Three newHomo erectus mandibles from Java

There are now eleven manidublar pieces from the Lower and Middle Pleistocene of Java, all but one being from the Sangiran site. All of these have been assigned toHomo erectus by most workers, while others have suggested as many as four different hominoid taxa. Sangiran 21 (Mandible E), Sangiran 22 (Mandible F), and Sangiran 37 (Mandible G) are described here fully for the first time. Sangiran 21, 22, and 27 all come from the Upper Pucangan Formation and date approximately 1.2 Myr. The new mandibles are morphologically compatible with theH. erectus, crania from Java.
