9316895 Miller PI, collaborator Oscar Carranza (UNAM, Mexico), and an assembled team of experts will collect and study Mio-Pliocene-age vertebrate fossils from key localities in central Mexico. They will obtain greater chronostratigraphic precision for this time period in the terrestrial record, including magnetostratigraphy, and radiometric dates from ash beds within the fossil-bearing sequences. This study will help date earliest occurrences of important mammalian taxa, including South American immigrants, and provide valuable data for comparisons with similar fossil-bearing sequences elsewhere in North America.

小行星9316895米勒 PI，合作者Oscar Carranza（墨西哥国立自治大学）和一个专家小组将收集和研究墨西哥中部主要地区的中新世脊椎动物化石。 他们将在陆地记录中获得这一时期更高的年代地层学精度，包括磁性地层学和含化石序列内灰层的放射性测年。 这项研究将有助于确定最早出现的重要哺乳动物类群，包括南美移民，并为与北美其他地方类似的化石序列进行比较提供有价值的数据。
