The answer is Paranthropus boisei or P. Boisei. This specie was the earliest hominin and is also described as the largest of the Paranthropus family. This species of Paranthropus lived in Eastern Africa from 2.4 until 1.4 million years ago. Archaeologists found hominid bones along with early stone age technology, which was uncovered to be bones of Paranthropus Boisei.
