Homo rudolfensis is an extinct species of archaic human from the Early Pleistocene of East Africa about 2 million years ago (mya). Because H. rudolfensis coexisted with several other hominins, it is debated what specimens can be confidently assigned to this species beyond the lectotype skull KNM-ER 1470
Jan 3, 2024 · Was Homo rudolfensis on the evolutionary lineage that evolved into later species of Homo and even perhaps our species, Homo sapiens? Are Homo rudolfensis and Homo habilis indeed different species, or are they part of a single, variable species? Or was one the ancestor of the other?
Apr 25, 2023 · Homo rudolfensis is an early human species that lived in East Africa between c. 2.5 and 1.8 million years ago. It is known from a handful of skull, jaw and teeth fragments that remind alternatingly...
The scientific name Homo rudolfensis was originally proposed for the specimen skull KNM-ER 1470, discovered in 1972. It was once thought by many to be a member of the species Homo habilis but the differences compared to other Homo habilis skulls were considered too great.
Today, most scientists now accept KNM-ER 1470 as belonging to Homo rudolfensis-- as species that co-existed in the Turkana Basin, northern Kenya, with three other species sometime between 2.0 and 1.5 million years ago: Homo habilis, Homo erectus, and Paranthropus boisei.
H. rudolfensis is named for the fossil KNM-ER 1470, found on the east side of Lake Rudolf (now Lake Turkana) in Kenya. KNM-ER 1470 most clearly exemplifies H. rudolfensis and is characterized by a large cranial capacity (around 750 cc), large cheek teeth, and a long face that is broad across the orbits (eye sockets) and flattened below the nose.
The second species of Early Homo to be discovered is now known as Homo rudolfensis, since it was discovered at the site of Koobi Fora on the east side of Lake Turkana, which was formerly known as Lake Rudolf.

Aug 8, 2012 · A study published this week in Nature 1 focuses on Homo rudolfensis, a hominin with a relatively flat face, which was first identified from a single large skull in 1972. Several other big-skulled...
Jan 1, 2021 · Homo rudolfensis is a species of early Homo that is known from ~1.8 million years ago in East Africa. Despite more than 40 years of research and analyses, it is still unclear where this hominin sits on the human evolutionary tree.
