This award will support collaborative research between Dr. Larry G. Marshall Institute of Human Origins, Berkeley, California and Dr. Christian de Muizon of the Institute of Paleontology, National Museum of Natural History, Paris, France. Drs. Marshall and de Muizon have worked together successfully in the past in the collection of mammals and other vertebrates from the Late Cretaceous age El Molino Formation in Bolivia. The investigators now propose to prepare two monographs on some the most important species in the oldest mammalian faunas of South America. Monograph 1 will be on specimens of Alcidedorbignya inopinata--the _______________ _________ earliest, smallest, and most generalized member of the order Pantodonta known. Monograph 2 will be on specimens (including complete skulls and nearly complete associated skeletons) of the didelphid marsupial Pucadelphys andinus. A. inopinata is the most ___________ _______ _ _________ abundant placental, and P. andinus is the most abundant marsupial _ _______ in the Tiupampa fauna. Preparation of both monographs will involve: 1) assessment of dental variation within each species; 2) assessment of possible sexual dimorphism within each species; 3) detailed descriptions of all dental, skull, and postcranial elements; 4) comparative descriptions and assessment of phyogenetic affinity with other taxa; 5) assess functional aspects of the skeletons of Pucadelphys; 6) make photographs for study and ___________ publication; and 7) discuss the evolutionary and biogeographic importance of each species. The results of this work should be of great interest to scholars of mammalian evolution.

该奖项将支持拉里·G博士之间的合作研究。马歇尔人类起源研究所，伯克利，加州和博士基督教德Muizon的古生物学研究所，国家自然历史博物馆，巴黎，法国。马歇尔博士和de Muizon博士过去曾成功地合作，从玻利维亚的晚白垩世埃尔莫利诺组收集哺乳动物和其他脊椎动物。研究人员现在建议编写两本关于南美洲最古老的哺乳动物群中一些最重要物种的专著。专著1将是关于Alcidedorbignya inopinata的标本--已知的全齿目中最早、最小和最普遍的成员。专著2将是关于有袋类Pucadelphys andinus的标本（包括完整的头骨和几乎完整的相关骨骼）。A.在Tiupampa动物群中，inopinata是最丰富的胎盘动物，P. andinus是最丰富的有袋动物。这两本专著的编写将包括：1）评估每个物种内的牙齿变异; 2）评估每个物种内可能的两性异形; 3）详细描述所有牙齿、头骨和颅后元素; 4）比较描述和评估与其他分类群的亲缘关系; 5）评估Pucadelphys骨骼的功能方面; 6）拍摄照片用于研究和出版; 7）讨论每个物种的进化和地理学重要性。这项工作的结果应该会引起哺乳动物进化学者的极大兴趣。
