SK 48 is a fossilized skull of the species ''Paranthropus robustus''. It was found at Swartkrans, South Africa in 1948 by Robert Broom. It is estimated to be 1.8 million years old. It is characterized by a robust appearance, bulging and continuous brow, broad flat face and a deep jaw with large chewing teeth/muscle attachments. The mandible SK 23 was discovered at the same time and in the same location. Even though studies indicate that it came from a separate individual, the two fossils are considered so closely related that they can be studied together. The mandible is also very robust and contains a complete dentition. ==See also== * List of fossil sites ''(with link directory)'' * List of hominina (hominid) fossils ''(with images)'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SK 48」の詳細全文を読む スポンサード リンク
