晚中新世巨猿头骨是罕见的，大多是碎片，并且是关于巨猿和人类起源的许多争论的焦点（Brown & Ward，1988; Bonis等人，1990; Moyà-Solà & Köhler，1993，1995; Begun，1994; Kordos & Begun，1997; Schwartz，1997）。由于保存不佳，颅骨解剖学的重要特征（面部成角，下颌骨，相对和绝对脑大小）的信息必须从不完整或重建标本估计。这导致了对原始人类头骨形态进化历史的分歧，并导致了关于现生原始人类（猩猩和人类）的起源和组成的不确定性。在这篇初步的通讯中，我们报告了在匈牙利Rudabánya发现的一个新的森林古猿头盖骨。这是迄今为止发现的最完整的头骨。该标本编号为RUD 197-200，包括一个几乎完整的齿系，以及在森林古猿中首次发现的一个脑颅，脑颅具有完整的眉间至隆突索，并与上颌骨直接骨性接触。缺乏标准的解剖学标志，妨碍了对面部轴的明确测量，而且脑颅也不完整
Late Miocene great ape crania are rare, mostly fragmentary, and the focus of much debate on great ape and human origins (Brown & Ward, 1988; Bonis et al., 1990; Moyà-Solà & Köhler, 1993, 1995; Begun, 1994; Kordos & Begun, 1997; Schwartz, 1997). Due to poor preservation, information on important features of cranial anatomy (facial angulation, prognathism, relative and absolute brain size) must be estimated from incomplete or reconstructed specimens. This has led to disagreement on the evolutionary history of hominid cranial morphology and contributes to uncertainty with regard to the origin and composition of the clades of living hominids (pongines and hominines). In this preliminary communication we report on the discovery of a new cranium of Dryopithecus brancoi from Rudabánya, Hungary. It is the most complete cranium of this taxon ever recovered. The specimen, RUD 197–200, includes a nearly complete dentition and, for the first time in Dryopithecus, a neurocranium with a complete glabella to inion chord with direct bony contact to the maxilla. Standard anatomical landmarks are lacking, preventing unambiguous measurement of facial hafting, and the neurocranium is not complete
