, and nuts. However, analysis of fossil teeth shows that P. boisei probably had a varied diet and did not depend completely on tough or hard foods.

Based on fossil skull sizes, scientists think P. boisei might have had a slight rise in brain size over time (about 100 ml in 1 million years). 

P. boisei "had gorilla-like strength alongside the dexterity to make tools," according to one source. Fossils confirm that P. boisei's hands were capable of tool making.
