OBJECTIVES
The purpose of this work is to present a new primate locality with evidence that increases the knowledge on the radiation of the extinct platyrrhine primates.
MATERIALS AND METHODS
We studied the new specimen and compared it to specimens identified as Mazzonicebus almendrae.
RESULTS
The new first and second molars were comparable to Mazzonicebus almendrae in all morphological details, allowing us to allocate the new specimen to M. almendrae and add comments on morphological variation in this species regarding the orientation of the labial cristae and development of the anterolingual cingulum. This new maxilla also present the first known M3 for the species.
DISCUSSION
The new specimen increases our knowledge of the extinct platyrrhines from Patagonia. Their age and geographical distribution ranges from early to middle Miocene in an area between 40° to 47° of southern latitude.
目的
本研究旨在介绍一个新的灵长类动物产地，并提供证据以增进我们对已灭绝阔鼻猴灵长类动物辐射演化的了解。
材料与方法
我们研究了新标本，并将其与鉴定为阿尔门德拉马佐尼猴（Mazzonicebus almendrae）的标本进行比较。
结果
新的第一和第二磨牙在所有形态细节上都与阿尔门德拉马佐尼猴相似，这使我们能够将新标本归入阿尔门德拉马佐尼猴，并对该物种唇嵴方向和前舌侧边缘嵴发育方面的形态变异进行评论。这块新的上颌骨还展示了该物种已知的第一颗M3。
讨论
新标本增加了我们对巴塔哥尼亚已灭绝阔鼻猴的了解。它们的年代和地理分布范围是中新世早期到中期，位于南纬40°至47°之间的区域。
