KNM-ER 406 is a nearly complete adult male Paranthropus boisei.It has the facial and cranial features typical of the species such as massive cheek teeth, and the widely flaring zygomatic arches with a forward placed connection to the other facial bones, and large cheek bones supported powerful chewing muscles - the latter two features giving it a "dish-shaped" face.

Paranthropus boisei. Paranthropus boisei, conocido comúnmente como el «Hombre de Nutcracker,» es una especie de homínido que vivió en África Oriental hace aproximadamente entre 2.3 y 1.2 millones de años. Esta especie es particularmente fascinante debido a sus características físicas únicas y su importancia en la historia de la ...
El primer Paranthropus boisei apareció en BK, Lower Bed II, Garganta de Olduvai, en 1955: OH3 (Olduvai Hominid 3), con caninos deciduos y una gran corona molar decidua. Pero su taxonomía permaneció incierta hasta que Mary y Louis Leakey descubrieron OH5 en julio de 1959, datado en 1,8 Ma, conocido como Dear boy (Cascanueces).
Paranthropus is a genus of extinct hominin which contains two widely accepted species: P. robustus and P. boisei. However, the validity of Paranthropus is contested, and it is sometimes considered to be synonymous with Australopithecus. They are also referred to as the robust australopithecines.
P. boisei had the largest supraorbital torus of the robust forms. They were somewhat more encephalized than past species, with a cranial capacity of 514 cc (range = 494–537 cc). Like all australopiths, the species was sexually dimorphic, with males at 4’6″ (137 cm) tall and 108 lb (49 kg) and with more pronounced sagittal-nuchal crests ...
28 de nov. de 2007 · Paranthropus boisei is a hominin taxon with a distinctive cranial and dental morphology. Its hypodigm has been recovered from sites with good stratigraphic and chronological control, and for some morphological regions, such as the mandible and the mandibular dentition, the samples are not only relatively well dated, but they are, by paleontological standards, reasonably-sized.
